A new series of 11 grooveless external retaining rings from Sterling Instrument (An ISO 9001+AS9100 Registered Manufacturer) are designed for use on ungrooved shafts, bosses, tubes and studs. Identified as the S73NW2 [Inch] [Metric] Series, they exert a frictional hold against axial displacement from either direction.

They feature greater gripping strength, resistance to relative rotation between the ring and the retained parts, wider application acceptance, adjustable in either axial direction, and reusable while not marring the shaft surface during assembly or disassembly. They are made of PH 15-7 Mo Stainless Steel and are designed for shaft diameters which range from 3/32" to 3/4" diameter. The retaining ring clearance ranges from
.26" to 1.32".
