Four-row tapered roller bearings
GIB’s four-row tapered roller bearings (FRTRB) are mainly manufactured 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 in the work rolls of rolling mills. The use of high quality raw materials, special heat treatments and innovative sealing solutions are the basis for their higher operational reliability and extended service life.
