Custom Single-Acting Ram / Plunger Hydraulic Cylinder APEX-CSPC Series
High-Force Lifting and Pressing Actuators Built to Your Specifications
Product Overview
The APEX-CSPC series is a family of custom single-acting hydraulic cylinders designed for applications requiring high linear output force from a simple hydraulic circuit. Built with heavy-wall seamless steel cylinders and hard-chrome-plated alloy steel plungers, these units provide reliable lifting, pressing, and positioning in demanding industrial environments.
Available with bore/plunger diameters from 50 to 400 mm and strokes up to 2500 mm, each cylinder is engineered to match your exact mounting interface, port configuration, and performance requirements. Return methods include gravity, external load, spring, or mechanical linkage, ensuring compatibility with your existing system.
Every unit undergoes pressure, leakage, and full-stroke functional testing before shipment, supported by dimensional inspection and quality control.
Key Benefits
- High linear force with a simple hydraulic circuit – only one pressure line required
- Gravity-return version ideal for vertical lifting applications
- Spring-return offers automatic retraction in compact equipment
- Large-diameter ram options deliver high lifting or pressing capacity
- Optional spherical saddles improve load contact with minor angular misalignment
- Custom mounting, ports, and load saddles align with your machine design
- Replaceable seals, guides, and wipers reduce maintenance downtime
- Tested for pressure, leakage, and full stroke before delivery
