    摘要: A roller bearing assembly is provided which is adapted to enhance lubrication performance for preventing seizure and for reducing frictional torque during rotation. The roller bearing assembly includes an inner ring (1), an outer ring (2) and a roller (3) rollably interposed between these inner and outer rings. The inner ring (1) is formed with a rib (4) making contact with a greater end face (7) of the roller (3) for guiding the rolling motion of the roller (3). A recess (5) is formed centrally of the greater end face (7) of the roller (3). A stopper member (6) for preventing oil invasion is fitted in the recess (5) of the roller (3).

    摘要: A tapered roller bearing includes an outer ring, an inner ring including a large rib surface formed into a concavely curved surfaced recessed in an axial direction, and a plurality of tapered rollers. R1/R2 is in the range of 0.07 to 0.8 where R1 represents radius of curvature of a large end face of the tapered roller and R2 represents a radius of curvature of the concavely curved surface. An arithmetical mean roughness the large end face is in the range of 0.01 to 0.03 μm. A total crowning amount is 50 μm or larger, an outer ring crowning rate, which is a rate of the outer ring crowning amount on the total crowning amount, is 40% or larger, and a roller crowning rate, which is a rate of two times of the roller crowning amount on the total crowning amount is 20% or smaller.
