Increase Motor Reliability by Extending Bearing Life

The Importance of Bearing Protection

Bearings are a critical component to electric motors and are designed to operate for many years. Yet, more than half of motor failures are caused by bearing failure due to ineffective bearing protection from contamination ingress, lubrication loss and stray shaft currents. Extend bearing life with superior bearing protection from Inpro/Seal.

Motor Application Solution

The High Cost of Contact Seals

Contact seals, such as lip seals, are commonly used on motors to seal the bearing housing. Yet, due to their contacting nature, they wear at the point of contact or groove the shaft, rendering them ineffective in a short period of time. This allows lubrication to escape and contamination to enter the bearing housing, leading to premature bearing failure.

A Permanent Sealing Solution

For over 40 years, the Inpro/Seal Bearing Isolator has been increasing motor reliability with permanent bearing protection against contamination ingress and lubrication loss. The Inpro/Seal Bearing Isolator is a non-contacting compound labyrinth seal that significantly increases mean time between repair (MTBR) and decreases maintenance costs.
