Notes

  • An open ring that springs into a shaft groove, with two lugs (Ø3.2, Ø1.4 holes) either side of the gap. The ring bore is the groove Ø; its OD is 1.9 × the shaft Ø and the gap is 0.35 × the groove Ø.
  • Groove Ø × width (ring thickness) by shaft: 4 → 3.8 × 0.5 (0.4); 5 → 4.8 × 0.7 (0.6); 6 → 5.7 × 0.8 (0.7); 8 → 7.6 × 0.9 (0.8); 10 → 9.6 × 1.1 (1.0); 12 → 11.5 × 1.1 (1.0); 15 → 14.3 × 1.1 (1.0); 20 → 19.0 × 1.3 (1.2).
  • The groove itself is drawn on shaft-8x100-grooved (Ø7.6 × 0.9).
