Abstract
A liquid lubricating tapered roller bearing device, includes: an outer ring; an inner ring including an outer end surface at a smaller diameter side; tapered rollers; and a cage located further inside in an axial direction than the outer end surface of the inner ring and including an end portion at a smaller diameter side, the end portion defining an outer end surface and an inner periphery. Inequalities X2/B≧0.010 and 0.009≦X1/D≦0.043 are satisfied where B represents a width in the axial direction of the inner ring; D represents a bore diameter of the inner ring; X2 represents a distance in the axial direction from the outer end surface of the inner ring to the outer end surface of the case; and X1 represents a dimension of a clearance in a diameter direction between the inner periphery of the cage and the inner ring.
