Ruland OD16/25-AT Oldham Coupling Disk

Ruland OD16/25-AT is an oldham coupling disk designed to fit hubs with an OD of 1.000″ 25.4mm). It is a component of a three-piece design consisting of two anodized aluminum or stainless steel hubs press fit onto a center disk.

This three-piece design allows for a highly customizable coupling that easily combines clamp or set screw hubs with inch, metric, keyed, and keyless bores.

OD16/25-AT is made from acetal for zero-backlash and high torsional stiffness. Oldham couplings can accommodate all forms of misalignment and are especially useful in applications with high parallel misalignment (up to 10% of the coupling OD).

They operate with low bearing loads protecting sensitive system components such as bearings and have a balanced design for reduced vibration at speeds up to 6,000 RPM. OD16/25-AT is RoHS3 and REACH compliant.

Carefully made by Ruland in Marlborough, MA, Oldham couplings are comprised of two hubs pressed fit with either an acetal or nylon disk. Oldham couplings disengage if the disc breaks, acting as a mechanical fuse. Well-suited for handling large amounts of parallel misalignment. Acetal Oldham coupling inserts are zero-backlash and electrically isolating. Maximum is 4,500 RPM. RoHS and Reach compliant. Also called a Oldham coupling insert, disk, or disc.
