Ruland zero-backlash jaw couplings have a balanced design, accommodate all forms of misalignment and have high dampening capabilities, making them an ideal fit for precision conveyors with frequent starts and stops. These conveyor applications are often found on equipment used in semiconductor, solar, optical inspection and medical automation. Jaw couplings offer system designers a wide range of sizes and performance characteristics to fit their application requirements.
Zero-backlash jaw couplings from Ruland are made from two polished aluminium hubs and a spider type insert. The curved jaw profile of the hubs press fits to the spider, ensuring zero-backlash operation. Hubs are available in clamp or set screw style with inch, metric, keyed, and keyless bores. Spiders are available in three durometers: 98 shore A for high stiffness, 92 shore A for a balance of stiffness and compliance and 85 shore A for the highest amount of dampening. Conveyor designers can mix and match hubs and spiders to create a coupling that best fits the need of their application.
