Ultra-Flat cylinders designed for big lifts in small spaces

With a 700 bar max operating pressure, the Ultra-Flat cylinders provide a 7–17mm stroke, and are designed to withstand up to 4% side load at full lifting capacity. The CUSP-Series has an integrated tilting function up to 4°, and a 6–10mm tilted stroke.                               

Safety is critical to all Enerpac products. CULP Ultra-Flat hydraulic cylinders are equipped with an internal stop ring that prevents the plunger from accidentally dropping at the end of its stroke. CUSP Cylinders have a ‘Red Line’ as visual indicator to the operator when the maximum stroke has been reached.

The CUSP-Series’ tilting plunger can be adjusted enabling equal distribution of load over its full surface. Even at maximum tilted position, most models will have a straight lifting stroke of 10mm.


All Enerpac cylinders are built to last. In addition to low maintenance requirements, the Ultra-Flat hydraulic cylinders feature a nitro carburising surface treatment providing greater load and wear resistance, as well as, corrosion protection in the harshest working conditions.

The CULP-Series and CUSP-Series Ultra-Flat hydraulic cylinders can be used with Enerpac hydraulic pumps - available in over 1000 different configurations – whatever the application’s requirements for speed, control, intermittent or heavy duty.
