Overview
The Dodge 117112 taper lock bushing is a Type 3020 mechanical coupling component engineered for industrial power transmission and motion control applications. This stock bore unit features a 1-5/8″ diameter finished bore with 3/8″ × 3/16″ keyway, designed to provide positive, wobble-free shaft engagement. Built from sintered steel, the Dodge 117112 delivers compact, flangeless design suitable for machinery, conveyor drives, gearbox input/output shafts, and industrial automation systems.
Key Features
- 8-degree taper – Grips tight, holds tight, runs true with no wobble; flush-mounted design eliminates protruding parts
- Stock bore with keyway – 1-5/8″ bore diameter, finished for immediate installation on standard shafts
- Sintered steel construction – Durable, reliable performance in high-torque applications
- Easy on/off operation – Snap-on, snap-off design simplifies installation and maintenance
- Industry-standard design – Proven 40+ year track record in industrial power transmission
