High Speed Medium-Sized Ceramic/Steel Ball Bearings (Deep groove ball bearing) for EV Motor

PRODUCT APPLICATION

Our products  are used for EV MOTOR of new energy vehicles.

PRODUCT ADVANTAGES

A>The manufacturing accuracy based on P5 Level.

B>Super pure stell is used,after forging,annealing,cold rolling and then turing, in order to obtain better organiazational compactness. The harmful non-matallic inclusings are greatly reduced in our special made super clean steel

C>Diameter variation of self-researched steel ball and ceramic ball can reach 0.13um,Sa<30nm. The ceramic ball is adopted to greatly reduce the abrasion of the surface starting poin and  noise, prolong lubrication life. 
D>Composite cage suitable for high-speed operation to prevent the occurrence of abnormal wear and tear off cause by umbrella effect. 
E>All kinds of reliability tests can be carried out, based on tribology  about life analysis, can be used as a reference for machinning accuracy of support ring,steel ball and cage.

F>Clean cleaning, filtering accuracy of 0.1um, to avoid the noise caused by garbage crushing.
     a.shake cleaning---de-fat,remove most of the putty
     b.Dur-ultrasonic jet cleaning---non-fat,ultrasonic cleaning
     c.corncob roll and throw---remove the burrs
     d.five-tank washing---RO water ultrasonic,remove water-soluble garbage
     e.five-tank hydrocarbon---ultrasonic,removoe oil-soluble garbage

PRODUCT INTRUDACTION


General information of deep groove ball bearing
Deep groove ball bearing consists of an outer ring, an inner ring, a group of steel balls and a group of cages.  Deep groove ball structure is also divided into seal and open structure. The open type means that the bearing has no sealing structure. The sealed deep groove ball is divided into dust-proof seal. The dust-proof seal cover is made of steel plate, which only serves as a simple way to prevent dust from entering the bearing raceway. 

Working principle of  deep groove ball bearing
It mainly bears radial load, and also can bear axial load and radial load at the same time. When it only bears radial load, the contact angle is zero. When the deep groove ball bearing has a large radial clearance, it has the performance of angular contact bearing and can withstand large axial load. The friction coefficient of the deep groove ball bearing is very small, and the limit speed is also very high.

Characteristics of deep groove ball bearing
Deep groove ball bearings are suitable for high speed operation, and they are very durable without frequent maintenance. This kind of bearing has the characteristics of small friction coefficient, high limit speed, various sizes and forms; they are used in precision instruments, low noise motor, automobile, motorcycle and general machinery and other industries. It is one of the most widely used bearing in mechanical industry. It mainly bears radial load, and also can bear a certain amount of axial load.


Advantage:
1.Deep groove ball bearing--- able to carry high loads
2.With carbon chrome steel ball bearing/ceramic ball bearing
3.more quietly than croller bearings
4.Deep groove ball bearing----Low noise.Stable performance and durable
5.Deep groove ball bearing----Able to work in sub-zero temperatures and have low rolling resistance
6.Deep groove ball bearing----Suitable for countless applications.
