Home >> Retaining Rings >> Self Locking
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.
Technical Resources
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.)
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.)
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.
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.
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.
Size Range: .331 – 2.002 inches
Self-locking and push-on tapered section retaining rings combine small size, easy installation and security in one solution. They are suitable for devices with shaft or housing diameters of one inch or less that require very low thrust loads. Rotor Clip’s smallest self-locking retaining rings can fit some shafts as small as 0.058 inches (1.5 millimeters) in diameter.
Self-locking retaining rings are offered in several configurations to position prongs or indentations on the shaft or bore to maximize the uniformity and gripping power to handle the load. Most self-locking retaining rings cannot be removed once installed, giving you peace of mind along with a secure assembly.
Self-Locking and Push-On Internal/External Inch
Choose from an assortment of prongs or indentations designed to maximize uniformity and gripping power for various load requirements, including a push-on version with a curved outer rim for easy installation and an indented version that can be installed directly against the face of the end part to greatly reduce end play.
SHF SERIES
External Shaft Friction Ring
The design of the ring causes it to exert significant gripping power uniformly on the shaft (except where the gap occurs) without a groove.
RG SERIES
External Toothed Push-On Ring
This radially installed ring makes its own groove on a soft shaft, increasing its holding power significantly. Install directly against the face of the retained part, virtually eliminating end-play.
TX SERIES
External Radial Grip Ring
Similar to the TY Toothed External Push On Ring, the outer rim of the TX is curved, affording greater thrust load capacity and easier assembly orientation.
TY SERIES
External Toothed Push-On Flat Ring
This ring features a flat 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.
TI SERIES
Internal Toothed Push-On Ring
This ring features 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.
Self-Locking and Push-On Internal/External Metric
Choose from three different DIN metric configurations designed to maximize uniformity and gripping power for various load requirements.
DSF SERIES
External DIN Self- Locking Friction Ring
The design of the ring causes it to exert significant gripping power uniformly on the shaft (except where the gap occurs).
DTX SERIES
External DIN Toothed Push-On Ring
This ring features 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.
DTI SERIES
Internal DIN Toothed Push-On Ring
This ring features 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.
