PTFE Bearing Isolator

Bearing Isolator (Bearing Protector) is a kind of non-contact, non-wearing, permanent bearing protection device.

It consists of a rotor and a stator, which are unitized by an O-ring, so that the two parts will not be separated during the operation.

The two components interact to keep thepollutants out of the bearing housing and prevent the leakage of the lubricants . The sealing performance of the Bearing Isolator will not degrade over time, which will enable it to provide life-time bearing protection for the rotating equipment.

Features & Benefit

High-performance, non-contact design eliminates fretting caused by lip seals

Keeps lubrication in and seals out external contamination

Unitized design and durable, non-sparking material provide easy, reliable installation

Soft materials guarantee no damage to shaft and the Isolator itself in high vibrating condition
