Product Description
The outer spherical ball bearing is actually a variant of the deep groove ball bearing. Its outer ring outer diameter surface is spherical, which can be matched into the corresponding concave spherical bearing seat to play the role of aligning.The outer spherical bearing is mainly used to bear the combined radial and axial loads which are mainly radial loads. Generally, it is not suitable to bear the axial loads alone.
Although its basic performance with deep groove ball bearings should be similar, but because of the bearing are mostly applied in mechanical rough, installation location is not accurate, the axis of the shaft with a hole to neutral, or under the condition of large axial length and deflection etc, and the bearing itself precision is not high, some structure is rough, so the performance of the actual performance comparison on the same specifications of the deep groove ball bearings to play quite a discount.For example, the outer spherical ball bearing with top wire is applied to the through-shaft with large stiffness difference deflection. The bearing, with sealing rings on both sides, can strictly prevent the invasion of dirt. It has been loaded before leaving the factory
Product Overviews
Self-aligning ball bearing has two rows of steel balls, a inner ring that has two raceways and a outer raceway in the inner spherical shape, and is provided with the function of self-aligning. The bearing can automatically compensate the concentricity error caused by the shaft deflection and housing deformation, thus suitable to the applications where the bearing seat hole can not guarantee strict concentricity. so it can still works as long as the relevant gradient between the center line of the inner ring and the same of the outer ring is within the range of 1 ° to 2.5 ° when the shaft is bent or tilted under pressure. There are two types of self-aligning ball bearings, i.e., cylindrical bore and tapered bore bearings. The taper ratio of tapered bore bearings is 1:1 or 1:30.
Self-aligning ball bearings are mainly used to carry heavy loads and impact loads, and apply to industries such as textile industry, mining, petroleum, paper making, cement, etc. and general machinery .
