Ruland Aluminium Clamp Style Flexible Coupler 25mm Bore 57.2mm OD 28.7mm Length MOCT57-25-A

Ruland MOCT57-25-A Aluminium Clamp Style Flexible Coupler offers a robust and precise coupling solution for mechanical power transmission in industrial and motion control environments. Featuring a 25mm bore diameter and a 57.2mm outside diameter with a hub length of 28.7mm, this clamp style coupling is designed to provide secure and reliable shaft connection without the use of a keyway bore.

Made from high-grade anodised aluminium, the coupler hubs are lightweight and resistant to corrosion, contributing to long-term durability. The coupling is suitable for applications with maximum speeds up to 4500 rpm, accommodating slight angular (0.5°), parallel (0.25mm), and axial (0.2mm) misalignments, which helps protect connected machinery from undue stress.

The assembly requires two clamp-style hubs paired with a torque disc, providing a three-piece design that facilitates torque transmission while safeguarding components by acting as a torque limiter due to the breakable center disc made of acetal or nylon. The unique design enhances performance in motion control applications involving stepper or servo motors.

Securing the hubs involves set screws, with smaller hubs using a single set screw per shaft and larger hubs featuring two screws set 90° apart for added stability. This coupling complies with REACH and RoHS standards, ensuring environmental and health safety in manufacturing and use.

Originating from the United States, this coupling is ideal for light industrial settings, motion control systems, and applications requiring electrical isolation and speed reliability. Its clamp style is advantageous for maintenance and installation ease, making it a preferred choice among professionals in the field.
