Product Description
Ruland MOCT57-16-A flexible clamp style coupler features a 16mm bore diameter, 57.2mm outside diameter, and 28.7mm hub length, making it optimized for precision mechanical power transmission. This clamp style Oldham coupling accommodates small axial and angular misalignments typically encountered in light industrial and motion control applications such as servo or stepper motor drives.
The hubs are formed from black anodised aluminium, providing a combination of strength, corrosion resistance, and lightweight design. The centre torque disc, made of acetal or nylon, acts as a torque limiter to protect the drivetrain by breaking cleanly under torque overload conditions. This design ensures extended equipment life and reliable performance.
The coupling supports a maximum rotational speed of 4500 rpm and can handle misalignments including angular up to 0.5°, parallel up to 0.25mm, and axial movement up to 0.2mm. Its finished bore without keyway allows a snug fit on shafts and ease of installation.
The clamp style securing mechanism varies by hub size; smaller hubs use one set screw while larger ones employ two set screws positioned 90 degrees apart for secure attachment. Note that the product is not supplied fully assembled; a complete assembly requires two hubs and one torque disc.
This flexible coupling is well suited for mechanical power transmission tasks in industrial manufacturing, automation, laboratory instruments, HVAC systems, and other applications requiring reliable torsional connectivity with the ability to accommodate slight shaft misalignments.
Clamp style Oldham coupling for axial and angular misalignment accommodation. Black anodised aluminium hubs offer corrosion resistance and strength. Replaceable acetal or nylon torque disc provides overload protection. Maximum speed rating of 4500 rpm.
Finished bore with no keyway for precise installation. Securing screws vary by hub size for reliable shaft fastening. Two hubs and one torque disc required per assembly. Ideal for motion control, light industrial, and automation use cases.
