In the case of a double-row bearing in which rolling elements 54 of each row held by a retainer 53 are interposed between the rolling elements 54, 51 and the outer ring 52 common to both rows, when used for inner ring rotation, both rolling elements 54 The grease 55 is sealed in the center of the row. The grease 55 in the central portion enclosed gradually fills the raceway surfaces 51a and 51a.
The grease itself or the base oil is supplied to 2a so that even if the grease of the rolling element built-in portion A is discharged, the grease does not run out.

ある。However, when the outer ring rotates,
When used at high speed, not only the grease of the rolling element built-in portion A but also the central grease 55 between the two rows is stuck to the inner diameter of the outer ring 52 by the centrifugal force as shown in FIG. It is discharged to the outside of the bearing via the raceway surface 52a. In the case of high-speed rotation, this tendency is remarkable, and the grease 55 in the central portion is discharged to the outside early.
Therefore, long-time operation is difficult due to running out of grease on the raceway surfaces 51a and 52a. In the case of high-speed rotation, the amount of grease enclosed is reduced in order to suppress heat generation due to stirring resistance, so that the life is further shortened. Especially,
In the case of a tapered roller bearing, the raceway surface 52a of the outer race 52 has a slope that expands in diameter in the width direction.
The tendency for grease to be discharged through 6a is even more pronounced.

The object is to provide a double row bearing.

長時間運転が可能となる。The double row bearing for outer ring rotation of the present invention is a double row rolling bearing used for outer ring rotation, wherein a pocket forming member having a lubricant pocket is provided between both rolling element rows. Since the lubricant pocket is filled with a lubricant such as grease or solid lubricant, it can be operated for a long time without running out of lubricating oil even when it is used in high-speed outer ring rotation. In addition, it is possible to prevent heat generation due to the stirring resistance of the grease in the initial operation. When the pocket forming member is a ring-shaped member having a groove-shaped cross section opened on the inner diameter side and having a greasing hole on the side surface of the pocket and is prevented from rotating with respect to the outer ring, Utilization of centrifugal force due to rotation enables smooth lubrication of small amounts from the pocket forming member, which enables a longer operation. When a detent bolt engaging with a through hole formed on the bottom surface of the pocket forming member is screwed into a screw hole formed on the inner and outer surfaces of the outer ring to perform the detent, the detent is prevented by a simple configuration. Depending on the application, intermediate lubrication is also possible through a screw hole and a through hole with a non-rotating bolt. In addition, when the present invention is applied to a tapered roller bearing, an appropriate amount of grease or oil can be effectively supplied irrespective of the grease discharging action generated along the inclined outer raceway surface, so that a tapered roller which is difficult to operate for a long time is used. Also in the roller bearing, it is possible to operate for a long time without excessive temperature rise.
