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.
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.

Proven Shaft Grounding Technology
Variable Frequency Drives (VFDs) induce high-frequency voltages on the shaft that discharge through the bearings, leading to bearing failure. Inpro/Seal Smart Shaft Grounding diverts harmful shaft currents away from the bearings to ground, providing long lasting bearing protection for VFD-driven motors.
