Ruland Aluminium Clamp Style Jaw Flexible Coupler 19.1 mm OD, 4mm Bore, 27.2 mm Length MJC19-4-A

Ruland MJC19-4-A is an aluminium clamp style jaw flexible coupler designed for mechanical power transmission applications requiring precise torque transfer and vibration damping. The product features a 19.1 mm outside diameter, 4 mm finished bore without keyway, and a length of 27.2 mm, offering a compact yet robust solution for coupling shafts.

Constructed from durable aluminium, this coupler provides lightweight strength and a balanced design suitable for high bearing loads and moderate inertia. It achieves zero backlash using a snap fit polyurethane spider that also effectively dampens impulse loads, reducing shock to motors and sensitive equipment.

The coupling system requires two hubs and a jaw spider to complete the assembly, which must be ordered separately. The polyurethane spider is available in two hardness levels to customize dampening and torsional rigidity, making this coupling versatile for various industrial, mechanical, and manufacturing applications.

This Flexible Coupler accommodates slight angular, axial, and parallel misalignments while maintaining high torque capacity and fail-safe operation, allowing continued function even in the event of spider element failure.

The maximum speed rating of 8000 rpm allows use in moderate to high-speed rotating machinery found in industrial power transmission, fluid power, and general mechanical uses. Clamp style jaw couplings provide high torque capacity and balanced design.

Aluminium hubs ensure a strong but lightweight coupling solution. Polyurethane spider dampens impulse loads and minimizes equipment vibration. Zero backlash design enables smooth torque transmission. Suitable for use in industrial mechanical power transmission systems.

Compatible with high-speed applications up to 8000 rpm. Requires two hubs and one jaw spider per coupling assembly (sold separately).

Ideal for industrial, manufacturing, HVAC, and fluid power equipment, this Ruland flexible coupling ensures reliable mechanical power transmission with enhanced damping and alignment tolerances. EnvMart offers this product to support your precision machine assembly needs.
