Deep groove ball bearings are bearing the most common type . The basic model consists of a deep groove ball bearing outer ring, an inner ring, a ball and a group holding structure into . Deep groove ball bearing type has two kinds of single and double row , single row deep groove ball bearing type code 6 , double row deep groove ball bearings code is 4. Its structure is simple , easy to use , the production of the most popular , the most widely used class bearings.
Works
Deep groove ball bearings mainly take radial load , but also to support radial and axial load . When the only radial loads , the contact angle is zero. When the deep groove ball bearings with a larger radial clearance , with angular contact bearings can bear large axial load, deep groove ball bearing friction coefficient is small, the speed limit is also high.
Bearing structure
Deep groove ball bearing structure is simple , easy to achieve compared with other types of manufacturing high precision , so easily into a series of high-volume , lower manufacturing costs , the use of very common . In addition to the basic type of deep groove ball bearings , there are a variety of structural variants , such as: Shielded deep groove ball bearings with rubber seals of deep groove ball bearings with snap groove deep groove ball bearings, have installed ball gap large load capacity of deep groove ball bearings , double row deep groove ball bearings.
Bearing Type
1 , single row deep groove ball bearings
2 , with a dust cover single row deep groove ball bearings
3 , with a dust cover , a ring of single row deep groove ball bearings
4 , with snap groove and snap ring on the outer ring of single row deep groove ball bearings
5 , ball gap deep groove ball bearings
6 , double row deep groove ball bearings
Bearing characteristics
Deep groove ball bearings are the most representative of rolling bearings , widely used. Suitable for high speed or high speed operation , and very durable, without regular maintenance. This kind of bearing friction coefficient is small , extreme high speed , simple structure, low cost, easy to achieve high manufacturing precision. Size range and diverse , used in precision instruments, low noise motors , automobiles, motorcycles and general machinery industries, the machinery industry, the most widely used type of bearings . The main radial load , but also can withstand a certain amount of axial load.
When you select a larger axial radial clearance increased carrying capacity , subject to pure radial force when the contact angle is zero. The axial force, the contact angle is greater than zero. Commonly used stamping ribbon cage , machined solid cage, sometimes with nylon frame .
Deep groove ball bearings mounted on the shaft , the axial bearing clearance range , limit the two directions of axial displacement of shaft or housing , it can be positioned in the bi- axial . In addition , the class also have some bearing self-aligning capability , when compared to shell -hole tilt 2 'to 10' , still work , but has some influence on bearing life . Deep groove ball bearing cage mostly steel stamping ribbon cage , a large multi-use vehicles bearing metal solid cage.
Deep groove ball bearings are the most commonly used rolling bearings . Its structure is simple , easy to use. Mainly used to bear radial load, but increase the bearing radial clearance , with certain features of the angular contact ball bearings can withstand radial and axial joint load . When should not be used in high speed and thrust ball bearings , can also be used to bear pure axial load . Deep groove ball bearings with the same sizes of other types of bearings , such bearings friction coefficient, high speed limit. But the impact of intolerance , unfit to bear heavy loads [ 1 ] .
