Notes
- A ring with one radial tapped hole at mid-width: bore Ø × OD × width and screw: 3 × 8 × 5 M3; 4 × 9 × 5 M3; 5 × 10 × 6 M3; 6 × 12 × 7 M3; 8 × 16 × 8 M4; 10 × 20 × 10 M4; 12 × 22 × 10 M5.
- The bore is the shaft Ø exactly; the screw hole is drawn at the tap drill: Ø2.5 (M3), Ø3.3 (M4), Ø4.2 (M5).
- A collar each side of a bearing locates a shaft along its axis; the set screw seats on the shaft's D-flat.
