Self-Locking Retaining Rings

Self-Locking Retaining Rings are ideal for applications that have high rotational requirements. This feature allows the ring to function properly at speeds that exceed the recommended rotational capacity. The self-locking option can be incorporated for both external and internal rings. The self-locking feature utilizes a dome on the inside turn “locking” into a slot on the outside turn.

Self-locking allows the ring to operate at high speeds, withstand vibration, function under rapid acceleration, and absorb a degree of impact loading.

Revolox^® Self-Locking Rings for High RPM

From electric motors to transmissions, the Revolox Self-Locking Ring from Smalley is engineered with your high rotational capacity applications in mind. The revolutionary retaining ring enables engineers to design around high RPM requirements safely, easily, and with ease of assembly for high production volumes. 

The 'dome and slot' design prevents ring expansion, safely securing your application at high RPM. This makes it possible to operate at higher speeds, withstand vibration, function under rapid acceleration, and absorb a degree of impact loading.

Tab and Slot Self-Locking Retaining Rings

• Easy visual verification of proper installation
• Available in heavier cross-sections of wire

Centerline Locking Feature

• Self-Locking feature is found in the center and therefore not allowed to interfere with mating components
• Prevents misalignment of the ring underside loading
• Installation is manual and once installed the rings become tamper-proof. Removal requires the installation of a new ring.
