This is an authentic OEM approved replacement item commonly used on Makita power tools. Bearings have many useful applications that will differ depending on a tool. Ball bearings are designed to minimize friction between two rotating parts. Because they are under constant pressure. Over time due to heat and friction bearings would break down and would need to be replaced. Please note this is a sealed metal bearing that is sold individually.
Remove 4 gearbox mounting screws, gearbox will simply fall off. Use impact to remove pinion gear. Use small gear puller or hammer to remove motor end plate from motor shaft. Pop bearing out of plate. Install new bearing, reverse of removal.

Front bearing was bad, making lots of noise and RPM\'s were half the normal speed
Pulled front bearing off with small bearing puller. Decided to replace rear pulley also. Had to cut rear pulley with Dremel cut-off wheel. Used sockets to tap bearings back on shafts and replaced rubber O ring around the front bearing.
Disassembled sander, removed worn sealed bearings and installed new bearings. Reassembled sander and operational check was good.
As a person that repairs just about anything, it is so nice to have the correct parts to work with. So I say to the site; great job on getting me the correct parts.=ƒæì=ƒÅ+
