Development of product for railway rolling stock in the ZKL Group

In the field of rail transport, in last three years the ZKL has been focused on both the production of bearings for final customers and the supply of bearings to the spare consumption. These are in particular bearings for wagon bogies, locomotives and trams or bearings for seating of components in drive unit. Customer requirements for technical parameters and reliability increase. Nowadays, the major problem in the field of service of rail vehicles is the not unified service interval for critical components of the individual subsystem.

Within this in mind, our company pays great attention to the research and development of axle bearing with extended service intervals. In the first phase, these are Compact Tapered Bearing Units e. g.  (CTBU) 130x230, furthermore there are cylindrical roller bearings for axels WJ / WJP 130 x 240 in development and bearings with special requirements for our OEM customers as well. At present, the first prototypes of tapered units are tested on the special testing stands. Beside the development of optimized product the ZKL group in focused on the efficient production process and quality management not only in the railway production. Within these process the recertification of the plant in Klášterec nad Ohří according the new standard ISO/TS 22163 (IRIS) has been done.
