Description
Overview:
The Makita Ball Bearing 6203DDW (M9001) is a genuine Makita component (MPN 211285-5) used to support and guide rotating parts inside angle grinders. Built from hardened bearing steel with double rubber seals, it helps keep out dust and debris while holding factory grease in place for smooth, efficient running. This bearing reduces friction and vibration, protecting the motor and gearbox and helping the tool run quietly and reliably. It is commonly used on Makita angle grinders such as the GA7020 and GA9020, and is suitable for routine maintenance or to replace a worn, noisy, or rough-running bearing. Fitting a correct, genuine bearing restores clearances and performance, helping to reduce heat build-up and extend the service life of your grinder.
