Retainer Ring

Retainer Ring/Retaining ring/Retainer Ring segment/Retainer Ring for Hydraulic cylinder

Retainer rings are used to fasten assemblies on shafts or inside housings and bores. The ring installs into a groove to retain the assembly. Retainer rings are available in various sizes and in internal or external rings.

Retaining rings are engineered components used to hold many types of assemblies together. They are precision engineered to accurately position, locate and retain parts on shafts or in bores. The rings are installed into a groove, and all the other components of the assembly sit against and are retained by the ring.

In hydraulic systems, spiral retaining rings are used most often on the cylinder, particularly to retain the seal packing in cylinders. Retaining rings replace machined “steps” to retain the packing. Additionally, retaining rings are also found in hydraulic couplers, hydraulic pumps and other hydraulic components that need secure fastening.
