Milwaukee 14-46-5311 Ball Bearing Rotary Seal Assembly

Product Description

The MILWAUKEE 14-46-5311 is a ball bearing and rotary seal assembly designed as a replacement component for Milwaukee power tools. This assembly combines a precision ball bearing with a mating rotary seal to maintain proper shaft alignment, reduce friction, and prevent contamination from dust, debris, and moisture inside the tool housing. It is typically serviced during tool rebuilds or preventive maintenance when wear, noise, or excessive play is detected at the spindle or motor shaft. Installation is performed by qualified power tool repair technicians.

This assembly is suited for use in Milwaukee power tool applications where the original bearing or rotary seal has reached end of service life. It is installed during bench-level repairs on Milwaukee corded or cordless tools that share this bearing specification. Technicians performing tool rebuilds or warranty-adjacent repairs source this part as a direct OEM-replacement component to restore factory performance.

Key Features

• Combined ball bearing and rotary seal in a single assembly for efficient replacement
• OEM Milwaukee part ensuring dimensional and performance compatibility with original specifications
• Rotary seal helps exclude contaminants from the bearing cavity during tool operation
• Supports proper shaft alignment and reduces rotational friction at the bearing journal

Compatibility

Designed as an OEM replacement ball bearing and rotary seal assembly for Milwaukee power tools. Consult Milwaukee documentation or a Milwaukee-authorized service center to confirm fitment for a specific tool model before installation.

Installation Notes

This part should be installed by a qualified power tool service technician. Disconnect and de-energize the tool completely, and remove the battery pack if applicable, before disassembly. A bearing press or appropriate driver set is typically required to seat the bearing assembly without damaging the races or seal. Follow Milwaukee service documentation for proper torque and reassembly sequence.
