Makita 210249-6 Ball Bearing 688LLU XMT04

Product Description

The MAKITA 210249-6 is a replacement ball bearing — model designation 688LLU — designed for use in Makita power tools requiring this specific bearing size and seal configuration. Ball bearings of this type support rotating shafts and spindles, reducing friction and maintaining alignment under load. This part is installed by tool repair technicians and service professionals during routine maintenance or following bearing failure. The dual-lip seal (LLU designation) retains lubrication and helps exclude debris, extending service life in demanding work environments.

This bearing is a direct replacement component for the Makita XMT04 multi-tool, where it supports internal rotating assemblies. It is typically replaced during motor or spindle rebuilds when the original bearing shows signs of wear, noise, or play. Tool service shops and field technicians performing equipment maintenance will encounter this part during disassembly of the drive train or spindle housing.

Installation Notes

Bearing replacement should be performed by a qualified tool repair technician. Disconnect and fully de-energize the tool before disassembly. Use a proper bearing press or appropriate driver set to remove the old bearing and seat the replacement — never strike the bearing directly with a hammer. Follow the tool manufacturer's service documentation for correct assembly sequence and torque guidance.
