The Spherical Ball Bearings

In fact the spherical ball bearings are a kind of groove ball bearing. the character of this kind of bearing is that the addendum circle outer diameter surface is a spherical surface , it can match into the concave spherical surface of the bearing seat and to adjusts the heart ,Dispute of the basic performance of the outer spherical bearing is similar to the groove ball bearing . take the spherical ball bearing that have the set screw for example .when this kind of bearing used into the shaft which rigidity week and deflection large ,because both sides belt seal packing collar so it can strictly prevent the contamination invasion
