In order to select the best bearing for a particular application, all operational loads should be taken into account. In addition to the weight of the components, the forces created when power is transmitted, such as those listed below, should also be considered:

  • the magnetic pull resulting from asymmetrical air gaps
  • dynamic forces due to misalignment
  • out of balance forces
  • forces due to pitch errors in gears
  • thrust loads

Loads can be radial, axial or a combination of the two. In cases where there are heavy loads,  roller bearings are typically used. Ball bearings are generally used for lighter loads. Certain bearings, such as N and NU type cylindrical roller bearings, accommodate radial loads only while other bearings, such as angular contact ball bearings, are better suited for combined loads.

Generally, Electrically Insulated Bearing (ceramic-coated) exhibit significantly higher resistance to electrical current than standard bearings.

Advantages of Electrically Insulated Bearing :

> Higher operational reliability through optimum protection against current passages

> More economical than insulation on housings or shafts

> Interchangeable: Same dimensions and technical properties as conventional bearings

> Coating resistant to mechanical damage if correctly handled

Typical applications:

> Traction motors of railway vehicles

> Electric motors (AC/DC)

> Generators (e.g. in wind turbine generators)


› Effective prevention of electrical corrosion damage

› Superior insulation properties, with performance improved greater than 10 times

› Improved durability, with new optimized coating demonstrating 3 times the shock resistance of

conventional ceramic coated bearings

› Excellent heat dissipation

› Dimensionally interchangeable with standard bearings
