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.</p><p> 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.</p>
