Combined Bearings
Lifting and handling in a economical way.


Jumbo-profiles



Product Information

All profiles are made from high-quality steel UNI FE 510.C.
To our Combined Bearing system, we produce all profiles in fixed lengths, according to customers order.
Low cost version with milled profile only on one side on request.
Maximum production length 12 m.
U-profiles and special designs on request.

Dimentionsing

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

Formula

Fmax [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.
Pzul = 860 N/mm² for Nb-profiles (St.0-St.6 + PR0-PR6)
Pzul = 750 N/mm² for all profiles except Nb-series.
Here indicated are F maxstat radial + axial for each bearing.
