A bigger wheel must run slower. The limit is set by peripheral speed (how fast the rim travels), not by a fixed RPM number — so the safe RPM drops as the diameter grows.
| Wheel diameter | Spec code | Max. safe speed | Peripheral speed at that limit |
|---|---|---|---|
| Ø 100 mm4" | 4 × 50 | ≤ 6,000 RPMMaker rating on small wheels — the arbor and guard set the real ceiling | 31.4 m/s |
| Ø 150 mm6" | 6 × 50 | ≤ 3,000 RPMMost common size — many makers rate it at 2,800 RPM | 23.6 m/s |
| Ø 200 mm8" | 8 × 50 | ≤ 2,200 RPM | 23.0 m/s |
| Ø 250 mm10" | 10 × 50 | ≤ 1,800 RPM | 23.6 m/s |
| Ø 300 mm12" | 12 × 50 | ≤ 1,400 RPM | 22.0 m/s |
Spec code format: diameter (inch) × ply count — 4 × 50, 5 × 50, 6 × 50, 7 × 50, 8 × 50, where 50 ply means 50 cotton layers. Finished thickness is 12 mm across the whole range.
Peripheral speed = π × diameter (m) × RPM ÷ 60
