Ruland CPRD48-20-A, Controlflex Coupling Hub, Aluminum, Clamp Style, 2.953" OD, 2.874" Length

PRODUCT SPECIFICATIONS

Ruland CPRD48-20-A is a Controlflex coupling hub with a 1.2500" bore, 2.953" OD, and 2.874" length. It is a component in a four-piece design consisting of two aluminum hubs mounted by pins to two acetal inserts creating a lightweight low inertia coupling capable of speeds up to 7,500 RPM. This four-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 have a balanced design for reduced vibrations at high speeds, can accommodate all forms of misalignment, and are an excellent fit for encoders, tachometers, and light duty stepper servo positioning applications. CPRD48-20-A is RoHS3 and REACH compliant.

Product Notes

Nota 1

Stainless steel hubs are available upon request.

Nota 2

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

Nota 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.

Installation Instructions

  1. Align the bores of the CPRD48-20-A controlflex coupling hub on the shafts that are to be joined with the drive pins facing each other and determine if the misalignment parameters are within the limits of the coupling. (Angular Misialignment: 1.0°, Parallel Misalignment: 2.0 mm, Axial Motion: 1.5 mm)
  2. Rotate the hubs on the shaft so the drive pins are 90° from each other.
  3. Place the first hub at the end of the shaft. Tighten the clamp screw to 24.0 Nm using a 6.0 mm hex torque wrench.
  4. Place an insert(s) with the standoffs facing the hub over the pins of the hub that was just installed.
  5. Align the drive pins on the second hub to match the holes in the insert(s).
  6. Verify that the space between hubs is 1.456 in, 37.0 mm.
  7. Tighten the clamp screw on the second hub to the recommended seating torque of 24.0 Nm using a 6.0 mm hex torque wrench.
