Thanks to the adoption of the latest manufacturing technology, that enables to reach tighter allowances, the RKB Group has developed a new production protocol for TQO/TQOS bearings specifically designed for high speed applications, particularly cold rolling mills for the steel and aluminum industries. The RKB special protocol for high speed four-row taper roller bearings (unsealed and sealed) permits to extend the service life of TQO/TQOS operating in such critical conditions.
