Makita 318302-3 — Bearing box (bearing housing) for angle grinders and groove cutters. This original Makita bearing box is supplied without the bearing and is the gearbox/bearing housing that supports the spindle and internal gearset.
Fits many Makita grinders and cutters — examples include the 9564 series (9564, 9564CV, 9564H, 9564PCV), 9565 series (9565, 9565CV, 9565H, 9565PCV), earlier 9562 variants and models such as SG1250/SG1251. (Check your model’s parts breakdown to confirm orientation and fastener locations.)
Sold as the bearing box only (w/o bearing); the parts diagram for these models shows the mating ball bearing (e.g., part 211129-9 / 6201 type) that you should reuse or replace when installing this housing.
This item replaces older Makita part numbers used in the same assemblies (see replacement listing for 317570-5) and is offered as a genuine Makita component to restore proper spindle alignment and gearset support. Makita spare parts like this bearing box are a common repair item to bring grinders back to safe, quiet operation.
Note: confirm the part number against your tool’s exploded parts list before ordering to ensure correct fit.
