RKB tapered roller bearing sets are used in Polysius vertical roller mills operated by a cement producer in Brazil, where they are installed in the grinding roller assemblies.

The bearings operate under high radial and axial loads in demanding cement production conditions.

Supplied through RKB’s Brazilian partner CYH, the bearing sets consist of two single-row tapered roller bearings with an intermediate spacer. The customer has confirmed further orders for deliveries in 2027, demonstrating the reliability of the RKB solution and the continuity of the cooperation.
