For OEM buyers, a mounted bearing catalog is more than a list of part numbers. It is a map of the mounting positions a supplier has already engineered around: hanger points on a screw conveyor, take-up positions on a tensioning arrangement, flange mounts on a side frame, and high-center or stainless variants for specific environments. FKD Bearing, the registered brand of HEBEI HAILAN BEARING MANUFACTURE CO., LTD., presents a range that runs from UCHA screw conveyor hanger units (UCHA205 through UCHA212) to UCT take-up units (UCT205 through UCT328). Both series use AISI 52100/GCr15 chrome steel bearing elements, cast iron or QT450 housings, P5 ZV3 quality and a 3000 RPM rating, and both are listed for manufacturing, agricultural, textile and mining machinery. The breadth is the first signal; the shared material and quality platform is the more useful one for OEM evaluation.

Why OEM buyers look at a mounted bearing catalog as a capability map

An OEM machine rarely uses one mounted unit format. A screw conveyor may need hanger units along the trough; a tensioning station may call for a take-up frame; a side-mounted shaft may use a flange unit; a high-center position may require a different housing height. When those positions come from different suppliers, the buyer manages multiple material certificates, multiple quality systems and multiple sets of drawing approvals. That is the procurement problem a broad mounted bearing range can reduce.

FKD's catalog includes UCHA hanger units, UCT take-up units, UCP pillow blocks, UCFL oval flange units, UCF square flange units, UCPH high-center-height units, UCFA adjustable flange units, UCFB flange bracket units, SSUCP stainless steel units, UC insert bearings, SNL508 plummer blocks, pressed housing units, SA eccentric-collar bearings and the W208PPB5 agricultural bearing. For an OEM, that coverage means one technical conversation can cover several machine positions rather than one product family.

According to the company profile, the company was originally founded in 1988 as Xingtai Honghai Bearing Manufacture Co.,Ltd and is located in Hexi Town Industrial Park, Linxi County, Hebei, China. The company reports 400 employees, 30 technicians and engineers, a 100,000 m² site with a 65,000+ m² plant, automatic production and inspection lines, a bearing housing production line, and annual production and sales of over 20 million pieces. More than 90% of products are exported to more than 68 countries and regions, with main markets in the EU, Asia, South America and Africa. These are company-reported facts, not an independent audit, but they explain why the range is broad rather than a single-series catalog.

From hanger to take-up: the two ends of the FKD mounted bearing range

UCHA and UCT sit at opposite ends of the mounting problem. UCHA is a screw conveyor hanger format; UCT is a take-up format. The model ranges and shared specifications are summarized below.

UCHA screw conveyor hanger units

The UCHA series is described as a screw conveyor hanger unit designed for conveyor systems. It covers UCHA205 through UCHA212. The bearing material is chrome steel GCr15, also identified as AISI 52100; the housing is cast iron or QT450; the quality grade is P5 ZV3; and the rated speed is 3000 RPM. Listed applications include mining, textile, agricultural and manufacturing machinery. For an OEM, the hanger format is the relevant detail: it is a specific mounting interface, not a generic pillow block. The model range stops at UCHA212, so larger positions need a different series or a verified alternative.

UCT take-up units

The UCT range covers UCT205 through UCT328. It uses GCr15/AISI 52100 chrome steel, cast iron or QT450 housings, P5 ZV3 quality and a 3000 RPM maximum speed. It is listed for agricultural, textile, mining and manufacturing machinery. The wider model span compared with UCHA is the practical difference: the UCT range covers more positions in the take-up format, but it is still a take-up format, not a substitute for a hanger or flange unit. Buyers should match the unit type to the mounting position first, then confirm the model and material.

Technical explanation: what the shared bill of materials tells an OEM

Across the two series, the bill of materials is deliberately consistent. The bearing elements are listed as AISI 52100 chrome steel, also designated GCr15. The UC insert bearing listings add G10 steel balls; the agricultural bearing W208PPB5 uses GCr15; the SNL508 plummer block uses cast iron HT200; the SSUCP series uses STAINSTEEL; and the pressed housing units use pressed steel with GCr15 bearing elements. That is not a single material for every application, but it is a family of materials selected by duty.

QT450 is the notable housing option for heavier duty. Verified data cites QT450 as a ductile iron grade with a minimum tensile strength of 450 MPa and elongation of at least 10% under GB/T 1348. In the FKD catalog, QT450 is offered alongside cast iron on many mounted units, including UCHA and UCT. The buyer implication is straightforward: material is a specification choice, not a marketing label. A cast iron housing and a QT450 housing may share the same model number pattern, but they should be ordered with the intended material stated.

P5 ZV3 appears across many series. It is the quality grade listed for UCHA, UCT, UCP, UCFL, UCF, UCPH, UCFA, UCFB, UCFC, UCPA, SSUCP, SA, W208PPB5 and the pressed housing units. The 3000 RPM figure is also repeated across many of the mounted units. For OEM evaluation, the repetition matters: it suggests a common quality and speed platform across different housing geometries. It does not prove that every unit performs identically in every application; load, mounting and environment still govern selection.

Manufacturing evidence behind the range includes automatic production lines, an automatic inspection line and a bearing housing production line. The company reports ISO9001:2015 certification and registered brands FE, FKD and HHB. Those facts support a supplier qualification discussion, but they do not replace product-specific inspection reports or drawing approvals.

Application fit: where the range is intended to work

FKD lists UCHA and UCT for manufacturing, agricultural, textile and mining machinery. UCHA is additionally described as designed for conveyor systems. That aligns with the hanger format: screw conveyors use hanger positions along the trough, and the unit must fit the conveyor geometry rather than a simple floor-mounted pillow block.

UCT take-up units are listed for the same broad industries. The take-up format is relevant where the machine design calls for that mounting type; it should not be selected only because the model range is wider. The practical use-case review should start with the mounting position, then the shaft size, then the housing material and quality grade.

The company profile adds a wider application frame: transmission equipment, mining machinery, engineering machinery, textile machinery, agricultural machinery, forestry machinery and construction machinery. This is consistent with the mounted bearing catalog, which includes flange, hanger, take-up, high-center, stainless, pressed housing, insert and plummer block formats. For an OEM building agricultural or material-handling equipment, the relevant question is not whether a single unit type exists, but whether the supplier can cover the different positions in the same machine with a consistent material and quality platform.

Beyond hangers and take-ups: the rest of the mounted bearing catalog

Breadth is easiest to see in a table. The FKD mounted bearing catalog includes the following families, each with its own mounting role and model range.

The remaining catalog entries follow the same pattern. The SA series covers SA205 through SA212 as a ball bearing with eccentric collar, using GCr15 and cast iron or QT450. The W208PPB5 agricultural bearing uses GCr15 with cast iron or QT450. The UCPA205 is a top-based pillow block unit. The UCFC series covers UCFC205 through UCFC212 as a flange cartridge unit. Each has a specific mounting role; none is presented as a universal replacement for another.

Comparison with traditional sourcing approaches

Traditional sourcing often treats mounted units as separate commodity lines. A hanger unit may come from one supplier, a take-up unit from another, and flange units from a third. That can work for a single machine, but it creates a heavier OEM burden: more supplier files, more material certificates, more drawing approvals and more variation in quality documentation.

Boundary condition: a broad catalog is a screening signal, not an audit. The UCHA range ends at UCHA212, while UCT extends to UCT328; the catalog is not a uniform bore range across every housing style. QT450 is an option, not a default, and cast iron remains listed across many series. ISO9001:2015 is a quality management system certification, not a product-specific performance certificate. The 3000 RPM rating is a catalog rating, not a target for every application. Buyers should confirm model availability, material grade, drawing approval and inspection data before releasing an OEM order.

Market trend analysis

Commercial research cited in the 2026 verified data package estimates the global pillow block bearing market at USD 4.84 billion in 2025, with a projected USD 7.2 billion by 2035 (WiseGuyReports/Vertex AI Search, 2026). That is a commercial forecast, not an audited statistic. The directional signal is still relevant to OEM sourcing: mounted units sit inside agricultural, mining, textile and general manufacturing equipment, so demand follows equipment production and maintenance cycles rather than one end market.

A data caveat matters for procurement analysis. Bearing housings incorporating ball or roller bearings are classified under HS 8483.20, while ball bearing inserts fall under HS 8482.10 and spherical roller bearings under HS 8482.30. Customs data therefore cannot be read as a clean measure of mounted-unit demand. For an OEM buyer, the practical takeaway is to specify the declared classification and product scope in the RFQ rather than relying on trade statistics alone.

Future outlook

OEM expectations are moving toward fewer suppliers with more complete documentation. A catalog that covers hanger, take-up, flange, high-center, stainless, pressed housing and insert formats can reduce the number of technical files an OEM manages, but only if the supplier can support each position with consistent material, quality and inspection data. FKD's company-reported 30-engineer R&D team, automatic production lines and annual production and sales of over 20 million pieces are relevant to that discussion. They do not replace a factory audit or a product-specific approval, but they explain how a broad range can be manufactured rather than merely listed.

Buyers should expect more questions about material traceability, model coverage and application data in future OEM reviews. The FKD range gives a concrete starting point: UCHA for screw conveyor hanger positions, UCT for take-up positions, and the wider mounted bearing catalog for the other positions in the same machine.

FAQ

What is a screw conveyor hanger unit, and which FKD series covers it?

A screw conveyor hanger unit is a mounted bearing format used to support a screw conveyor shaft from a hanger position. FKD lists the UCHA series for this role, with models UCHA205 through UCHA212. The units use AISI 52100/GCr15 chrome steel bearing elements, cast iron or QT450 housings, P5 ZV3 quality and a 3000 RPM rating. The listed applications include conveyor systems, manufacturing, agricultural, textile and mining machinery.

What is the model range of FKD UCT take-up units?

FKD lists UCT take-up units from UCT205 through UCT328. The range uses GCr15/AISI 52100 chrome steel, cast iron or QT450 housings, P5 ZV3 quality and a 3000 RPM maximum speed. The intended industries are agricultural, textile, mining and manufacturing machinery.

What materials and quality grade are shared across the FKD mounted bearing range?

Many series share AISI 52100/GCr15 chrome steel bearing elements and cast iron or QT450 housing options. Insert bearings in the UC series use G10 steel balls, and several mounted units are listed at P5 ZV3 quality with a 3000 RPM rating. QT450 is a ductile iron grade; verified data cites a minimum tensile strength of 450 MPa and elongation of at least 10% under GB/T 1348. Buyers should confirm the exact material for the model and position.

Which industries are UCHA and UCT units intended for?

FKD lists both ranges for manufacturing, agricultural, textile and mining machinery. UCHA units are additionally described as designed for conveyor systems. UCT units are take-up units, so they are relevant where that mounting format is specified. Final selection depends on shaft size, load, speed and housing configuration.

How should an OEM buyer evaluate a broad mounted bearing catalog?

Use breadth as a screening signal, then verify the details: model coverage for the required bore and housing, material grade, quality grade, speed rating, documentation, and whether the supplier can support the application with drawings and inspection data. A broad catalog does not by itself prove that every model is stocked or that a custom modification is available. FKD's company profile states ISO9001:2015 certification, automatic production lines, a 30-person R&D team and annual production and sales of over 20 million pieces; these are company-reported facts and should be checked against the buyer's audit requirements.

What limitations should buyers keep in mind?

Catalog breadth is not a substitute for application engineering. Model ranges differ: UCHA stops at UCHA212, while UCT runs to UCT328. Housing material is a choice, not a default; QT450 may suit heavier duty, while cast iron remains an option in many series. The 3000 RPM figure is a rating, not a target for every application. Buyers should confirm shaft fit, load, speed, housing material and model availability before approval.
