Overview
Martin 2517 1 7/16 taper-lock bushings are precision-engineered components used to mount pulleys, sheaves, and sprockets on drive shafts. Made of sintered steel, these bushings are used for mounting a taper bushed pulley, sheave, or sprocket on a drive shaft. The bushing is made of sintered powder steel for greater strength and wear resistance than plain carbon steel. The 2517 series combines split tapered design with keyway construction to create a secure, adjustable interface suitable for demanding mechanical power transmission systems.
Key Features
- Flush mounted design for reduced mounting width with split taper for a tight clamp to shafts
- Sintered powder steel construction provides greater strength and wear resistance
- Keyed to the shaft to prevent shaft rotation in the bushing
- Standard split bushing design with two pull-up screws for easy on-shaft tightening
- Interchangeable with taper bushings from various manufacturers
Technical Specifications
The Martin 2517-1-7/16 bushing is engineered to tight tolerances for reliable performance across multiple industrial sectors.
Typical Applications
This taper bushing is used in automobiles, construction equipment, agricultural machinery, and home appliances, as well as general industrial conveying and power transmission systems. Used on sprockets, sheaves and pulleys to increase clamping force over standard bored-to-size product that only utilizes a keyway and setscrew to lock onto the shaft.
