HHR - DOUBLE ACTING HOLLOW PISTON CYLINDERS

Capacities from 33 to 247 tonnes
Stroke lengths from 50 to 305mm
Working pressure 700 Bar

The HHR double acting hollow piston cylinder range incorporates all of the design features of the HHS range with the added benefit of double acting design, which greatly enhances speed of operation and performance particularly in the longer length stroke options. Additionally a substantial hydraulic pulling force is available in the piston retraction mode of operation. Standard range models are featured in this catalogue, however other stroke and tonnage options are available on request.
