Self aligning ball bearing is the most representative rolling bearing, widely used. The bearing has the advantages of high limit speed, low friction coefficient, low manufacturing cost and simple structure. It is suitable for high speed and even high speed operation, and it is very durable and needs no regular maintenance. Easy to reach high manufacturing precision of different size and forms, used in motorcycle, precision instruments, low noise, motor cars, and general machinery industry, machinery industry is the most extensive class of bearing.
Self aligning ball bearing is mainly used to bear radial load, but when increasing the radial clearance of bearing, it can bear the combined load of radial and axial, and has the performance of angular contact ball bearing. When the speed is higher and the thrust ball bearing is not suitable, it can also be used to bear the pure axial load. Compared with other types of bearings with the same size and size as self aligning ball bearing, the friction coefficient of this kind of bearing is small and the limit speed is high. But it is not shock resistant and is not suitable to bear heavy load.
Self aligning ball bearing can be used in gearboxes, motors, household appliances, transportation vehicles, instrumentation, internal combustion engines, agricultural machinery, construction machinery, construction machinery, etc.. So, in view of this kind of bearing, what kind of advantages does it have? Lets follow the technicians of the bearings to get a detailed understanding of it.
Features of self aligning ball bearing
1, when the radial clearance of the bearing increases, it has the property of angular contact ball bearing, and can accept two alternating axial loads.
2. On the structure, each ring of self aligning ball bearing has a transverse groove raceway with a cross section of about 1/3 of the sphere perimeter. It is primarily used to accept radial loads, and also to accept certain axial loads.
3. The structure is simple, the manufacturing cost is low, and the manufacturing precision is easy to reach.
4, small friction, high speed.
5, the general use of stamping wave shaped stick frame, internal diameter greater than 200mm or high-speed running bearings, the use of car body solid cage.
Advantages of self aligning ball bearing
1, radial clearance analogy is small, radial angular contact bearings can be pre tightened with pre tightening clearance clearance, high precision;
2, most of the rolling bearings can also be subjected to radial and axial load, so the structure of the bearing combination is simple;
3, about the same size of the shaft diameter, the rolling bearing width is smaller than the sliding bearing, can make the axial structure of the machine compact;
4, under normal conditions, the efficiency of rolling bearings and liquid power smooth bearing is equivalent, but more smooth than the inclusion of smooth bearing;
5, do not require effective non-ferrous metals;
6, high level of standardization, batch production, low cost;
7, less consumption of smooth agent, easy to seal, easy to maintain.
