Ruland Aluminium Clamp Style Jaw Coupler 41.3 mm Outside Diameter, 14 mm Bore, 53 mm Length MJC41-14-A

Ruland MJC41-14-A aluminium clamp style jaw coupling is a robust mechanical power transmission component designed for industrial, manufacturing, and mechanical machinery applications. Featuring a 41.3 mm outside diameter, 14 mm bore diameter finished with no keyway, and 53 mm length, it provides precise shaft connection with minimal backlash.

The coupling utilizes a clamp style jaw design with two aluminium hubs and an elastomeric polyurethane spider insert which damps vibration and impulse loads. This spider reduces shock transmission to sensitive motor equipment and ensures smooth torque transfer with minimal torsional rigidity loss.

Its balanced design is suited for high bearing loads and moderate inertia, allowing for slight angular, axial, and parallel misalignments often encountered in real-world industrial environments. The spider comes in two hardness levels, with 92 Shore recommended for damping and 98 Shore for torsional rigidity, optimizing performance based on application needs.

The MJC41-14-A model supports maximum speeds up to 8000 rpm for high-speed motor shafts and power transmission systems. The snap-fit spider element guarantees zero backlash and maintains torque capabilities under dynamic conditions. Its fail-safe design lets the coupling continue operating safely even if the spider fails, enhancing system reliability.

This product complies with REACH, DIN 91 1.9, and RoHS standards, assuring quality and environmental safety. Note that a complete coupling assembly requires two hubs and a jaw spider torque disc, which must be ordered separately to build the full connection system.

Commonly used in manufacturing, mechanical machinery, fluid power systems, and industrial automation, this coupling efficiently connects rotating shafts while isolating vibrations and accommodating misalignments for longer equipment life.

Ruland’s MJC41-14-A model is manufactured in the United States under strict quality controls, emphasizing durability, precision, and industrial suitability. The clamp style jaw coupling offers high torque capacity and balanced aluminium construction.

Polyurethane spider inserts reduce shock loads and vibration. Designed to accommodate misalignments to protect machinery components. Zero backlash and fail-safe operation enhance reliability. Suitable for industrial and mechanical power transmission applications.
