Product Description

Ruland MJC33-12-A Aluminium Clamp Style Jaw Flexible Coupler is engineered for industrial mechanical power transmission systems. It features a 33.3 mm outside diameter, 12 mm bore diameter, and a length of 44.5 mm, providing a robust solution for high torque transmission with minimal backlash.

This coupling comprises clamp style aluminium hubs designed for quick assembly and maximum torque handling. The inclusion of a polyurethane jaw spider insert (available in varying hardness) provides excellent shock absorption, reducing wear on connected machinery and enhancing system longevity.

The MJC33-12-A model supports rotational speeds up to 8000 rpm, suitable for use in a broad range of applications including manufacturing equipment, HVAC systems, and industrial machinery. Its balanced design accommodates slight misalignments - axial, angular, and parallel - thereby preventing excessive vibration and mechanical stress.

For a complete coupling assembly, two hubs must be used together with a suitably rated jaw spider torque disc, which must be ordered separately. The spider’s snap fit ensures zero backlash and fail-safe operation, making this product a reliable choice for demanding mechanical environments.
