Short Rigid Couplings

Short rigid couplings can be used in applications where space is limited. The short rigid coupling has a reduced torque capability compared to a standard rigid coupling due to its use of a single socket head cap screw per shaft. However, the compact size of the collar reduces inertia making it ideal for motion control applications. Ruland manufactures short rigid couplings in 1215 lead-free steel with a proprietary black oxide finish, 303 stainless steel, and high-strength 2024 aluminum. Bore sizes range from 1/8" to 2" and 6mm to 25mm.

Features

  • Does not mar the shaft
  • Superior fit, finish and holding power
  • Excellent for high axial loads
  • Transmit torque in confined spaces
  • Step bores available
  • Additional sizes available
  • RoHS3 and REACH Compliant
  • Width tolerance: +.003"/-.010"
  • Temperature Range (Deg. F)
    Steel: -40° to 350°
    Aluminum: -40° to 225°
    Stainless: -40° to 350°
