Product Description

 

Spherical roller bearings are a kind of rolling bearings with excellent performance and wide applications. The following mainly introduces their content from aspects such as structure, characteristics, and applications: Structure Inner ring: It is closely matched with the shaft. There are two raceways on the inner ring. The shape and size of the raceways are designed to have a good contact with the rolling elements (spherical rollers), so as to ensure the effective transmission of loads and guide the movement of the rolling elements. The inner diameter of the inner ring is determined according to the diameter of the shaft it is matched with, in order to achieve reliable installation and operation. Outer ring: Usually installed in the hole of the bearing seat or other supporting components, the raceway of the outer ring is spherical. This is a key structural feature that enables the spherical roller bearing to achieve the self-aligning function. The spherical raceway allows the inner ring and the rolling elements to tilt relative to the outer ring within a certain range, thus compensating for the influence caused by the deflection deformation of the shaft or installation errors. Rolling elements: Generally, they are symmetrical double-row spherical rollers. The shape of the rollers is specially designed, usually drum-shaped or similar, to adapt to the spherical raceway of the outer ring and the double raceways of the inner ring. The rolling elements roll between the raceways of the inner and outer rings, bearing and transmitting radial and axial loads. Cage: Its function is to evenly separate the two rows of rolling elements to prevent collisions and friction between the rollers. At the same time, it guides the rolling elements to roll correctly in the raceways, ensuring the smooth operation of the bearing. Common materials of the cage include metals (such as stamped steel, solid copper alloy, etc.) and non-metals (such as plastics, etc.). There are also various structural forms, such as wave-shaped cages and window-type cages.,

Introduction of Spherical Roller Bearings
Spherical Roller Bearings are a type of rolling bearing with an automatic self-aligning function. It can withstand a large radial load while also being able to bear a certain axial load. The characteristic of this bearing is that its rollers are in a drum shape (spherical shape), and the outer raceway is spherical. Therefore, it has the function of automatic self-aligning, which can compensate for misalignment problems caused by installation errors or shaft deflection.

Main features:

1. Automatic self-aligning ability: Due to the spherical design of the inner and outer raceways, even if the shaft has a slight bend or there is a deviation in the installation, the bearing can still work normally.
2. High load-carrying capacity: Spherical Roller Bearings can withstand large radial and axial loads, and are suitable for heavy-duty working conditions.
3. Stable operation: Even under high-speed operating conditions, it can maintain good performance.
4. Various design forms: Common designs include symmetrical rollers, asymmetrical rollers, and sealed types, etc., to meet different application requirements.

Application fields:
Spherical Roller Bearings are widely used in industrial equipment and machinery, such as:

• Paper-making machinery
• Speed reducers
• Wind turbines
• Mining machinery
• Metallurgical equipment
• Conveyor equipment
•
