Rolling Bearings in High-Speed Passenger Traffic part2
Passenger transport today moves significantly faster than ever before, often operating on separate tracks especially designed for high-speed trains. Accordingly, high-speed rolling bearings are very important components in the bogies of
trains today. Maximum train speeds currently reach 380 km/h (236 mph) in the latest high-speed applications—80%
higher than in the earlier days of high-speed traffic. This paper presents two application examples of modern, high-speed
traffic, together with some typical bearing arrangements and housings. It provides insight regarding measures taken in the
bearing industry to meet the requirements of contemporary, high-speed traffic, and it cites important standards and regu-
lations applicable for—but not restricted to—European applications. To be precise, the focus here is on journal bearings;
information on traction motor bearings, transmission bearings and housings is included, but described in less detail.
