BFS-8023 A-Thrust tapered roller bearing-FGFA bearings

BFS-8023 A Single direction tapered roller thrust bearing

Thrust tapered roller bearings are transmission components specifically designed for heavy-duty unidirectional axial loads. Their core comprises a housing ring, shaft ring, tapered rollers, and a cage. Through the matching of tapered rollers with inclined raceways, they offer a large bearing surface area and high rigidity, enabling stable support of substantial unidirectional axial forces while also accommodating minor radial loads.
