Four-row tapered roller bearings

Tapered roller bearings have an outer ring and an inner ring assembly. The outer ring consists of an outer ring, and the inner ring assembly consists of an inner ring, a roller and a cage. This bearing structure adapts to combined loads and provides low friction during operation.
