The Enerpac CSM1071 is a single-acting, spring-return manifold cylinder from the CSM series. It screws into a standard SAE #12 (1-1/16"-12 UN) port cavity machined in your fixture, so oil is fed through the fixture body with no external tubing. It delivers 2,590 lb at 5,000 psi over a 0.28 in stroke.
Features
- Installs in a standard SAE port cavity for a clean, tube-free fixture
- Center-tapped plunger (.312-24 UN) for contact buttons and attachments
- Spring return
- Very compact for multi-cylinder fixtures
Sizing
Effective area is 0.50 in² and a full stroke uses 0.14 in³ of oil. Overall length is 1.87 in retracted and 2.15 in extended; weight 1.1 lb. Workholding circuits often run below 5,000 psi; at 2,000 psi this cylinder gives about 1,000 lb of force and at 3,000 psi about 1,500 lb.
How it compares
Same SAE #12 cavity, different stroke: CSM10131 (0.51 in), CSM10191 (0.75 in).
Before you order: Check the installation dimensions for the SAE #12 (1-1/16"-12 UN) cavity in the Enerpac catalog before machining; the spring needs at least 580 psi to overcome.
