Description
The HHR double-acting hollow piston cylinder series builds on the core features of the HHS range, with the added advantage of a double-acting configuration. This design significantly improves operational speed and efficiency, especially for applications requiring longer stroke lengths. It also provides strong hydraulic pulling force during the retraction phase. While standard models are listed here, additional capacities and stroke lengths can be provided upon request.
