PMR Bearing Isolator

The PMR Bearing Isolator provides permanent bearing protection to paper machine rolls.

The Inpro/Seal PMR Bearing Isolator utilizes an integral heavy duty flinger that rotates with the shaft and provides high performance bearing protection by knocking away moisture and other contaminants while also creating a tortuous path against contamination ingress. For use in heavy washdown environments, a large expulsion port allows for large amounts of moisture or other contaminants to be expelled through the seal into atmosphere.

This unique design allows for axial growth and up to 0.500 in. of radial movement and can also be engineered to accommodate angular movement.
