Ruland Aluminium Clamp Style Flexible Coupler, 33.3 mm OD, 8 mm Bore, 15 mm Length MOCT33-8-A

Ruland MOCT33-8-A Aluminium Clamp Style Flexible Coupler features a 33.3 mm outside diameter, 8 mm bore diameter, and 15 mm hub length. It is engineered to provide reliable mechanical power transmission by coupling shafts with allowance for minor misalignments. Constructed from black anodised aluminium hubs linked by a centre torque disc made from acetal or nylon, this design offers durability, light weight, and vibration damping.

This coupling style incorporates clamp hubs secured by set screws, offering a firm fit on shafts with appropriate torque transmission and protection from overload by means of replaceable center discs that act as torque limiters. The three-piece design requires two hubs and one torque disc per assembly.

The MOCT33-8-A coupler supports maximum speeds up to 4500 rpm and permits angular misalignment up to 0.5°, parallel misalignment up to 0.2 mm, and axial misalignment up to 0.15 mm, making it suitable for precise motion control, including applications with stepper or servo motors. The bore is finished without a keyway, enhancing flexible shaft integration options.

Manufactured in the United States, this coupling complies with RoHS and REACH environmental standards. Clamp style hubs are black anodised aluminium, with center discs made from acetal or nylon providing both durability and torque overload protection by breaking cleanly when necessary.

This product is ideal for light industrial, laboratory, manufacturing, and HVAC applications requiring high reliability and accurate shaft alignment. Typical use cases include machinery coupling in automated production lines and precision motion control assemblies.

Constructed from high-quality black anodised aluminium for durability and corrosion resistance. Designed to accommodate small axial, angular, and parallel misalignments to protect machinery. Clamp style hubs provide secure shaft coupling with multiple set screw configurations.

Maximum operating speed rated at 4500 RPM for efficient motion control. Complies with RoHS and REACH standards ensuring environmental safety. Ideal for light industrial and motion control applications including stepper and servo motor systems.

Bore is finished with no keyway bore for flexible shaft compatibility. Secure coupling achieved with two hubs and one replaceable torque disc per assembly. Manufactured in the United States ensuring ISO quality standards.

Set contains 1 Pc Clamp Style Oldham Coupler Hub with no keyway bore and 15 mm hub length. Explore more products in Flexible Couplers at EnvMart for advanced mechanical and power transmission solutions.
