CUSP50 550 kN Capacity, 10 mm Stroke, High Tonnage Ultra Flat Hydraulic Cylinder

Enerpac CUSP50 is a robust single-acting high tonnage ultra flat hydraulic cylinder designed for heavy-duty lifting in confined spaces during industrial maintenance, construction, and precise load positioning tasks. Delivering a 62 US ton (550 kN) advance capacity over a 10 mm stroke, this model ensures even load distribution with an integrated tilting function up to 4 degrees, operating at up to 10,150 psi with up to 4% side-load resistance, nitrocarburized surfaces for cyclic wear, and protection for reliability in harsh environments.
