The Ruland D bore zero backlash jaw coupling hub is a precision-engineered component designed to ensure a positive drive in applications where slippage is not an option. It is part of a three-piece coupling system consisting of two aluminum hubs and an elastomeric insert, known as the spider, which facilitates torque transmission while minimizing backlash. This lightweight, low-inertia coupling can operate at speeds of up to 8,000 RPM, making it suitable for high-speed machinery and motion control systems requiring precise, vibration-free performance.

Hardware is metric and tests beyond DIN 912 12.9 standards for maximum torque capabilities
It is machined from bar stock that is sourced exclusively from North American mills
RoHS3 and REACH compliant
