Bridgeport 12750605 Knee Crank Assembly Milling Machine

Product Description

The BRIDGEPORT 12750605 is a knee crank assembly designed as a replacement part for Bridgeport-style vertical knee milling machines. The knee crank is the manual elevation control that raises and lowers the knee casting along the column, directly positioning the workpiece relative to the spindle. This assembly is a core mechanical component that sees regular use in any shop environment and is subject to wear over time. Machinists, machine tool technicians, and maintenance personnel working on vertical knee mills will encounter this part during routine service and rebuild work.

This knee crank assembly is used on vertical knee milling machines in tool and die shops, machine shops, vocational training facilities, and general manufacturing environments. It applies to machines requiring manual knee elevation adjustment. This part is appropriate for shops performing in-house machine tool maintenance and rebuilding worn or damaged knee crank components to restore full manual elevation function.

Installation Notes

Installation should be performed by a qualified machine tool technician or maintenance machinist. Power down and lock out the machine at the main disconnect before beginning any disassembly. Standard hand tools are typically required for removal of the worn assembly and installation of the replacement. Verify all fasteners are properly seated and that the knee moves freely through its full travel before returning the machine to service.
