Product Description
Ruland MOCT57-24-A Clamp Style Oldham Coupler is engineered for reliable mechanical power transmission, featuring a 24mm bore, 57.2mm outside diameter, and a 28.7mm hub length. The coupling is finished with no keyway bore and constructed from black anodised aluminium hubs, offering excellent durability and corrosion resistance.
This three-piece clamp style coupling includes two hubs and a replaceable centre torque disc made from acetal or nylon, which provides mechanical overload protection by breaking cleanly during torque spikes to safeguard connected machinery.
The design accommodates small angular (0.5°), parallel (0.25mm), and axial (0.2mm) misalignments, making it ideal for light industrial, motion control, servo, and stepper motor applications requiring precise shaft coupling at speeds up to 4500 rpm.
Hubs are secured to shafts using one or two set screws depending on hub size to ensure a secure fit. Manufactured in the United States, this coupling complies with RoHS and REACH regulations, ensuring environmental and safety standards.
The coupling hubs are black anodised aluminium for strength and corrosion resistance. The centre torque disc is replaceable and made of acetal or nylon. Supports small misalignments critical for motion control applications.
Maximum operational speed up to 4500 rpm. Clamp style design allows for quick installation and replacement. Provides torque overload protection by cleanly breaking the centre disc. Set consists of two hubs and one torque disc for full assembly.
This coupling is suitable for use in multiple industrial sectors including mechanical, manufacturing, laboratory, and motion control environments where precise, reliable shaft coupling is required. For related products, explore the Mechanical Power Transmission Couplers category at EnvMart.
