Enerpac CST40131 Compact Hydraulic Cylinder Steel

Product Description

The ENERPAC CST40131 is a single-acting compact hydraulic cylinder designed for use in space-constrained applications where reliable linear force output is required. Constructed with a steel body, this cylinder delivers the structural durability expected in industrial and mechanical service environments. The single-acting design uses hydraulic pressure to extend the piston, with load or spring return on the retract stroke. At 2.2 pounds, the CST40131 is lightweight enough for portable setups while still providing the rated output force typical of ENERPAC hydraulic tooling. It is installed by hydraulic technicians, millwrights, and maintenance mechanics across a range of industrial service tasks.

The CST40131 is suited for both horizontal and vertical mounting configurations, giving it flexibility across a wide variety of lifting, pushing, clamping, and positioning applications. The 7/16-20 port size is compatible with standard hydraulic fittings and hose assemblies used in low-profile cylinder circuits. This cylinder is commonly deployed in manufacturing, maintenance, and repair operations where a full-size cylinder cannot be accommodated. It is a direct replacement or web-only SKU intended for service and parts procurement.

Key Features

• Single-acting actuation with hydraulic extend and gravity or load return
• Steel body construction for durability in industrial service conditions
• Supports horizontal and vertical mounting orientations
• 7/16-20 port size compatible with standard hydraulic fittings
• Compact form factor at 2.2 pounds for use in tight-clearance applications

Compatibility

Designed as an OEM-style replacement compact hydraulic cylinder for use in single-acting hydraulic circuits requiring a steel-body cylinder with a 7/16-20 port and horizontal or vertical mounting capability.

Installation Notes

Installation should be performed by a qualified hydraulic technician or millwright familiar with hydraulic circuit assembly and safety practices. Depressurize and isolate the hydraulic system completely before removing or installing any cylinder. Ensure all fittings are rated for the system operating pressure and that port threads are clean and undamaged before making connections. Follow applicable OSHA and equipment manufacturer guidelines for hydraulic system service.
