The Ruland Zero backlash jaw coupling hub is a key component in a three-piece design that ensures precise torque transmission without any lost motion. It consists of two aluminum hubs and an elastomeric insert, known as the spider, which absorbs vibrations while maintaining flexibility. This lightweight, low-inertia coupling is capable of operating at speeds up to 8,000 RPM, making it ideal for high-speed applications requiring smooth and reliable performance. Its zero-backlash feature ensures accurate motion control, making it a preferred choice in automation, robotics, and precision machinery.

Jaw couplings have a balanced design for reduced vibration at high speeds
Hardware is metric and tests beyond DIN 912 12.9 standards for maximum torque capabilities
RoHS3 and REACH compliant
