China wholesale self-aligning ball bearing 2318 90X190X64 mm

Product description:

Self-aligning ball bearings can withstand a larger radial load, but also can withstand a certain axial load. This type of bearing outer ring raceway
It is a spherical shape, it has self-aligning properties when the axis bending or tilt the inner ring and the centerline of the outer ring inner ring relative tilt does not exceed 1 ° ~ 2.5 °, the bearings can work.
Self-aligning ball bearings bore cylindrical and conical two. Cone-shaped hole in the taper of 1: 1 2 or 1:30. In order to strengthen the bearing lubrication performance, in the bearing outer ring on the processing of an annular oil tank and three oil holes are evenly distributed.
