Bridgeport 12190203 Bevel Pinion Gear Milling Machine Part

Product Description

The BRIDGEPORT 12190203 is a bevel pinion gear designed as a replacement component for Bridgeport milling machines. Bevel pinion gears transmit rotational force between intersecting shafts, typically at a 90-degree angle, and are critical to the quill feed and table traverse mechanisms found in knee-style vertical milling machines. This part is sourced as an OEM-style replacement to restore proper gear engagement and smooth mechanical operation. Installation is performed by qualified machine tool technicians or maintenance machinists during scheduled overhaul or corrective repair of the milling machine drivetrain.

This bevel pinion gear is suited for use in machine shop environments where Bridgeport-style knee mills are in service. It fits within the gear train assemblies that control powered table or quill movement. Maintenance intervals, worn gear teeth, or damaged gear faces are common reasons this component is replaced. It is packaged individually and sold as a single unit.

Key Features

• Bevel pinion gear profile for intersecting-shaft torque transfer in milling machine drivetrains
• OEM-style replacement geometry for direct fitment into Bridgeport-style milling machines
• Single-unit packaging for targeted repair without excess inventory
• UNSPSC Code 23242100 classification confirming machine tool component category

Compatibility

Designed as an OEM-style replacement bevel pinion gear for Bridgeport-style knee milling machines. No additional specific model compatibility data was provided in the product information.

Installation Notes

Installation should be performed by a qualified machine tool technician or industrial maintenance mechanic. Disconnect and lock out all electrical power to the milling machine before disassembling any gear train or drivetrain components. Inspect mating bevel gears, shafts, and retaining hardware for wear before reassembly. Follow the machine manufacturer service documentation for proper gear seating, backlash adjustment, and lubrication procedures.
