Product Bulletin 41

The size of the bearing and the axle shaft section or diameter, determines the overall load carrying capacity of the axle and hub assembly. Different bearing types are capable of different load capacities (see the chart below). The bearing type can be identified by the part number stamped on the bearing cone.

Bearing Type & Load Capacity
A Type Bearing = 750 Kg to 1000 Kg load capacity
B Type Bearing = 1400 Kg load capacity
C Type Bearing = 1600 Kg load capacity
D Type Bearing = 2200 Kg to 2500 Kg load capacity
E Type Bearing = 3500 Kg load capacity
F Type Bearing = 4000 Kg to 5000 Kg load capacity
Important Note: The combination of (A) Bearing Type and (B) Axle Shaft Section Size / Diameter will determine the Maximum Load in Kilograms, per Axle Shaft or Pair of Stub Axles.
