Single-Acting Cylinders - RAC

Lightweight aluminum cylinders from Enerpac in the RAC series are easy to transport and are developed with composite bearings on all movable surfaces, preventing metal-to-metal contact. Cylinders in the RAC series have a stop ring that absorbs load and the hard surface of the cylinder body protects against wear.
