TOLERANCES

Shaft h8 – k6 (size 15 only h7)
When using k6 shaft – transmittable torque will increase by 20%.
Can also be used with h9 shaft – Transmittable torque will be
reduced by 25%.
Hub H7.

Type of torque

Transmittable torque, T, is for static load.
If the load is alternating or pulsating torque, reduce
the transmittable torque, T, with the following factors:
(factor x T).

Alternating:
0,6 x T for sizes 15 – 30 mm.
0,5 x T for sizes 32 – 100 mm.
Pulsating:
0,7 x T for sizes 15 – 30 mm.
0,6 x T for sizes 32 – 100 mm.

Tightening torque

By increasing the tightening torque of the screw sizes
according to the table, the transmittable torque can
be increased by 25%.
Note: Only to be used when operating temperature
≤ mounting temperature.
