The freedom from maintenance with a long operating life is become increasingly important for spherical plain bearings in railway vehicles. Here, INA maintenance-free spherical plain bearings in all designs are used successfully. These bearings are characterized by a high load carrying capacity, as well as extraordinary reliability and long life not only in the case of smaller dimensions for door systems and medium-size bearings for tilting technology, but also larger dimensions, for example, in couplings.
Maintenance-free standard spherical plain bearings with ELGOGLIDE® sliding fabric are used for the main tilting mechanism of the tilting system that can achieve a service life of more than 1.2 million kilometers without requiring maintenance.
Maintenance-free special plain bearings with specially-designed bellows are used in highly-dynamic carriage body stabilizing systems (e.g. anti-roll bars).
