Ruland 25.4 mm OD 8 mm Bore Clamp Style Aluminium Coupler MOCT25-8-A

Ruland MOCT25-8-A clamp style Flexible Coupler is engineered for reliable shaft connections with precise alignment control, featuring a 25.4 mm outside diameter and an 8 mm bore finished with no keyway. The aluminium clamp style hubs provide robust performance and resistance against wear, while the replaceable centre torque disc improves safety by breaking cleanly under overload torque, acting as a protector for connected machinery.

This coupler supports rotational speeds up to 4500 rpm and can handle slight misalignments of shafts including angular (0.5°), parallel (0.2 mm), and axial (0.1 mm) deviations, making it suitable for light industrial and motion control applications such as those involving stepper and servo motors. The clamp hubs are secured onto shafts with set screws positioned according to hub size, ensuring firm attachment and ease of assembly.

Ruland’s design follows strict compliance with REACH and RoHS standards for environmental and safety considerations. Its compact hub length of 11.9 mm allows use in space-constrained environments while maintaining strength and durability. Manufactured in the United States, this coupling meets rigorous quality and material standards required in modern mechanical power transmission systems.

The clamp style provides ease of installation and axial movement accommodation. Aluminium construction reduces weight while maintaining strength. The centre torque disc is replaceable, providing cost-effective maintenance.

Designed for use in precision motion control and light industrial machinery. Supports shafts requiring electrical isolation and torque overload protection.

Reliable and precise, the Ruland MOCT25-8-A coupling is essential for ensuring smooth torque transmission and shaft alignment in varied industrial, manufacturing, and automation settings. For technical reliability and compliance, consider this flexible clamp style coupler in your mechanical power transmission applications.
