ID/OD Retaining Ring Lock

Operate in an Internal and External Groove at the Same Time

Spirolox Retaining Rings, available only from Smalley, can operate in an internal and an external groove at the same time! Spiral type retaining rings have many great benefits for the ID/OD Lock, some of which include concealed fastening, no required assembly tooling and a 360° rotational capacity.

With a Spirolox Retaining Ring, the application is tamper-proof and aesthetically pleasing.

In this featured application, the retaining ring is initially installed in the housing groove. When the mating component in the assembly is added, the retaining ring compresses into the groove. The groove is deep enough for the snap rings radial wall to fit into as the component slides into position. Finally, when the grooves meet, the retaining ring snaps into the shaft groove (groove depth equals 1/2 the retaining rings radial wall) while still in the housing groove.

In the pneumatic fitting application, depicted to the right, a 2-Turn retaining ring without removal notches or an offset, creates an ID/OD lock, permitting the 360° rotation of the nut.
