Self-Locking Rings

Self-locking retaining rings can be installed on a shaft or in a housing/bore without using a groove.  They save machining time and overall costs since a groove is not needed for installation.  They also come in small sizes (some fitting shafts as small as .058" in diameter) and can be used effectively and economically on small applications with very low thrust loadings.  Most self-locking retaining rings can not be easily removed once installed.

SHF - External Shaft Friction Ring
The SHF 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.)

SHF Size Range: .058 - .755 inches

RG - External Radial Grip Ring
The RG makes indentations on either side of the groove once installed which significantly increases its holding power.  It can also be installed directly against the face of the retained part, virtually eliminating end play.  Automated installation using a Rock Kick Jr. pneumatic installation tool.  (Note; this product works only on "soft" shafts.)

RG Size Range: .092 - .379 inches

TX - Toothed External "Push on" Ring

(Curved Rim)
This ring features an outer rim with a series of prongs protruding into the centre.  The ends create interference with the shafts when the ring is installed and a load introduced to the other side.  The outer rim of the TX is curved.  The curved rim of the TX affords greater thrust load capacity than the TY and is easier to orient for assembly.

TX Size Range: .091 - 1.005 inches

TY - Toothed External "Push on" Ring

(Flat Rim)
This ring features an outer rim with a series of prongs protruding into the centre.  The ends create interference with the shafts when the ring is installed and a load introduced to the other side.  The outer rim of the TY is flat.

TY Size Range: .093 - 1.002 inches

TI - Toothed Internal "Push on" Ring
The internal version of the TY featuring a series of prongs protruding outward.  The ends create interference with the housing when the ring is installed and a load introduced to the other side.

TI Size Range: .311 - 2.002 inches
