Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a railway vehicle bearing unit preventing the occurrence of fretting abrasion by avoiding the deviation of contact bearing pressure between an inner ring and a rear cover. SOLUTION: The railway vehicle bearing unit includes a double row bearing 3 to be fitted to an axle 1, and the rear cover 23 to be fitted to the axle 1 in contact with the axle axial inside end face of the inner ring 12 of the double row bearing 3. A contact portion 23a of the rear cover 23 with the inner ring 12 is formed by a curved surface. COPYRIGHT: (C)2011,JPO&INPIT
