Ruland Clamp Style Aluminium Jaw Coupler 33.3 mm OD 8 mm Bore 44.5 mm Length No Keyway MJC33-8-A

Ruland MJC33-8-A is a clamp style aluminium jaw coupling hub designed for high performance mechanical power transmission. Featuring a 33.3 mm outside diameter, 8 mm finished bore without keyway, and a 44.5 mm length, this coupler provides a balanced and reliable connection between shafts at speeds up to 8000 rpm.

The coupling is constructed from lightweight, corrosion-resistant aluminium suitable for demanding industrial environments including mechanical machinery applications, manufacturing equipment, and power transmission systems. Its clamp style design ensures secure torque transfer while accommodating minor misalignments between connected components.

This product is part of a three-piece jaw coupling assembly requiring two hubs and an elastic polyurethane jaw spider inserted between them, which must be ordered separately. The elastic spider element provides damping characteristics to minimize shock load impacts, reducing wear on motors and sensitive equipment.

The aluminium hubs are electrically isolating and designed to deliver low to medium torsional rigidity with a fail-safe design that allows continued operation even if the spider element fails. Multiple hardness options for the spider are available to optimize coupling performance for different torque and damping requirements.

The coupler meets important manufacturing and environmental standards such as DIN 91 1.9, RoHS, and REACH, reflecting its compliance with international quality and safety norms. It is manufactured in the United States, ensuring strict production quality and consistency.

Constructed from aluminium for durability and corrosion resistance. Clamp style jaw hub suitable for high torque applications. Designed for speeds up to 8000 rpm with balanced performance. Finished bore with no keyway for smooth shaft fit.

Requires two hubs and a jaw spider for full coupling assembly. Elastic polyurethane spider minimizes shock and vibration. Electrically isolating to protect sensitive equipment. Complies with DIN 91 1.9, RoHS, and REACH standards.

Manufactured in the United States ensuring high quality.

This Ruland jaw coupler is ideal for industrial mechanical power transmission, manufacturing machinery, and fluid power applications requiring flexible, durable coupling solutions. For completed assembly, ensure to purchase the matching hubs and jaw spider separately. Explore EnvMart for more mechanical power transmission products and reliable coupling options.
