A Spiral Retaining Ring used in Torque Converters and Retarders is placed into a groove on a shaft creating a shoulder that retains a unit and their spiral shape allows them to expand and contract as needed to fit into the groove.

Attributes:
• Prevents the part from becoming dislodged during operation
• Manufactured to precise specifications and are built for durability and reliability

Applications:
A Spiral Retaining Ring is tasked with the retention of the associated parts by implementing kinematic constraints in the system. This is usually installed on the outer diameter of a shaft.
