Клас на точност
Shafts are produced by grinding in tolerance class h with surface roughness Ra 0,25.
Lengths tolerances are acc. to DIN and ISO norm.
Length tolerance of the shafts
The length tolerance depends on shaft length and corresponds to the norm DIN ISO 13012
| Shaft length L [mm] | Length tolerance [mm] |
|---|---|
| L ≤ 400 | ± 0,5 |
| 400 < L ≤ 1000 | ± 0,8 |
| 1000 < L ≤ 2000 | ± 1,2 |
| 2000 < L ≤ 4000 | ± 2,0 |
| 4000 < L ≤ 6000 | ± 3,0 |
Diamenter tolerance of the shafts
| Shaft type | Diameter tolerance |
|---|---|
| W | h6 |
| WV | h7 |
| WRA | h6 |
| WRB | h6 |
| WH | h6 |
Straightness tolerance of the shafts
| Shaft diameter d [mm] | Straightness on 1000 mm [mm] |
|---|---|
| d ≤ 4 | 0,3 |
| 5 < d ≤ 8 | 0,2 |
| 10 ≤ d | 0,1 |
