Product Description:

Specification of household bearings:


Bearings made by CNBM for high-grade household appliances can meet the requirements of low noise and long low noise service life. They can endure long-distance transportation. And they are applicable not only for household appliances such as air conditioners, washing machines, refrigerators, drives and dishwashers, but also for the mini-type electric appliances such as ceiling fans, dust collectors and exhaust fans.

Our ultimate goal is to provide high-quality products to our customers and the society as a whole. Through continuous exploration, development, and innovation over the years, CNBM has become a supplier of high-quality bearings for world-famous makers of household appliances such as Panasonic, Hitachi, GE< Whirlpool, LG, Samsung, and Haier.

Q:What does angle contact back to back mean?
Refers to the installation method, put it is face to face
Q:The difference between ultra high speed angular contact ball bearings and other plain bearings
The roller of angular contact ball bearings is ball, because it is a point contact (different from roller bearing line contact), so it can provide higher speed, smaller heating quantity and higher rotation precision. In some high speed spindle applications, ceramic ball hybrid bearings will also be used. Compared with the traditional steel ball, the characteristics of ceramic ball materials endow the ceramic ball bearings with high rigidity, high speed, high temperature resistance and long service life, so as to meet the customers' demand for machine tool bearing products. (flight five Rui reminded you, at present, the mainland ceramic ball mixed bearings spot less, in your choice of such imported bearings, you need to pay attention to delivery time).On the contact angle of angular contact ball bearings, 15 popular and the contact angle of 25 speed; high performance usually contact angle of 15, while the axial contact angle of 25 with high bearing capacity. Due to the effect of preload contact application of ball bearings for precision angle is very large, such as high load capacity, high rigidity of the occasion, will generally choose bearing pre medium or heavy load; and for some applications of high speed and high precision, in the early selection of imported bearings, need to pay attention to choose the appropriate pre load. Pre load is generally divided into light, medium, heavy three kinds, generally light preload is more common. In order to facilitate the use of customers, the general will have universal matching, precision angular contact ball bearings. This type of imported bearings eliminates the customer's preload adjustment, thus saving installation time.
Q:How many angles are there in angular contact ball bearings? How many degrees are they?
A stands for 30 degrees, A5 stands for 25 degrees, B stands for 40 degrees, and C stands for 15 degreesThe new Seiko NSK serves you!
Q:Two angular contact ball bearings, the use of clearance problems
Bearing in pairs need not be adjusted! The bearing is marked with letters!DB: back to backDF: face to faceDT: series connectionSU: single arbitrary combinationDU: any combination of two bearings.There is also a combination of three columns and four columns with letters on each bearing!Among them, when selecting the SU mark bearing, it is necessary to choose the bearings with the most close tolerance of the inner and outer ring diameter together. Clearance adjustment is also relatively easy.It is difficult to pair the bearings by adjusting the two common bearings together by adjusting the experience. It is best not to try in such a strict place!
Q:Angular contact ball bearings, how to judge the size of the mouth?
Yes, look at the outer ring of the bearing. The thinner end is the big one.
Q:What is the axial load of angular contact ball bearings 7202AC?
The ball bearing theory is not subjected to axial force, but it will be subjected to slight axial force in practical application because it has certain centering action and will return to its original position after the axial force disappearsThe size of the axial force to have contact with the actual working environment, stress condition of ball bearings after the axial force is equivalent to the contact angle becomes similar to the angular contact ball bearing, the axial force and clearance of bearing, the ditch radius have a great relationship.Especially the clearance, the greater the clearance, the steel ball in the axial position of the greater the scope of movement, that is, the greater the axial clearance, the axial force can also be greater, but the clearance can not be blindly large.In short, we can tell you that the axial force is much smaller than the radial force. As for how to calculate it, the contact angle can not be predicted, so there is no way to knowMore exciting questions, please click on the account login electromechanical Online - Baidu cooperation know platform
Q:What is angular contact ball bearing contact angle?
The contact angle is defined as an imaginary angle betweenA linear element added to a rolling contactAligning and a straight line perpendicular to the axis of rotationThe angle between the imaginary line of the contact between the roll and the raceway and the vertical line of the axis of rotation
Q:Can angular contact ball bearings be adjustable?
You say, of course notHave you seen when you spend RMB Mingbi useful
Q:What are the differences between angular contact bearings AC and A and C?
Angular contact bearings common suffix has AC, C and B, AC said nominal contact angle a is 25 degrees, C is 15 degrees, B is 40 degrees.
Q:What are the reasons for the use of tapered roller bearings and angular contact ball bearings?
Bearing capacity and the form of motion and load factors are different, the choice of bearings compatibility is determined by theory and practice. Visual interpretation is the role of the two bearings, see the mechanical design manual - bearing chapter
