This Enerpac RACH-206 single-acting aluminum hydraulic cylinder with 20-ton capacity has a hollow plunger with a 5.91" stroke length and is suitable for use in applications where the need for push and pull forces might alternate, such as testing, maintenance, and tensioning applications. The single-acting hydraulic cylinder uses liquid pumped through its single port for rod extension and a high-strength internal spring for rod retraction to produce continued movement. A built-in stop ring prevents the plunger from extending beyond the stroke length and can endure the full capacity of the cylinder. The cylinder body is round with integrated handle and is made of lightweight aluminum with a hard-coat finish for durability and extended life. Composite bearings increase side load resistance and reduce wear. The center tube floats to extend the life of the seals. The included removable saddle is made of hardened hollow steel and bolts onto the cylinder to protect the plunger during lifting operations. The cylinder attaches to the included steel baseplate and saddle to help prevent load-induced damage.

Enerpac manufactures high-pressure tools and equipment for industrial applications. The company, founded in 1910, is headquartered in Menomonee Falls, WI.
