Bridgeport 12193544 Feed Bevel Pinion Assembly

Product Description

The BRIDGEPORT 12193544 is a feed bevel pinion assembly designed for use in Bridgeport-style milling machines. The bevel pinion is a critical drivetrain component in the knee mill feed mechanism, transmitting rotational motion through the table or knee feed system. This part is typically replaced by a machinist or millwright during routine maintenance or when wear causes slippage, noise, or loss of feed motion. It is a direct mechanical component, not an electronic or fluid-carrying part, and requires basic hand tooling and knowledge of milling machine disassembly to install correctly.

This assembly is suited for use in vertical knee milling machines that use a bevel gear feed drive system. It is commonly encountered in job shops, toolrooms, and light manufacturing environments where Bridgeport-type mills are in service. Technicians replacing worn or damaged feed components should verify the assembly matches the specific machine generation and feed axis before installation.

Key Features

• Feed bevel pinion assembly for milling machine feed drive systems
• Sold as a complete assembly unit, not individual loose components
• OEM Bridgeport part number for direct replacement fitment
• Applies to table, saddle, or knee feed mechanisms depending on installation position

Compatibility

Designed as an OEM-style replacement feed bevel pinion assembly for Bridgeport-type vertical knee milling machines. No specific compatible model numbers were provided in the product data. Verify fitment against your machine serial number and parts manual before ordering.

Installation Notes

Installation is typically performed by a machinist or millwright with experience in manual milling machine service. Power down and lock out the machine at the main disconnect before disassembling any feed mechanism components. Proper fit of bevel gear components requires careful alignment to avoid premature wear or backlash issues. Consult the machine manufacturer service manual for disassembly sequence and reassembly torque guidance specific to your model.
