An Internal retaining ring, also known as an internal snap ring is a type of fastening device used in piston motors to secure various components in place. It is designed to fit into a groove or recess on the inner diameter of a cylindrical bore or shaft, holding the components securely. It consists of a thin, flat, circular metal ring with a small gap or opening. This opening allows the ring to be expanded or contracted for installation or removal.Attributes:• Provide strength and durability.• Designed to resist corrosion.• Withstand vibrations and rotational forces.Applications: An Internal retaining ring helps to maintain proper alignment and ensures the efficient operation of the motor.
