The double-acting hollow piston cylinders of the HHR series offer all elements of the HHS series, but have the additional advantage of double-acting operation, which significantly increases operating speeds and performance, especially in applications with larger strokes. In addition, considerable hydraulic pulling force is also available when operating in piston retraction mode.
