Overview
The Dodge 3535X378 Taper-Lock Bushing is a premium shaft-mounting component engineered for power transmission systems in manufacturing, conveyor, and motion control applications. With a 3-7/8″ finished bore and integrated keyway, the 3535X378 provides secure, precise engagement on rotating shafts with no wobble or movement. An industry standard for over 40 years, Dodge Taper-Lock bushings combine proven sintered steel technology with ductile iron construction to deliver superior durability in high-torque, high-speed environments.
Key Features
- 8° Taper Design: Wedges inward to grip the shaft tightly with consistent, reliable holding force
- Flush Mounting: No protruding parts; installs seamlessly into hubs, sprockets, and pulleys
- Easy On/Easy Off: Tool-free removal using only the setscrew holes as jackscrews—no puller required
- 3-Bolt Assembly: 4.83 inch bolt circle with 1/2 × 1-1/2 inch screw fastening
- 44,800 lbf Torque Rating: Suitable for demanding power transmission applications
