Ruland CLX-6-6-F One-Piece Clamp Coupling

The CLX-6-6-F from Ruland is a one-piece rigid clamp coupling designed to join two shafts with 3/8" bores, delivering a compact 7/8" outer diameter and a total length of 1-3/8". Constructed in steel with a black oxide finish, it uses four #6-32 socket-head screws with NyPatch anti-vibration coating to promote even seating and reduce galling, tightened to a 28 in-lb seating torque. Bores are specified as 0.3750" x 0.3750" with a finished-bore tolerance of +0.0020" / +0.0005", and the unit weighs approximately 0.172 lb; this clamp coupling is suitable for high-precision shaft-to-shaft connections and servo or motor drives. Made in the USA, the CLX-6-6-F is a clamp-style coupling without a keyway, designed to provide secure, repeatable performance in demanding applications.
