The Enerpac CUSP50 is a 50-ton class ultra-flat, single-acting, load-return cylinder from the CUSP-Series, with a maximum capacity of 61.8 tons at 10,150 psi and a collapsed height of just 2.24 in. Its integrated tilting function (up to ±4°) evens out the load when the lifting surface is not perfectly parallel, so it fits into tight gaps for machinery lifting, leveling and structural jacking.
Features
- Up to 4% side-load of maximum capacity
- Extremely low collapsed height
- Integrated tilting function up to ±4° to distribute the load evenly
- Nitrocarburized surface treatment for harsh conditions
- "Red Line" for visual maximum stroke indication
- AR630 coupler with dust cap
Sizing
Stroke is 0.52 in straight and 0.39 in when tilted. Effective area is 12.17 in² and a full stroke needs 6.37 in³ of oil. The CUSP50 is 2.24 in collapsed, 2.77 in extended, 5.12 in outside diameter and weighs 12.3 lb.
How it compares
Nearby capacities in the CUSP range: CUSP20 (20 ton, 1.59 in collapsed), CUSP30 (30 ton, 1.67 in collapsed), CUSP75 (75 ton, 2.38 in collapsed), CUSP100 (100 ton, 2.50 in collapsed).
Before you order: CUSP cylinders do not have a stop-ring for stroke limitation; ultra-flat cylinders need a solid lifting surface, as use on sand, mud or dirt can damage the cylinder; use an HB7206 hose with AH630 coupler to connect to your pump.
