22330MB for ZP375 Oil Field Rotary Table Bearing

Self-aligning roller bearings have two rows of rollers, mainly bearing radial loads, but also can withstand axial loads in any direction.With high radial load capacity, it is especially suitable for working under heavy load or vibration load, but it cannot bear pure axial load.The raceway of the outer ring of this kind of bearing is spherical shape, so it has good centring performance and can compensate the coaxiality error.
