SHF - Retaining Ring
External Friction Inch- This ring resembles a regular SH ring except that it is designed to function on a shaft without a groove. The design of the ring causes it to exert significant gripping power uniformly on the shaft (except where the gap occurs).
Size Range: .059-.750 Inches.

TX/TY - Retaining Ring
External Toothed Inch- This ring features an outer rim with a series of prongs protruding into the center. The ends create interference with the shaft when the ring is installed and a load introduced to the other side. The difference between these two rings is that the outer rim of the TX is curved while the rim of the TY is flat.
Size Ranges: TX--.094-1.0 Inches; TY--.094-1.0 Inches; DTX—1.5mm-45.0mm.

TI- - Retaining Ring
Internal Toothed Inch- The internal version of the TY featuring a series of prongs protruding into the center. The ends create interference with the housing when the ring is installed and a load introduced to the other side.
Size Ranges: TI--.312-.938 Inches; DTI—8.0mm-50.0mm.
