Ruland MOCT57-19-A Oldham Coupling Clamp Style Hub.

Ruland MOCT57-19-A is a clamp Oldham coupling hub with a 19mm bore, 57.2mm OD, and 28.7mm length.

It is a component of a three-piece design consisting of two anodized aluminum 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.

Disks are available in three materials allowing the user to tailor coupling performance to their application.

MOCT57-19-A can accommodate all forms of misalignment and is especially useful in applications with high parallel misalignment (up to 10% of the OD). It operates with low bearing loads protecting sensitive system components such as bearings and has a balanced design for reduced vibration at speeds up to 6,000 RPM.

Hardware is metric and tests beyond DIN 912 12.9 standards for maximum torque capabilities.

MOCT57-19-A is machined from bar stock that is sourced exclusively from North American mills and is RoHS3 and REACH compliant. It is manufactured in our Marlborough, MA factory under strict controls using proprietary processes.
