Bridgeport 12180057 Brake Bearing Cap

Product Description

The BRIDGEPORT 12180057 is a brake bearing cap designed for use on Bridgeport-type milling machines. This cap seats and retains the bearing assembly within the brake mechanism, maintaining proper alignment and protecting internal components from contamination and wear. It is a direct replacement part intended for machine shops and maintenance technicians who service vertical knee mills. Proper fitment keeps the brake system functioning correctly, which is essential for safe spindle control and accurate machining operations.

This brake bearing cap is used on Bridgeport-type vertical milling machines commonly found in job shops, tool rooms, and maintenance facilities. It is typically installed during brake assembly rebuilds or when the existing cap shows wear, cracking, or damage that compromises the integrity of the bearing seat. Maintenance machinists and millwrights perform this type of service as part of routine spindle brake overhaul work.
