Enerpac CST9131 Compact Hydraulic Cylinder Steel

Product Description

The ENERPAC CST9131 is a single-acting compact hydraulic cylinder built for installations where space is limited but reliable force output is required. Constructed from steel, this cylinder is suited for use in industrial maintenance, shop press, and general hydraulic tooling applications. The single-acting design relies on hydraulic pressure for extension and an external force or spring for retraction. The 7/16-20 port size is compatible with standard hydraulic hose fittings used in low-profile cylinder setups. Hydraulic technicians and maintenance professionals working on industrial equipment, tooling fixtures, or portable hydraulic systems will find this cylinder a direct-fit replacement option.

The CST9131 supports both horizontal and vertical mounting orientations, giving installers flexibility in how the cylinder is positioned within a system. This makes it practical for a range of fixture and press applications where the load direction may vary. The steel body construction handles the demands of shop and industrial environments where durability under cyclic hydraulic pressure is a priority.

Key Features

• Single-acting actuation — hydraulic pressure extends, external force or spring retracts
• Steel body construction for durability in industrial and shop environments
• Supports horizontal and vertical mounting orientations
• 7/16-20 port size compatible with standard hydraulic fittings
• Compact form factor suited for tight-clearance installations

Compatibility

Designed as an OEM-style replacement compact hydraulic cylinder for single-acting hydraulic systems 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. Depressurize the hydraulic circuit completely and relieve all stored pressure before disconnecting or connecting any hydraulic components. Ensure the mounting surface and orientation are appropriate for the load direction and that all fittings are tightened to the hydraulic system specifications. Do not exceed the rated operating pressure of the cylinder as specified in the manufacturer documentation.
