Bearing Selection

The selection of a slewing bearing is dictated by the load condition.
These must be compared to the load curves for raceway load capacity and the bolts capacity.

Blue curvesymbolizes the maximum capacity of the bearing.
Red curveindicates the bolting limit capacity (grade 10.9 or 12.9)

To get the effective loads, the nominal loads must be multiplied by the load factor.
The load point revised by load factors must never exceed permissible zone.

Please consider the following general requirements.
