摘要：
In a tapered roller bearing, LWR/DW is in the range of 1.1 to 1.7 where LWR represents a roller effective length of tapered rollers and DW represents a roller mean diameter of tapered rollers. RCO/LRO is 30 to 150, and RCI/LRI is 50 to 260 where RCO represents a crowning radius of an outer ring, LRO represents a raceway length of the outer ring, RCI represents a crowning radius of an inner ring and LRI represents a raceway length of the inner ring. The following expressions are satisfied: 20°≦α≦30°, and α−0.87γ−0.334≦BK≦α−0.87γ−0.167, where α represents a raceway angle of the outer ring, γ represents a roller angle of the tapered rollers, and BK represents a rib angle of a large rib portion of the inner ring.
