About
Ruland double disc couplings are comprised of two anodized aluminum hubs, two sets of stainless steel disc springs, and a center spacer. This design allows the sets of disc springs to bend independent of each other to accommodate all forms of misalignment, including parallel. Center spacers are available in anodized aluminum or acetal for electrical isolation. 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 32mm.
Ruland single disc couplings are comprised of two anodized aluminum hubs and one set of stainless steel disc springs. This design allows them to be used in confined spaces where other styles of coupling may not be able to fit. The single set of disc springs does not allow for any parallel misalignment. 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 32mm.

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.
Why Ruland?
- Available in single disc style for a compact design or double disc style for higher misalignment capabilities.
- Anodized aluminum hubs for low inertia.
- Balanced design for reduced vibration and support of higher RPM.
- Screws are used to mount the disc springs, as opposed to rivets, to maintain consistent zero-backlash performance.
- Special designs available for customized torque and misalignment capabilities.
- Inch, metric, and inch to metric bores with or without keyways available from stock.
- Thin stainless steel disc springs provide for long life and accommodate large amounts of misalignment.
- Center spacers on double disc couplings are available in anodized aluminum for increased torque capacity or insulating acetal for electrical isolation.
- All Ruland disc couplings are RoHS3 and REACH compliant.
