The Ruland Clamp single disc coupling with keyways is a high-precision mechanical coupling designed for zero-backlash torque transmission, ensuring accuracy and reliability in motion control applications. Its balanced design minimizes vibration at high speeds, improving stability and efficiency. The coupling consists of two anodized aluminum hubs with integrated keyways for secure shaft attachment, along with thin stainless steel disc springs that allow for angular misalignment and axial movement while maintaining structural rigidity. However, it does not support parallel misalignment, requiring precise shaft alignment for optimal operation.

Lightweight and has low inertia making it well suited for applications with speeds up to 10,000 RPM
Hardware is metric and tests beyond DIN 912 12.9 standards for maximum torque capabilities
It is machined from solid bar stock that is sourced exclusively from North American mills and RoHS3 and REACH compliant
