摘要： A tapered roller bearing for an automobile transmission is provided, which is capable of preventing very early occurrence of surface originating flaking even when loss in pre-load has occurred under severe lubricating conditions. The tapered roller bearing is constructed such that the maximum contact pressure on a raceway surface is kept less than 3000 MPa under a condition where loss in pre-load has occurred.

摘要： A wheel support device which is easy to assemble and compact in size. A pair of tapered roller bearings are mounted on the outer periphery of an axle. The pair of tapered roller bearings rotatably support an axle hub that rotates together with a wheel. A seal assembly is mounted between the outer and inner rings of one of the tapered roller bearings. The seal assembly prevents leakage of grease sealed in the axle hub and entry of muddy water from outside, and makes it unnecessary to provide a separate seal member, thus making it possible to assemble the wheel support device easily and to reduce its size.

摘要： A star-branched polyester polyol is obtained by polymerizing lactide or lactic acid, using, as an initiator, a fat and oil composed mainly of a triacylglycerol that has at least three hydroxyl groups or epoxy groups in its molecule. This polyester polyol has low crystallinity and a low melting point, and thus shows good working properties when used in various applications. Furthermore, this polyester polyol is derived from renewable resources, and, thus, it is highly desirable in view of its effectiveness in protecting the global environment and preventing fossil resources from being depleted.

摘要： The present invention is intended to increase the load capacity of a tapered roller bearing and to decrease the maximum face pressure on tine raceway surfaces without lowering the rigidity of the cage. The tapered roller bearing comprises an inner ring, an outer ring, multiple tapered rollers rollably disposed between the inner ring 2 and the outer ring 3, and a cage for holding the tapered rollers at predetermined circumferential intervals, wherein the roller coefficient γ thereof is larger than 0.94. Herein, γ=(the number of the rollers×the average diameter of the rollers)/(n×PCD).
