The Enerpac CSM27251 is a single-acting, spring-return manifold cylinder from the CSM series. It screws into a standard SAE #20 (1-5/8"-12 UN) port cavity machined in your fixture, so oil is fed through the fixture body with no external tubing. It delivers 6,110 lb at 5,000 psi over a 0.98 in stroke.
Features
- Installs in a standard SAE port cavity for a clean, tube-free fixture
- Center-tapped plunger (.375-16 UN) for contact buttons and attachments
- Spring return
- Very compact for multi-cylinder fixtures
Sizing
Effective area is 1.22 in² and a full stroke uses 1.20 in³ of oil. Overall length is 3.27 in retracted and 4.25 in extended; weight 2.0 lb. Workholding circuits often run below 5,000 psi; at 2,000 psi this cylinder gives about 2,440 lb of force and at 3,000 psi about 3,660 lb.
How it compares
Same SAE #20 cavity, different stroke: CSM27151 (0.59 in).
Before you order: Check the installation dimensions for the SAE #20 (1-5/8"-12 UN) cavity in the Enerpac catalog before machining; the spring needs at least 580 psi to overcome.
