RKB tapered roller bearings

The tapered roller bearings (TRBs) manufactured by RKB are engineered to withstand combined radial and thrust loads. Available in a rich portfolio of designs and sizes, in standardized and non-standardized dimensional series, RKB tapered roller bearings can be in metric or inch measurements and represent the state of the art. Manufactured from high hardness materials, featuring unparalleled fatigue strength and resistance to wear, RKB TRBs provide excellent performance even under severe operating conditions. RKBs single row, matched pair, double and four-row tapered roller bearings are optimized to ensure increased load carrying capacities and high stiffness in special applications. RKB Bainite Hardening Treatment (HB) and High Temperature Dimensional Stabilization (S) can be
applied on bearing rings and rollers.
 
 

Four-row tapered roller bearings

RKB four-row tapered roller bearings (FRTRB) are produced mainly in TQO and TQI con guration, in open and sealed 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 higher operating reliability and longer service life expectancy. The bearing dimensional and running accuracy conforms to ISO/ABMA/GOST speci cations.
