Electrically Isolating Disc Coupling
Ruland electrically isolating double disc couplings are comprised of two anodized aluminum hubs, two sets of stainless steel disc springs, and an acetal center spacer. This design allows the sets of disc springs to bend independent of each other to accommodate all forms of misalignment, including parallel. Ruland disc couplings are zero-backlash and have a balanced design for reduced vibration at speeds up to 10,000 RPM. They are a simple assembly with few moving parts, reducing the risk of backlash and premature failure. Clamp and set screw hubs are available in bore sizes from 1/8” to 1-1/4” and 3mm to 30mm.

Zero backlash
RoHS3 and REACH Compliant
Maximum speed: 10,000 RPM
Temperature Range: -10°F to 150°F
How to Specify Part numbers are in the following format with numbers representing sixteenths of an inch or millimeters:
