Overview
The Martin 3020-2-15/16 taper bushing is a standard taper lock bushing engineered for reliable mechanical power transmission in industrial applications. Featuring a 2-15/16 in bore with a 3/4 x 3/8 in keyway and steel material construction, this split-taper design provides the clamping force needed to securely mount taper-bored components on drive shafts.
Key Features
- Split-taper construction utilizing screws to tighten on the shaft, providing excellent clamping force
- Flush mounted for reduced mounting width with split taper for tight clamp to shafts
- Steel material for durability in demanding mechanical applications
- Keyed to shaft to prevent rotation in the bushing; interchangeable with taper bushings from various manufacturers
- Used on sprockets, sheaves and pulleys to increase clamping force over standard bored-to-size product that only utilizes a keyway and setscrew
Technical Specifications
This bushing meets industry standards for taper lock mountings across general industrial equipment and power transmission systems.
Typical Applications
The Martin 3020 taper bushing is used in automobiles, construction equipment, agricultural machinery, and home appliances. Bushings are cylindrical parts used to mount pulleys, sheaves, sprockets, or other components to drive shafts for transmission of mechanical power, with most bushings split and having a tapered outside surface so they clamp to the shaft when tightened.
