Spiral retaining rings offer many advantages over stamped retaining rings:

• No Gap - 360° retaining surface provides dimensional stability
• No protruding ears to interfere with mating components
• Economically produced because the coiling process produces no scrap
• Circular Grain, coiled not stamped
• Stock sizes in Carbon and Stainless Steel
• Custom rings available in 0.200" to 90" diameters
• Exotic alloys available
• Easy installation and removal

Ring Application Examples

Air Hose Nozzle

Single turn retaining ring fits tightly onto the groove of plastic air vent housing. Ring ends are dimensioned close together providing a complete 360 ring support.

Right-Angle Gear

The snap rings secure bearings by providing a removable shoulder in the bore. This simplifies the design and it replaces costly flanged end-plates.

Roller Bearing

Designed especially for flexing in a shallow groove, this retaining ring holds the needle bearing cage assembly in the bearing housing. A previously unreliable operation of roll forming the housing was eliminated when this ring was incorporated into the design.

Pulley

Retaining rings provide 360 degree side walls on both sides of the timing belt pulley. Design eliminates costly pressed-on stamped side walls. For easy belt replacement one ring can easily be removed.

ID/OD Lock

Spiral Retaining Rings can operate in an internal and an external groove at the same time! Spiral retaining rings have many great benefits for the ID/OD Lock, some of which include concealed fastening, no required assembly tooling, and a 360-degree rotational capacity. With a Spiral Retaining Ring, the application is tamper-proof and aesthetically pleasing. In this featured application, the ring is initially installed in the housing groove. When the mating component in the assembly is added, the ring compresses into the groove. The groove is deep enough for the rings radial wall to fit into as the component slides into position. Finally, when the grooves meet, the ring snaps into the shaft groove (groove depth equals 1/2 the rings radial wall) while still in the housing groove.

Rotary Union

The union cross section of the spiral retaining ring allows the ring to be installed in the assembly without interfering with mating components.
