7W-6952: 137.16mm Outer Diameter Piston Retaining Ring

A Piston Retaining Ring, also known as a Piston Ring is used to securely hold a piston in place within a cylinder or a shaft by exerting radial pressure against the cylinder walls or the shaft groove. The design of a piston retaining ring typically consists of a circular or semicircular shape, made from a rigid and durable material. Attributes: • Reduce friction and ensure efficient energy transfer • Designed to withstand high temperatures, extreme pressures, and cyclic loading Applications: A Piston Retaining Ring is used to prevent the piston from moving excessively within the cylinder or shaft.
