Combined Bearings
Lifting and handling in a economical way.


Dimensioning /calculation of the reel load



Q = Load capacity (N)
L = Load distance to suspension point (mm)
P = Suspension point
A = Bearing distance (mm) recommended 500-1000 mm

Formula
F max [N] = (Q * L) / (2 * A)
stat.radial

To avoid wear out in the profile, which is not hardened, the pressure between bearing and profile should be max.
P zul = 860 N/mm² for Nb-profiles (St.0-St.6 + PR0-PR6)
P zul = 750 N/mm² for all profiles except Nb-series.
Here indicated are F max stat radial + axial for each bearing.
