Request a quoteWanHu supplies this yellow cotton buffing wheel family in several diameters and sewn densities. The soft cloth face provides flexible contact and holds polishing compound during use.
Choose the diameter and density for polishing flat, curved or moderately shaped surfaces. Suitable applications depend on the workpiece material, compound and machine speed.

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
