INTERNAL & EXTERNAL AXIAL

Ends of the internal axial ring are pinched together enough to pass down into a bored groove using retaining ring pliers then released to spring outwards and lock into the groove. With external axial rings, ends are expanded to pass over a shaft then released to spring back into the grooved are. Both of these have become the widest used, most reliable and least expensive retaining devices available.

EXTERNAL RADIAL

For use where it is impractical to apply an external ring, where speed of assembly and low unit cost are essential and where large bearing area but low stress situations are involved. They may be installed and removed with a screwdriver or special applicator tool.

END PLAY TAKE-UP

These clips are bowed for resilient take-up of end play. Rigid take-up may be achieved by using a beveled ring. They are installed by pushing into an external groove on the side of the shaft using the special pliers available.

EXTERNAL & INTERNAL WIRE RINGS (SNAP RINGS)

The simplest form of retainer, used where little shoulder and low thrust-load capacity is required or where clearance must be kept to a minimum. They offer large shoulder or bearing surfaces and are less costly than stamped rings. Can be easily installed and removed by hand.

PUSH-ON FASTENERS

Used on low carbon steel applications to provide permanent shoulders in housings and on shafts. The fastener is pushed axially onto the shaft or into the bore by hand or with an applicator. No groove is needed, the prongs embed into the material when a load from the opposite direction is applied.
