Bearing Removal & Extraction Tools

The use of makeshift bearing installation tools and methods can result in several expensive unintended consequences. At its worst, the misapplication of force can result in significant damage to both the bearing and the housing. At best, parts are subjected to unnecessary stresses that could potentially shorten their serviceable life requiring more frequent maintenance cycles and increased potential for unexpected failure. Designed to meet OEM specifications these risks are easily avoidable with the use of appropriate staking, swaging, cutting tools and proof load testers.

CUTTING TOOLS

Equally important as proper installation, is the correct removal of the bearing. Cutting tools are designed to remove a specific bearing with minimum damage to the housing assembly, saving the added expense of reworking the housing. Cutting tools are available in drill press or portable type. We have added the standard interchange chart for Mil-B-81820 Bearings below.
