• Precision honed bores for superior fit and torque transmission. Does not mar the shaft. Keyways are used for additional torque transmission capabilities and to prevent slippage on the shaft.
• Proprietary Nypatch anti-vibration hardware prevents galling, maintains high holding power, and allows for multiple screw insertions. Nypatch significantly reduces installation time as no additional screw treatment is needed prior to use.
• Made from 1215 lead-free steel with proprietary black oxide finish for increased holding power and corrosion resistance.
• Hardware tests beyond ANSI standards for maximum torque capabilities
• Ruland rigid couplings are carefully made from select North American bar stock in our Marlborough, Massachusetts factory and are RoHS3 and REACH compliant
