Overview
The Martin 3535 1 15/16 taperlock bushing is a precision-engineered shaft-mounting component designed for mounting pulleys, sheaves, and sprockets onto drive shafts. Manufactured by Martin Sprocket & Gear, a leader in power transmission solutions since 1951, this bushing combines durability with ease of installation and removal. The split tapered design clamps securely to the shaft while maintaining a compact, flush-mounted profile.
Key Features
- Class 30 gray cast iron construction resists wear, galling, and corrosion
- Split taper design (8° included angle) for secure grip with minimal mounting width
- Flush-mounted profile eliminates protruding parts
- Finished bore with keyway for precise shaft alignment
- ANSI, NAS, and DIN standards certified
- Interchangeable with equivalent taper bushings from other manufacturers
