VB45-PB Bearing Isolator
The VB45-PB Bearing Isolator provides permanent bearing protection for pillow blocks.
The Inpro/Seal VB45-PB™ Bearing Isolator is specifically designed for pillow block applications. Its unique design fits directly into the pillow block LER groove and solves the problem of angular misalignment by aligning precisely to the shaft and not to the housing, ensuring a perfect sealing solution for permanent bearing protection on pillow blocks.
The VB45-PB Bearing Isolator is available in two different installation methods, Pin and O-Ring Mount, to guarantee an effective sealing solution that is secure within the block, ensuring the stator doesn’t spin with the shaft.
The Pin Mount installation method uses an anti-rotation pin affixed to the Bearing Isolator to secure it to the block. This method is recommended when shaft to bore misalignment can be an issue or is unknown.
The O-Ring Mount installation method uses o-rings to secure the Bearing Isolator to the block. This method is recommended when there is minimal to no shaft to bore misalignment.
