Bridgeport 11190237 Spindle Ball Bearing Milling

Product Description

The BRIDGEPORT 11190237 is a spindle ball bearing designed as a direct replacement component for Bridgeport-type milling machines. Spindle bearings support the rotating spindle assembly, maintaining precise alignment and reducing friction during cutting operations. This bearing is a mechanical wear component installed by machining technicians and maintenance professionals during scheduled spindle service or unplanned downtime repairs. At 1 pound, it is a compact, single-unit part suited for bench-level installation during spindle disassembly.

This spindle ball bearing is intended for use in Bridgeport-type vertical knee mills, specifically I Series milling machines. It fits into the spindle housing assembly and is a standard service part replaced during spindle rebuilds or when excessive runout, noise, or heat indicates bearing failure. This is a common maintenance item in machine shops, vocational training facilities, and industrial production environments operating Bridgeport-style milling equipment.

Installation Notes

Spindle bearing replacement should be performed by a qualified machinist or mechanical maintenance technician. Disconnect and lock out all power to the machine before beginning any spindle disassembly. Use a bearing press or appropriate puller to remove the old bearing and seat the new one without applying force through the rolling elements. Follow the machine manufacturer's service manual for proper preload and reassembly procedures.
