Ruland CLX-10-10-F, 5/8" x 5/8" Rigid Coupling, Black Oxide Steel, One-Piece Clamp Style, 1 5/16" OD, 2" Length


Ruland CLX-10-10-F is a one-piece rigid coupling with 5/8" x 5/8" bores, 1 5/16" OD, and 2" length. It has precision honed bores on to ensure bores are collinear and does not introduce misalignment or vibration into the system making it suitable for high precision servo appliactions as well as shaft to shaft connections. Proprietary Nypatch® anti-vibration coating on hardware allows for even seating of the screw, repeated screw installations, prevents galling, and maintains high holding power. It eliminates the need to treat screws upon receipt greatly reducing installation time. Forged screws test beyond ANSI standards to ensure maximum holding power. Tightly controlled bore tolerance of +.002"/+.0005" is maintained. CLX-10-10-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 RoHS2 and REACH compliant. CLX-10-10-F is manufactured in our Marlborough, MA factory under strict controls using proprietary processes.

Installation Instructions

Installation Instructions

  1. Align the coupling on the two shafts to be connected. There should be no misalignment.
  2. Tighten the #10-32 Nypatch® screws in two stages. Starting with the inside screws, tighten to half the recommended seating torque of 76 lb-in. Repeat for the outside screws, again tightening to half of the recommended seating torque.
  3. On two-piece couplings be sure to maintain the gap between the two halves during installation.
  4. Tighten screws to the full recommended seating torque of 76 lb-in following the same pattern, beginning with the inside screws first.
