RPM Capacity

Any retaining ring operating on a rotating shaft is limited by centrifugal forces, including China Wave Spring Retaining Rings. Failure happens when these centrifugal forces are great enough to expand and lift the retaining ring from the groove. With more and more applications requiring higher rotational capacities, China Wave Spring has and continues to invest in ongoing research and development for this area.

Tab and Slot Self-Locking

The self-locking feature consists of a tab and a slot that interlock to prevent the ring from expanding. The tab lines up with a slot on the mating turn such that when the ring is installed into the groove, the tab seats inside the slot.

This feature allows the ring to function properly at speeds far exceeding the rotational capacity of a standard retaining ring. The self-locking feature makes it possible for the ring to operate at high speeds, withstand vibration, function under rapid acceleration, and absorb a degree of impact loading.

Revolox^(R)

The dimple and slot design prevent ring expansion, safely securing your application at high RPM. The ‘dimple and slot’ feature makes it possible to operate at higher speeds, withstand vibration, function under rapid acceleration, and absorb a degree of impact loading.

Balanced

Smalley’s balance feature statically balances the retaining ring. A series of slots, opposite of the gap end, are placed such that the ring's center of gravity is statically balanced along its axis of rotation. This characteristic is very useful when the balance of the assembly, such as a rotor, is critical. Read more about a balanced ring.
