How to install a Spirolox Retaining Ring: For higher speed assembly operations retaining ring installation is accomplished with a plunger and a tapered plug. The plug, angled at approximately 6 degrees, is centered over the shaft end. A loose fitting plunger pushes the snap ring into position over the tapered plug. An arbor press or air cylinder is commonly used to automate this assembly operation. Tooling for retaining ring installation should have hardened working surfaces to minimize wear.
