Installation & Removal Advantages of Spirolox Retaining Rings

Spirolox(R) Retaining Rings are specified to literally retain components within a bore or shaft. What sets them apart from other retaining rings on the market is that they are designed with “No Ears to Interfere(R),” so there is nothing to get in the way of assemblies. But if there are no “ears” or “lugs,” how are Smalley’s rings installed?

Our rings can easily be installed by hand. First separate the coils, then insert one end directly into the groove, and then wind the rest of the ring into place. This process is the same for internal and external applications.

There are also semi-automated and automated processes for installing Spirolox(R) Retaining Rings:

For an internal application, a plunger and tapered housing sleeve are used together; the sleeve acts as a guide while the plunger pushes the ring into place. For an external application, a plunger and tapered plug are used; the plug is centered over the shaft end and the plunger pushes the ring into position over the plug. (In both cases a 6° angle is recommended.)

Removing our retaining rings is just as simple, and no special tools are required. A removal notch in the ring provides a small gap that a flat tool, like a screwdriver, can be inserted under to pry the first layer free. When that is loose, simply grab the ring and unwind it out of the groove.
