Makita 211311-0 Ball Bearing 6304LLB

Product Description

The MAKITA 211311-0 is a replacement ball bearing, identified by the bearing designation 6304LLB. Ball bearings of this type are used to reduce rotational friction and support radial loads within power tool drive assemblies and motor housings. The 6304LLB designation indicates a standard 6304-series deep groove ball bearing fitted with dual non-contact rubber seals on both sides, which keep lubrication in and contaminants out. This bearing is a genuine Makita replacement part, designed to restore proper function to tools that have developed spindle play, excessive noise, or motor shaft wobble due to bearing wear.

This bearing is commonly installed in Makita power tools and outdoor power equipment, including lawn and garden equipment where motor or drive shaft bearings are subject to continuous rotational stress and exposure to debris. Technicians replace bearings of this type during routine motor rebuilds, after failure indicated by grinding noise or shaft play, or as part of a preventive maintenance schedule on high-hour equipment. The 6304LLB fits applications requiring a sealed bearing in the 6304 size class.

Key Features

• 6304LLB deep groove ball bearing with dual rubber seals for contamination resistance

Compatibility

Designed as a genuine OEM-style replacement ball bearing for Makita power tools and lawn and garden equipment utilizing a 6304LLB-series bearing in the motor or drive assembly.

Installation Notes

Bearing replacement should be performed by a qualified service technician familiar with power tool or small engine repair. Disconnect and de-energize the tool or equipment fully before disassembly. Use a proper bearing puller and press to remove the worn bearing and seat the replacement without applying force through the rolling elements. Follow the equipment manufacturer's service manual for disassembly sequence and fastener specifications.
