Abstract
A novel and improved puller that provides a safe and efficient manner and tooling to remove bearings, bushings, gears, etc. The invention is simple and highly efficient is its design and use due to incorporating multiple design elements into the main collets or bearing adapters. My present invention uses a simple split collet machined accurately to precisely fit the bearing being removed, in addition the same collet incorporates an upper threaded section to allow the removal sleeve to easily and precisely fit to the collet while at the same time the threaded removal sleeve securely keeps the collet together and properly aligned with the bearing and shaft axis to provide easy and accurate operation. Another design integrated into my puller is the ball thrust bearing on the end of the pressure or removal screw. This anti-friction thrust bearing eliminates undue friction and provides very free rotation of the pressure screw.
