PRODUCT SPECIFICATIONS

Ruland SCC-24-24-F is a set screw rigid coupling with 1.5000" x 1.5000" bores, 2 5/8" OD, 3 7/8" length, and 3/8" x 3/8" keyways. It has precision honed bores to ensure they are collinear and do not introduce misalignment or vibration into the system making it suitable for high precision servo appliactions as well as shaft to shaft connections. Forged screws test beyond ANSI standards to ensure maximum holding power. Tightly controlled bore tolerance of +.002"/+.0005" is maintained. SCC-24-24-F is made from 1215 lead-free steel with a proprietary black oxide finish that produces a fine glossy finish while increasing holding power and resisting corrosion. It is machined from solid bar stock that is sourced exclusively from North American mills and is RoHS3 and REACH compliant. SCC-24-24-F is manufactured in our Marlborough, MA factory under strict controls using proprietary processes.

Installation Instructions

  1. Align the SCC-24-24-F set screw rigid coupling on the two shafts to be connected. There should be no misalignment.
  2. Tighten the set screws in two stages, starting with the inside set screws. Using a 3/16 in torque wrench, tighten the inside set screws to 145 lb-in which is half the recommended seating torque. Repeat for the outside set screws, again tightening to half of the recommended seating torque.
  3. Tighten the screws to the full recommended seating torque of 290 lb-in following the same pattern, starting with the inside set screws first.
