Set Screw Rigid Couplings
Set screw rigid couplings from Ruland have precision honed bores to ensure they are collinear. This is important when the rigid coupling is used in a precision servo system or on a mixer as honing allows for greater surface contact with the shaft and higher torque transmission capabilities. Ruland manufactures set screw rigid couplings in 1215 lead-free steel and 303 stainless steel.
Features Precision honed bore on straight bore couplings
Clamp style couplings available
Additional sizes available
RoHS3 and REACH Compliant
Maximum speed: 4,000 RPM
Temperature Range (Deg. F)Steel:
