There are a lot of popular misconceptions when it comes to the selection of roller bearings. A good example of this is the myth regarding the load capacity of roller bearings: the specification of the load factor in the catalog and above all the overall correct technical specification are both crucial in determining the performance of a bearing. When making the right selection, the bearing clearance and fit also play a decisive role in addition to the cage.

Deep groove ball bearings with "electric motor quality" – this is how many providers market their products. Upon closer inspection, the term does not actually mean much since there are no precisely formulated, cross-manufacturer criteria for it. The comprehensive features of Findling Wälzlager’s Xspeed deep-groove ball bearing illustrate which properties are actually important and that a "noise test" is not enough.

High-speed applications require the tightest tolerances, minimal quantities of lubrication, low frictional torque, and high-purity roller bearing greases. In addition to the load caused by high speeds, the resulting increased heat development should also be taken into account. True running accuracy also plays a role with regard to a bearing’s service life. The Xspeed bearing equipment components were tailored specifically to this performance segment.

The daily work activities of design engineers include selecting and designing roller bearings. This also applies to the further specification of equipment components. This is not always easy, however, because important parameters such as fits, bearing clearance, installation type and bearing type must be taken into consideration. Findling Wälzlager has compiled and evaluated the most common design errors in quality management and gives you practical tips for preventing them.
