Product Description
Martin - Jaw Coupling Half (ML Series)
Martin Sprocket & Gear — 520 Configurations
Overview
Specifications
Applications
Martin couplings connect rotating shafts while accommodating misalignment, absorbing shock loads, and dampening vibration between the driver and driven equipment. Whether you’re connecting a motor to a pump, gearbox to a conveyor, or any other power transmission application, the right coupling protects both components from the forces that cause premature bearing failure, shaft fatigue, and seal leaks.
Martin Sprocket & Gear has been manufacturing couplings and power transmission components in the USA since 1928. Their coupling line includes jaw couplings, Quadra-Flex® elastomeric couplings, and gear couplings — each designed for specific torque ranges, misalignment tolerances, and operating conditions.
Available in 520 configurations (ML-ML090-1/4, ML-ML090-5/16, ML-ML090-3/8, ML-ML090-10MM, ML-NA1 and 515 more) for professional power transmission applications.
- Misalignment Accommodation — handles angular, parallel, and axial shaft misalignment
- Shock Absorption — elastomeric elements dampen vibration and protect connected equipment
- Easy Maintenance — replace flex elements without moving motors or driven equipment
- Multiple Bore Options — available in standard and metric bore sizes with keyways
- USA Heritage — Martin Sprocket & Gear, manufacturing since 1928
