Deep groove ball bearing inner and outer ring raceway are arc-shaped deep groove, the channel radius slightly larger than the radius of the ball. Mainly used to bear radial load, can also bear a certain axial load. When the bearing radial clearance increases, with angular contact ball bearing function, can withstand greater axial load, but also for high-speed rotation. Bearings in the shell hole and axis relative tilt 8 ~ 16, still work properly, but affect its service life. In the high speed and should not be used in the case of thrust ball bearings can be used to bear pure axial load of such bearings.
Deep groove ball bearings are generally used by a two-part synthesis of steel stamping cage, but large-size or high-speed bearings are used solid cage, the cage with the same as the ball cage guided by the ball, high-speed deep groove ball bearings to maintain The frame is usually guided by the inner or outer ribs.
With the same size of other types of bearings, deep groove ball bearing friction coefficient is small, vibration and noise is also low, high speed limit, high precision, is the user selection of the preferred bearing type. However, such bearings are not resistant to shock and are not suitable for heavy loads.
Deep groove ball bearing structure is simple, easy to use, is the largest production volume, the most widely used class of bearings. Widely used in automobiles, household appliances, machine tools, motors, pumps, agricultural machinery, textile machinery, and many other fields. Its production accounted for more than 70% of total bearing production, is Chinas highest production, use the most popular and cheapest type of bearing.
Deep groove ball bearings are the most common type of rolling bearing. The basic type of deep groove ball bearings consist of an outer ring, an inner ring, a set of steel balls and a set of retainers. Deep groove ball bearing type has single row and double row two, single row deep groove ball bearing type code is 6, double row deep groove ball bearing code 4. Its structure is simple, easy to use, is the most common production, the most widely used class of bearings.
Deep groove ball bearings mainly bear radial load, can also bear radial load and axial load. The contact angle is zero when it is subjected to radial loads only. When the deep groove ball bearings have a larger radial clearance, with angular contact bearing performance, can withstand greater axial load, deep groove ball bearing friction coefficient is very small, the limit speed is also high.
Deep groove ball bearing structure is simple, compared with other types of easy to achieve high manufacturing accuracy, so easy to series into mass production, manufacturing costs are also lower, the use of very common. Deep groove ball bearings in addition to the basic type, there are a variety of variant structures, such as: deep groove ball bearings with dust cover, with rubber seals deep groove ball bearings, groove deep groove ball bearings Ball notch large load capacity of deep groove ball bearings, double row deep groove ball bearings
Deep groove ball bearings can be used for gearboxes, instrumentation, motors, household appliances, internal combustion engines, transport vehicles, agricultural machinery, construction machinery, construction machinery, yo-yo, etc.
Deep groove ball bearings in the machine is mainly from the support and reduce the role of friction, so the accuracy of deep groove ball bearings, noise and so are directly related to the use of machinery and life. But the business always always encounter some customers that use the best deep groove ball bearings or deep groove ball bearings imported its efficiency is not high, which relates to the use and selection of deep groove ball bearings. Some people may say that the use and selection of deep groove ball bearings that is the users business, I just want what the user what to sell. But as a qualified sales staff in addition to proficient in their own product knowledge but also proficient in the use of the product, that is, the sale of doctors, according to the users matching product performance, use the conditions to choose the best supporting deep groove ball bearings. This is the worlds major companies popular professional manufacturing and sales, this approach has been implemented in the people of the Group has achieved good results.
Because the type of deep groove ball bearings and more wide range, the following will mainly use the most widely used deep groove ball bearings deep groove ball bearings and the choice of some analysis. Hope to deep groove ball bearing less understanding of deep groove ball bearings can deepen understanding.
