Product Description
Ruland MOCT25-6-A clamp style Oldham coupler is a precision mechanical power transmission component designed for coupling shafts with 25.4 mm outside diameter and 6 mm bore diameter, featuring an 11.9 mm hub length. Manufactured from high-quality aluminium, this coupling provides excellent lightweight strength and corrosion resistance.
The clamp style design enables secure attachment to shafts, allowing for ease of installation and removal without requiring a keyway, as the bore is finished without one. It accommodates slight misalignments including angular, parallel, and axial deviations, which helps protect connected equipment from damage due to shaft misalignment.
The coupling is rated for maximum operating speeds up to 4500 rpm, making it suitable for a variety of light industrial and motion control applications such as servo and stepper motor driven systems. The coupling's unique design includes a three-piece structure consisting of two hubs and a torque disc, which is replaceable and acts as a torque limiter to protect machinery from overload.
The hubs are secured to shafts using set screws (secured on anodized aluminium hubs at 13 mm and 19 mm sizes with one set screw each, larger hubs have two screws at 90° apart), ensuring locking reliability during operation. Note that the product is supplied as individual parts; assembly requires two hubs and one torque disc per complete coupling.
This coupling complies with REACH and RoHS standards and is manufactured in the United States, maintaining stringent quality and environmental guidelines. Constructed from aluminium for corrosion resistance and light weight.
Clamp style design for easy shaft coupling and removal. Accommodates angular, parallel, and axial misalignments. Three-piece design enables torque overload protection. Maximum operating speed of 4500 rpm. Suitable for mechanical power transmission and motion control applications.
