Description
Overview:
The Spiral Bevel Gear 53b is a genuine Makita replacement gear for selected angle grinders, designed to transfer drive from the motor to the output spindle smoothly and reliably. Manufactured from hardened steel for wear resistance, the spiral bevel tooth form helps reduce noise and improve torque transmission under load. This gear is engineered for accurate fit and long service life in demanding workshop and site use. It is intended for Makita GA7020 and GA7020S models and serves as a direct replacement identified by OEM No. 227489-9. Fitting a fresh bevel gear restores consistent performance, protects the gearbox from further damage, and helps maintain safe, efficient cutting and grinding operations.
