Four-row tapered roller bearings
RKB’s Quadruple Row Tapered Roller Bearings (FRTRB) are manufactured mostly in TQO and TQI configurations, in open or closed versions. These bearings are supplied with the required axial internal clearance (BEP) and are mainly used on the work rolls of rolling mills. The use of high-quality raw materials, special heat treatments and innovative sealing solutions is the basis of their higher operational reliability and extended service life.
