Electric Vehicles

Because of the high RPM of the EV bearing, the self-locking ring is used to resist expansion due to centrifugal force and keep it seated in its groove. These self-locking rings work by having a small tab that “locks” into an opposing slot. Without the self-locking feature, the ring could potentially grow in diameter whilst spinning, to the point that it would slip out of the groove, leading to a failure.

The same spiral ring can also be statically balanced to reduce the vibration in the motor. Maximum static imbalance requirements dictated by the customer are achieved by removing material with cut-out slots positioned opposite the ring’s gap. These slots centralize the ring’s center of gravity by compensating for the material missing at the gap.

Having a self-locking feature and balanced slots in the same spiral ring is not mutually exclusive. Some applications may just require a self-locking ring to keep the ring in the groove but not need it to be balanced. Whilst other applications may need the ring to be balanced but not require self-locking. This condition is often found where housing rings are used in high-speed rotation applications. The ring may need to be balanced to reduce the vibration in the application, but the housing constrains the ring from growing outward due to centrifugal force.

Quality Above All

Our belief in quality is reflected in every process we employ and every product we produce. Our vertically integrated manufacturing process allows for unparalleled quality control starting with the raw material, tool design and production, manufacturing equipment and processes, to the finished product.
