Deep groove ball bearing has the advantages of simple structure, compared with other types of easy to achieve high manufacturing accuracy, so easy to become series mass production, lower manufacturing costs, the use of very common. Select the radial internal clearance greater axial bearing Thin section bearings capacity, under purely radial force when the contact angle is zero. The action of axial force, contact angle greater than zero. General use of the stamping cage, car solid cage, sometimes also used nylon frame. Deep groove ball bearing except basic types, there are a variety of forms, such as: deep groove ball bearings with dustproof cover; deep groove ball bearings with rubber sealing ring; deep groove ball bearings with snap groove; deep groove ball bearing a large load capacity ball gap; double deep groove ball bearings. But they all share the following characteristics:
Continuous groove type 1, high precision bearings each ring in the structure of deep groove ball bearing has a cross-section of approximately spherical perimeter 1/3 roller. It is mainly used to bear radial load, also can withstand the axial load;
2, in the bearing radial clearance increases, with the nature of angular contact ball bearing, the axial load bearing two directions alternating;
3, small friction, high speed;
4, has the advantages of simple structure, low manufacturing cost, Spherical roller bearings easy to manufacture high precision;
5, the general methods of stamping cage diameter greater than 200mm, the bearing or high-speed operation, the use of the car business entity retainer.
