Ruland CPRS12-6-A, Controlflex Coupling Hub, Aluminum, Clamp Style, 0.748" OD, 0.630" Length

PRODUCT SPECIFICATIONS

Ruland CPRS12-6-A is a Controlflex coupling hub with a 0.375" bore, 0.748" OD, and 0.220" length. It is a component in a three-piece design consisting of two aluminum hubs mounted by pins to one acetal insert called frogs creating a lightweight low inertia coupling capable of speeds up to 25,000 RPM. This three-piece design allows for a highly customizable coupling that easily combines clamp hubs with inch, metric, keyed, and keyless bores. Hardware is metric and tests beyond DIN 912 12.9 standards for maximum torque capabilities. Controlflex couplings are designed for flexibility and an excellent fit for encoders, tachometers, and light duty stepper servo positioning applications. CPRS12-6-A is RoHS2 and REACH compliant.

Product Notes

Note 1

Stainless steel hubs are available upon request.

Note 2

Performance ratings are for guidance only. The user must determine suitability for a particular application.

Note 3

Torque ratings for the couplings are based on the physical limitations/failure point of the inserts. Under normal/typical conditions the hubs are capable of holding up to the rated torque of the inserts. In some cases, especially when the smallest standard bores are used or where shafts are undersized, slippage on the shaft is possible below the rated torque. Keyways are available to provide additional torque capacity in the shaft/hub connection when required. Please consult technical support for more assistance.
