Title:
DOUBLE ROW ROLLER BEARING
Document Type and Number:
Japanese Patent JP2019100487
Kind Code:
A
Abstract:
To provide a double row roller bearing for inhibiting roller slippage from being generated between an inner ring and an outer ring even in an environment where it is easily generated.SOLUTION: A double row roller bearing 10 includes an inner ring 11, an outer ring 12, and double row rollers 13, 14 provided between the inner ring 11 and the outer ring 12. The contact loads of the rollers 13, 14 with the inner ring 11 and the outer ring 12 in a first row L1 including a plurality of first rollers 13 on one axial side can be different from those in a second row L2 including a plurality of second rollers 14 on the other axial side. A coat formed on the outer periphery of each roller included in at least one of the first row L1 and the second row L2 makes the friction coefficient of an outer peripheral face 20 of the first roller 13 greater than the friction coefficient of an outer peripheral face 23 of the second roller 14.SELECTED DRAWING: Figure 1
