Overview
The 2517 1-3/16 taper-lock bushing is a precision shaft locking device engineered for industrial power transmission applications. Used on sprockets, sheaves, and pulleys, this bushing increases clamping force beyond standard bored-to-size products that rely only on keyway and setscrew. The split-tapered design delivers flush mounting, compact footprint, and excellent grip without wobble.
Key Features
- 8° taper angle with steel construction and black oxide coating
- Split bushing design for simple installation and removal
- Finished bore with keyway slot for positive shaft drive
- Dual setscrew clamping mechanism for consistent torque
- Low-profile design fits flush into tapered hubs
