Medium Heavy Duty

For maximum ease of assembly with maximum thrust capacity. This series of spiral retaining rings was originally designed to fit NAS 50-51 Grooves. RRT (internal) and RST (external) thrust capacity is just below that of the Heavy Duty rings. Sizes range to fit 1/2” to 10” shaft and bore diameters (Sizes above 6” are 3 turn to facilitate assembly and removal).

RRT – Internal

The RRT Series thrust capacity is just below that of the Heavy Duty rings. Retaining ring sizes range to fit 1/2” to 10” shaft and bore diameters (Sizes above 6” are 3 turn to facilitate assembly and removal).

Size Range: .500 – 10.0 inches

RST – External
