Identifying and repairing rolling bearing damage

Rolling bearing damage can have a wide variety of causes and is not necessarily caused by a faulty original product. However, most companies are unable to carry out a detailed damage analysis – good thing Findling Wälzlager’s experts can provide further assistance here: Damage analysis is part of the service portfolio. Findling Wälzlager acts as an independent partner that looks into the causes of the ball bearing defects and helps solve problems.

How do I know if I’ve chosen the right bearing clearance class – C0, CN, CM, C2, C3...? An article from our konstruktiv! series. Tips series.

It is not the load rating but the right overall technical specifications that are decisive when it comes to the service life and performance of roller bearings.

Xforce housing bearing

Housing bearings for heavy-duty applications are now also available as part of the Findling’s special Xforce product range. They can also handle high loads and rough ambient conditions and are therefore optimally suited for use in conveyor systems, construction machinery, plant construction, agriculture or classic heavy engineering, for example.

air handling housing bearings

Housing bearings with higher speed limits and less heat development. Optimum for thermal, ventilation and air-conditioning technology, systems for air filtration or cleaning, compressors or centrifuges.

agricultural machinery

Bearing types frequently used in agricultural machines include deep-groove ball bearings, angular contact ball bearings and tapered roller bearings, as well as, in particular, housing bearing units.
