Spherical Roller Bearing 22211MBK 22211MB/W3

Two groove of the inner ring and outer ring rolling sphere of dao, between the fractal roller equipped with drums of bearings. Outer ring groove of curvature of the center
And bearing center is consistent, so with automatic self-aligning ball bearing the same tone heart function .In the shaft, shell buckling, can appear be automatic adjustment, not increase bearing burden. Self-aligning roller bearings can
Radial load and two direction of the axial load. Radial load capacity, apply to a heavy load, impact load conditions. Inner circle of tapered bore diameter is installed, can be directly bearing. Or use tight
fxed sets, remove pipe shall be fitted on cylinder shaft. Keep rack stamping steel cage, polyamide forming keep frame and copper alloy system maintains a car.
At the same time also can withstand the axial load. Such bearing outer ring groove is spherical shape, it has self-aligning performance, when the shaft bending stress and tilt centerline and outer ring that inner circle centerline relative tilt does not exceed 1 ° ~ 2.5 °,
Bearing can still work.
Self-aligning ball bearings aperture has two cylindrical and cone. Conical taper of inner hole 1:1 2 or 1:30. In order to strengthen the lubrication performance, in bearing outer ring tanks and three in processing
