Ruland MOCT33-9-A 2024/7075 Aluminum Oldham Coupling Hub - Clamp Style, 9mm Bore, 33.3mm OD - Ideal for CNC Machines, 3D Printers & Motion Control Systems

Ruland Oldham couplings are highly customizable, have a balanced design, and have low inertia. While they can accommodate all forms of misalignment, they are especially useful in applications with parallel misalignment.This Oldham coupling hub is manufactured from 2024 aluminum for lightweight and low inertia. To make a complete coupling you must select two hubs and a disk insert.Oldham couplings are highly customizable allowing the user to easily combine clamp or set screw hubs with inch, metric, keyed, and keyless bores. The performance of the coupling is determined by the disk which is available in acetal for zero-backlash and high torque, nylon for dampening of impulse loads, and PEEK for high temperature. Ruland manufactures Oldham couplings with a proprietary hub machining process that leaves a smoother surface for interaction between the hub and disk resulting in significantly longer life. Oldham couplings have very low bearing loads protecting sensitive equipment and components from premature failure. Ruland Oldham couplings are carefully made from select bar stock sourced exclusively from North American mills and are machined to a fine burr-free finish. Hardware tests beyond DIN 912 12.9 standards for maximum torqueing capabilities. Ruland, founded in 1937, manufactures all products in our Marlborough, MA USA factory under strict controls using proprietary processes. Oldham couplings are RoHS2 and REACH compliant.

Ruland oldham couplings have a zero-backlash balanced design for reduced vibration at speeds up to 4,500 RPM.

Can accommodate high amounts of parallel misalignment (up to 10% of the hub OD). Acts as a mechanical fuse stopping power transmission during a torque overload.

User can combine clamp or set screw hub with inch, metric, keyed, or keyless bore for a high level of customization. Proprietary hub machining process for smooth interaction between the hub and disk allowing for significantly longer life

Made from high strength 2024 aluminum with a black anodized finish for light weight and low inertia.

Hardware exceeds DIN 912 12.9 standards for maximum torque capabilities. Ruland oldham couplings are carefully made from select North American bar stock in our Marlborough, Massachusetts factory and are RoHS3 and REACH compliant.
