The Enerpac CUSP500 is a 500-ton class ultra-flat, single-acting, load-return cylinder from the CUSP-Series, with a maximum capacity of 574.8 tons at 10,150 psi and a collapsed height of just 3.25 in. Its integrated tilting function (up to ±2°) 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 ±2° to distribute the load evenly
- Nitrocarburized surface treatment for harsh conditions
- "Red Line" for visual maximum stroke indication
- CR400 coupler with dust cap
Sizing
Stroke is 0.60 in straight and 0.39 in when tilted. Effective area is 113.24 in² and a full stroke needs 67.77 in³ of oil. The CUSP500 is 3.25 in collapsed, 3.85 in extended, 14.02 in outside diameter and weighs 138.2 lb.
How it compares
Nearby capacities in the CUSP range: CUSP300 (300 ton, 2.85 in collapsed), CUSP400 (400 ton, 3.05 in collapsed), CUSP600 (600 ton, 3.44 in collapsed), CUSP750 (750 ton, 3.68 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 HC-Series hose with CH604 coupler to connect to your pump.
