3. Compact structure, light weight, and reduced axial size. 4. High precision, high speed, low wear and long service life. 5. Some bearings have the performance of self-alignment.

6. It is suitable for mass production, with stable and reliable quality and high production efficiency.

Shortcoming. 1. Loud noise. 2. The structure of the bearing seat is relatively complex. 3. The cost is high.

Basic features of ball bearings:

Ball bearings have low friction coefficient, low vibration and noise, high ultimate speed, and high precision, making them the preferred bearing type for users when selecting models. However, this kind of bearing is not resistant to impact, not suitable for bearing heavier loads, among which the deep groove bearing structure is simple, easy to use, is the largest production batch, the most widely used type of bearing. It is widely used in automobiles, home appliances, machine tools, motors, pumps, agricultural machinery, textile machinery and many other fields.

Its output accounts for more than 70% of the total output of bearings, and it is the highest output in China, the most common and cheapest type of bearing.

There are many types of bearings, and you still have to buy or customize them according to your needs.

1 Rolling bearings.

The coefficient of friction is higher than that of plain bearings.

Small and high transmission efficiency. Generally, the friction coefficient of plain bearings is, while the friction coefficient of rolling bearings is only;

2. Rolling bearings have been standardized, serialized and generalized, suitable for mass production and high-quality, and are very convenient to use and maintain;

3. Bearing steel for rolling bearings.

Manufactured, and after heat treatment, therefore, rolling bearings not only have high mechanical properties and long service life, but also can save the most expensive non-ferrous metals used in the manufacture of sliding bearings;

4. The internal clearance of the rolling bearing is very small, and the machining accuracy of each part is high, so the running accuracy is high. At the same time, the rigidity of the bearing can be increased by preloading. This is very important for precision machinery;

5. Some rolling bearings can bear both radial and axial loads, so the structure of the bearing support can be simplified;

6 Due to the high transmission efficiency of rolling bearings, heat is generated.

Less, therefore, the consumption of lubricating oil can be reduced, and lubrication maintenance is more convenient;

7 Rolling bearings can be easily applied to shafts in any orientation of space.

Ball bearing: a kind of rolling bearing, the ball is installed in the middle of the inner steel ring and the outer steel ring, which can bear a large load. Also called ball bearings.

I'm surprised that the two people upstairs can copy this lot of information, don't ball bearings and ball bearings mean the same thing? It's all ball bearings, and the landlord's problem is not right.

The advantages of sliding bearings are that compared with sliding bearings, rolling bearings have the advantages of low frictional resistance, sensitive starting, high efficiency, simple lubrication and easy replacement. The disadvantages of plain bearings are poor impact resistance, noise at high speeds, and working life is not as good as that of liquid-lubricated plain bearings.

Rolling bearing. The main features are:

1. Small friction damping (compared with non-liquid friction sliding bearing, flexible starting.)

2. It can bear radial and axial loads at the same time, simplifying the supporting structure;

3. The radial clearance is small, and the clearance can also be eliminated by preloading method, so the rotation accuracy is high.

4. Good interchangeability and easy maintenance.

The main features of plain bearings are:

1. Stable work and no noise;

2. High rotation accuracy;

3. Small friction loss during liquid lubrication;

4. Small radial size;

5. High bearing capacity.

First, the nature is different.

1. Roller bearing: one of the components widely used in modern machinery.

2. Ball bearing: a kind of rolling bearing, the ball ball is installed in the middle of the inner steel ring and the outer steel ring, which can bear a large load.

Second, the principle is different.

1. Ball bearings: Determine the relative position of two components (usually shaft and housing) to ensure that they rotate freely while transferring the load. At high speeds (e.g. in gyroscopic ball bearings), this application can be extended to include free rotation with virtually no wear on the bearings.

2. Roller bearing: rely on rolling contact to support the rotating parts. Different rolling bearings can withstand different radial and axial forces. When selecting rolling bearings, the selection should be based on the specific working conditions.

1. Ball bearing is a kind of rolling bearing, which installs the spherical alloy steel ball in the middle of the inner steel ring and the outer steel ring to reduce the friction in the process of power transmission and improve the transmission efficiency of mechanical power in a rolling way. Ball bearings cannot withstand large heavy loads and are more common in light industrial machinery. Ball bearings are also called ball bearings.

2. Rolling bearing (rollingbearing) is a precision mechanical element that changes the sliding friction between the running shaft and the shaft seat into rolling friction, thereby reducing the friction loss. The rolling bearing is generally composed of four parts: the inner ring, the outer ring, the rolling element and the cage, and the function of the inner ring is to cooperate with the shaft and rotate together with the shaft;

The outer ring is to match with the bearing seat and play a supporting role; The rolling element is evenly distributed between the inner ring and the outer ring with the help of the cage, and its shape, size and number directly affect the performance and life of the rolling bearing; The cage can evenly distribute the rolling elements and guide the rolling elements to rotate for lubrication.

There is no specific difference between the two, ball bearings are a type of rolling bearings.

The spherical alloy steel ball is installed in the middle of the inner steel ring and the outer steel ring to reduce the friction in the process of power transmission and improve the transmission efficiency of mechanical power by rolling mode. Ball bearings mainly consist of four basic elements: balls, inner rings, outer rings and retainers.

The structure of a rolling bearing is made up of parts:

1. The outer ring is installed in the bearing seat bore, and generally does not rotate.

2. Inner ring - installed on the journal and rotates with the shaft.

3. Rolling element - the core element of the rolling bearing.

4. Cage - evenly separate the rolling elements to avoid friction.

Support the rotating shaft and the parts on the shaft, and maintain the normal working position and rotation accuracy of the shaft, the rolling bearing is easy to use and maintain, reliable to work, good starting performance, and has a high bearing capacity at moderate speed.

There are many kinds of rolling elements of rolling bearings, such as: round ball, cylindrical, thin cylindrical type (needle roller), conical, their names are: ball bearing, cylindrical roller bearing, needle roller bearing, tapered roller bearing. Ball bearings are just one of the varieties of rolling bearings.

Ball bearings are a kind of rolling bearings, which include ball bearings, roller bearings, needle roller bearings, and so on.

Rolling bearings include roller bearings, needle roller bearings and ball bearings, roller bearings are used for occasions with large radial pressure, needle roller bearings are suitable for occasions with large radial pressure and small speed, and ball bearings are suitable for occasions with small radial pressure and high speed.

The rolling elements are cylinders and spheres, and the balls are also rolls.

Ball bearing is a kind of rolling bearing, the ball ball is installed in the middle of the inner steel ring and the outer steel ring, which can bear a large load. Also called ball bearings. It is used in places where the carrying capacity is not large and requires economic cooperation.

Roller bearings are rolling bearings that use short cylindrical, tapered or waist drum rollers as rolling elements. There are mainly structural types such as centripetal short cylindrical rollers, double-row centripetal spherical rollers, tapered rollers and thrust rollers. These rollers are mainly used in cylindrical roller bearings, but roller assemblies can also be used directly in machinery.

These rollers are standardized in size and can be used as commercial rollers for design and user selection.
