CULP50 550 kN Capacity, 6 mm Stroke, Ultra Flat Hydraulic Cylinder with Stop Ring

Enerpac CULP50 is a robust single-acting ultra flat hydraulic cylinder with stop ring 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 6 mm stroke, this model ensures safe stroke limitation independent of hydraulic pressure, operating at up to 10,150 psi with 4% side-load resistance, nitrocarburized surfaces for cyclic wear, and weather protection for reliability in harsh environments.
