BUT four-row tapered roller bearings are produced mainly in TQO and TQI configuration, in open or closed version. Supplied with the required axial internal clearance (BEP), they are mainly employed on work rolls of rolling mill applications. The use of high quality raw materials, special heat treatments, and innovative sealing solutions are at the base of their superior operating reliability and longer service life expectancy.
