Double row
BUT double row tapered roller bearings are produced in several configurations (TDO, TDOS, TDI, TDIS) to support combined forces and locate the shaft in both directions. Manufactured with a given axial clearance (BEP), they can fully exploit their potential in a variety of applications. In order to manufacture products with the highest possible resistance to fatigue and wear, BUT makes use of different bearing steel grades and special heat treatments.
