Overview
The Martin 2517-2-1/8 taper bushing is a standard taper lock bushing designed for reliable mounting of pulleys, sheaves, sprockets, and gears on drive shafts. This bushing is made of sintered steel and features flush mounting for reduced mounting width with a split taper for a tight clamp to shafts. The 2-1/8 inch bore accommodates shafts in this size range, while the 8-degree tapered construction ensures positive drive transmission with excellent holding power.
Key Features
- Sintered powder steel construction offers greater strength and wear resistance than plain carbon steel
- Flush mounted design with split taper for tight shaft clamping and reduced mounting width
- Keyed to the shaft to prevent rotation and interchangeable with taper bushings from various manufacturers
- 8-degree taper angle for consistent, reliable power transmission
- Split design enables easy installation and removal, minimizing maintenance downtime
- Manufactured to meet ANSI, NAS, and DIN standards

Typical Applications
This taper bushing is used in automobiles, construction equipment, agricultural machinery, and home appliances. The bushing is particularly used in the manufacturing, agricultural, and material handling industries, where optimal performance and durability are critical. Bushings are cylindrical parts used to mount pulleys, sheaves, sprockets, or other components to drive shafts for transmission of mechanical power. Most bushings are split and have a tapered outside surface so they clamp to the shaft when tightened against the tapered bore of the driven component.
