Module A — Grooved Axial Retaining Ring. This calculator uses generalised mechanical design relationships and engineering curve fits for first-pass sizing only. Results must be verified against the selected ring manufacturer’s published data, actual material condition, dimensional tolerances, and physical testing before use in any production design. Free to use — no warranty expressed or implied.
