Ruland SPX-20-20-F is a two-piece rigid, clamp-style shaft coupling designed for shaft-to-shaft connections, with equal 1-1/4" bores. It has an outer diameter of 2-1/16" and an overall length of 3-1/4", with bore tolerances of +0.0020"/+0.0005". The component is machined from 1215 lead-free steel, finished in black oxide, and is RoHS3 and REACH compliant, manufactured in Marlborough, MA. NyPatch anti-vibration coating on the hardware improves seating and reduces galling, and the screws are forged and tested beyond ANSI standards to maintain high holding power.
