Bearings for Tilting Technology

Rail vehicles with tilting technology reach considerably higher speeds on conventional routes than vehicles without tilting technology. This means that journey times are shortened and makes intercity transport more attractive. INA bearings are used in the main tilting mechanism of the rail vehicles, in stabilizing systems such as anti-roll bars and in the drive units for the tilting motion. Yoke Type Track Roller Units Yoke type track roller units are complete assemblies consisting of one shaft and two yoke type Track rollers. Two yoke type track roller units per bogie support the bogie bolster in each case that, as the main supporting element, enables the tilting motion of the railcar body. The special INA yoke type track rollers are protected against corrosion with Corrotect® and have special Seals as effective protection against contamination and have a long operating life.

Cylindrical Roller bearings with Annular Grooves The full-complement locating bearings can support not only radial forces but also axial forces in both directions. They can be fixed using annular groves and are protected against contamination and water spray by lip seals on both sides. Since the units can be relubricated and they are protected against corrosion with Corrotect®, they present a long-term reliable solution with a high load carrying capacity. Needle Roller/ Thrust Cylindrical roller bearings These units are used in the drive units for the tilting system and are characterized by a high level of reliability and a long operating life. They consist of an outer ring with radial and axial raceways, two shaft locating Washers, an inner ring, a radial needle roller and cage assembly and two thrust cylindrical roller and cage assemblies.
