Makita 318303-1 Bearing Box Cover for Sander LXOB01 LXOB01Z (Type1-2)

The Makita 318303-1 Bearing Box Cover is an OEM replacement protective hardware component specifically engineered for Makita’s line of cordless random orbit sanders. Positioned at the base of the tool's motor housing, this critical cover encloses and secures the main bearing assembly, shielding the high-RPM rotational components from fine, abrasive wood flour and drywall dust. Because random orbit sanders rely on a rapid spinning and eccentric wobbling motion to smooth surfaces, any dust ingress can quickly freeze the bearing, overheat the motor, or cause intense tool vibration. Replacing a cracked, warped, or worn factory cover restores the tool's airtight internal seal, stabilizes the sanding pad assembly, reduces operator hand fatigue, and ensures long-lasting, smooth sanding performance on the jobsite. Makita 318303-1 Bearing Box Cover is specifically engineered for Makita 18V LXT® Cordless 5-Inch Random Orbit Sanders LXOB01 and LXOB01Z.
