Ruland Aluminium Clamp Style Jaw Flexible Coupler, 33.3 mm Outside Diameter, 10 mm Bore, 44.5 mm Length, Maximum MJC33-10-A

Ruland MJC33-10-A aluminium clamp style jaw flexible coupler features a 33.3 mm outside diameter, 10 mm bore, and 44.5 mm length, suitable for diverse mechanical power transmission applications. The coupling is constructed from aluminium which offers durability, corrosion resistance, and a lightweight profile, making it ideal for industrial use where reducing weight is beneficial.

This clamp style jaw coupling is designed for high torque capacity and a balanced mechanical arrangement. The assembly requires two aluminium hubs and a polyurethane jaw spider (torque disc) placed in between, which must be purchased separately to complete the coupling assembly. The jaw spider absorbs shocks and dampens impulse loads, protecting motors and sensitive equipment from sudden jolts.

The finish bore type without keyway supports precise shaft fitment, accommodating slight angular, axial, and parallel misalignments without backlash, ensuring smooth mechanical power transmission. The coupling’s maximum allowed speed is 8000 rpm.

Features of this coupling include an electrically isolating design that prevents current flow between connected parts, a fail-safe mechanism that permits operation even if the elastic insert fails, and options for polyurethane spider hardness to tailor damping or torsional rigidity.

This product complies with REACH, RoHS, and DIN 91 1.9 standards and is manufactured in the United States, ensuring quality and regulatory adherence. Manufactured from lightweight, corrosion-resistant aluminium. Clamp style jaw couplings provide zero backlash operation.

Polyurethane spider (torque disc) minimizes shock and vibration. Balanced design suited for high bearing load use cases. Accommodates slight shaft misalignments for flexibility. Electrical isolation protects connected machinery.

Fail-safe design allows operation during spider element failure. Ideal for industrial, manufacturing, power transmission, and fluid power systems.

Two hubs and an appropriate jaw spider must be ordered separately to complete a coupling assembly. This coupling is recommended for industrial mechanical power transmission systems, including manufacturing equipment, conveyors, pumps, and motor-driven machinery.
