Angular Contact Ball Bearing

Angular contact ball bearings are used in many different industries. They are particularly useful for gearboxes, pumps, and clutches. As they carry loads in an axial direction, they are more resistant to radial forces than deep groove ball bearings. These types of bearings are available in single row or double row designs. Both are available in a variety of lubrication options and coatings.

Compared to deep groove ball bearings, angular contact ball bearings have a higher number of balls, greater axial load capacity, and improved performance at high speeds. Angular contact bearings are usually designed to be mounted on a rigid or elastic spacer. This can be accomplished in a variety of ways, including face-to-face, back-to-back, and tandem.

The most common mounting method for angular contact ball bearings is back-to-back. This arrangement allows for heavy axial loads and large momentary loads. However, it may not be able to handle radial  angular contact ball bearing loads. Face-to-face and tandem mounts are more suitable for radial loads. Alternatively, angular ball bearings can also be mounted in a triplex or quadruplex configuration. Depending on the application, angular contact bearings can be adapted to support a variety of axial loads, including combined axial and radial loads.

An angular contact ball bearing has a larger number of balls and an offset inner and outer ring. The outer ring has a partial shoulder that prevents separation between the balls. In addition, the inner ring has a grooved path. This helps to distribute lubricant and reduce noise. Aside from the outer and inner rings, a cage is included to help keep the balls stacked evenly. Usually, the cage is made of a phenolic resin or fine mesh cotton webbing.

Angular contact ball bearings are commonly used in tandem, matched pairs, and sets. There are also single and double row designs, with either a split or non-separable design. Although a single row angular contact bearing is a more economic choice, there are some advantages to using a pair of bearings.

Because of their smaller cross section and asymmetrical shape, angular contact ball bearings are ideal for thin-section applications. Thin-section bearings are typically designed for use with lead screw and ball screw applications. Additionally, angular contact ball bearings are available with Super Finished Raceways, which can improve lubricant distribution.

Angular contact ball bearings come in a variety of different designs and can be molded, cast, or machined to fit specific applications. Some manufacturers, such as SKF, have even produced molded cages for angular contact bearings.

How much grease should be added to high temperature bearings?

1. Why should high temperature resistant bearings be added with high temperature grease High temperature resistant bearings are relatively common mechanical parts in daily life, with various types. For the normal operation of high temperature bearing, a certain high temperature grease must be applied to achieve the actual effect of lubrication.

2. What effect does high temperature grease have on rolling bearings 1. High temperature grease has a very good maintenance effect on rolling bearings. 2. Its wear resistance, adhesion, heat resistance and wettability are excellent, melt carbon deposits, avoid oil stains and The agglomeration of metal wear debris improves the corrosion resistance, wear resistance and compression resistance of rolling bearings. 3. The anti-rust treatment is very good, which can reasonably improve the high-temperature oxidation resistance of rolling bearings, slow down embrittlement,

3. How much lubricating grease should be added to the high-temperature bearing to be suitable for rolling bearings. In the case of replacement and disassembly, new high-temperature grease must be introduced. The amount of lubricating grease also has certain regulations. Too much is not good, too little is not OK, so how much does it have  Deep Groove Ball Bearing Manufacturers to be? 1. The high temperature bearing is damaged by adding too much vegetable grease. Excessive application of high temperature grease will cause great damage to the rolling bearing.

(1) The larger the filling amount of high-temperature grease, the larger the friction torque. However, under the same filling amount, the friction torque of the closed rolling bearing exceeds that of the open rolling bearing. However, when the filling amount of high-temperature grease reaches only 30% of the indoor space capacity of the rolling bearing, the friction torque has not increased significantly. This is because most of the high-temperature grease in the open rolling bearing has been squeezed, and the closed rolling bearing The high temperature grease in the medium has also long been the cause of lost circulation. (2) As the filling amount of high-temperature grease increases, the temperature of the rolling bearing will rise in a parallel line. With the same filling amount, the temperature rise of the closed rolling bearing is also higher than that of the open rolling bearing. The filling amount of the high temperature grease of the closed rolling bearing should not exceed about half of its indoor space.

Therefore, if the mechanical equipment is to perform normally and fully, the rolling bearing must be properly lubricated to prevent extreme high temperature, humidity and environmental pollution. Appropriate lubrication and maintenance programs, as well as the detection of rolling bearing conditions, are the key points for rolling bearings to pass away. When the rolling bearing is damaged, it is likely to cause unpredictable shutdown of machinery and equipment, even an hour of shutdown can lead to great production damage.

How to choose deep groove ball bearings and angular contact bearings?

Differences between angular contact bearings and deep groove ball bearings. The angular contact bearing has an arc, so if the outer ring of the bearing is fixed, if it receives an axial force, then it is surrounded by these two angles, its bearing effect will be special. Yes, and  bearing  the accuracy is relatively high. Deep groove ball bearings are the most commonly used rolling bearings. It has a simple structure and is easy to use.

It is mainly used to bear radial load, but when the radial clearance of the bearing is increased, it has a certain performance of angular contact ball bearing and can bear combined radial and axial loads. It can also be used to bear pure axial load when the rotational speed is high and the thrust ball bearing is not suitable. Compared with other types of bearings with the same size and size as deep groove ball bearings, this type of bearing has a small friction coefficient and a high limit speed. However, it is not resistant to impact and is not suitable for bearing heavy loads.

What is the reason why the bearing is often burned?

Speaking of bearings, everyone must be familiar with them, but do you know why the bearings are often burned? Come and listen to the introduction of Tangshan Bearing Wholesale Factory.​​

The state of bearing burn damage refers to: the raceway wheel, rolling element and cage of the bearing heat up rapidly during rotation until discoloration, softening, deposition and damage.​​

The main cause of bearing burns is the poor lubrication of the bearing, the use of irregular lubricants, or too much or too little lubricant, all of which are incorrect.​​

Second may be excessive load (excessive preload). Speed ​​is too high. Clearance is too small. Water or other foreign objects have entered. If the above two situations are not the case, then  deep groove ball bearing the accuracy of the shaft and bearing housing is poor, and the deflection of the shaft is large. Seeing this, I think everyone wants to know the solution. First, we must study lubricants and lubrication methods, choose the right bearing lubricant, and its dosage, and correct the choice of bearings. Investigate fit, bearing clearance and preload, and improve sealing arrangements. Check the accuracy of the shaft and bearing housing. Of course, if there is a person in charge next to you, it would be better for him to operate and learn from you!
