Description
The Feed Drive Shaft Gear (Model B-363840) is a critical rotating component used in the auto-feed mechanism of vertical turret and Bridgeport-type milling machines.
This assembly includes:
- A hardened alloy-steel shaft,
- Multiple precision-cut spur gears,
- A ground bearing journal for smooth rotation,
- Correctly spaced gear sections for perfect meshing and alignment.
The shaft delivers rotary motion from the transmission gear set to the table feed system, enabling consistent and accurate feed movement.
Its rugged construction makes it suitable for heavy-duty milling operations and continuous industrial use.
Features:
- Hardened alloy-steel construction
- Factory-cut spur gears for accurate feed transmission
- Precision ground ends for perfect bearing fitment
- Highly durable and wear-resistant
- Smooth, vibration-free motion
- Direct replacement for B-363840 shaft assemblies
- Compatible with most M1TR/Bridgeport-type machines
Applications:
- Vertical Turret Milling Machine Feed Box
- Bridgeport-type Milling Machine Auto-Feed System
- Repair and maintenance of milling machine feed mechanisms
