Product Description
Ruland MOCT41-12-A Aluminium Clamp Style Oldham Coupler is engineered for flexible shaft coupling applications in light industrial and motion control systems. Featuring a 41.3 mm outside diameter, 12 mm bore finished with no keyway, and an 18 mm length hub, this coupling enables precise connection of shafts while accommodating small axial, angular, and parallel misalignments.
The three-piece clamp style design consists of two black anodised aluminium hubs and a replaceable centre torque disc manufactured from acetal or nylon. This unique assembly allows the torque disc to act as a clean-breaking torque limiter protecting machinery from overloads. The hubs secure shafts via set screws; smaller hubs use one set screw per end, while the 41 mm hubs have two set screws set 90 degrees apart for enhanced grip.
This coupling supports a maximum operating speed of 4500 rpm, making it suitable for high-speed servo and stepper motor drives. The angular misalignment tolerance of up to 0.5 degrees, parallel misalignment of 0.25 mm, and axial misalignment of 0.15 mm provide flexibility in shaft alignment.
Compliant with RoHS and REACH environmental standards, this coupling balances performance with regulatory requirements. Manufactured in the United States, it meets rigorous quality controls for reliable operation in industrial, laboratory, manufacturing, and motion control applications.
Constructed from black anodised aluminium for corrosion resistance. Clamp style hubs secured by set screws for firm shaft connection. Torque disc provides overload protection by breaking cleanly. Accommodates small shaft misalignments for flexible coupling.
High-speed capacity up to 4500 rpm. RoHS and REACH compliant for environmental safety. Requires two hubs and one torque disc for complete assembly.
This coupling is ideal for applications requiring precise motion control and protection against torque overloads, commonly found in industrial automation, manufacturing machinery, and laboratory equipment.
