24132 Bearing Double Row Industrial Roller Bearing Manufacturers

24132 Self-aligning Double Row Roller Bearings – Industrial Machinery Applications

Structural Features

• Double - row roller structure: It adopts a double - row roller design, which can bear large radial loads and a certain amount of axial loads. Compared with single - row roller bearings, it has a stronger load - carrying capacity.
• Self - aligning function: It has the characteristic of self - alignment. The raceway between the inner ring and the outer ring of the bearing is spherical, so that during the installation and operation of the bearing, it can automatically adapt to the deflection and misalignment of the shaft, ensure the normal operation of the bearing, and reduce the additional stress and wear caused by misalignment.

Dimensional Parameters

• Inner diameter: 160mm.
• Outer diameter: 270mm.
• Width: 109mm.
• Minimum chamfer size: 2.1mm.

Performance Parameters

• Rated dynamic load: The rated dynamic load of bearings from different brands varies. For example, the rated dynamic load of NSK's 24132CE4 bearing is 1,040,000N, while that of some other brands may be higher, such as up to 1,300,000N.
• Rated static load: It is generally around 1,760,000N.
• Limiting speed: When lubricated with grease, the limiting speed is generally about 1000rpm; when lubricated with oil, the limiting speed can reach 1300rpm or even higher. The specific value varies depending on factors such as the bearing brand and lubrication conditions.

Materials and Manufacturing

• Bearing ring material: High - quality bearing steel, such as 52100 chromium steel, is usually used. It has high strength, high hardness and good wear resistance, which can bear various loads and stresses during the operation of the bearing and ensure the service life of the bearing.
• Roller material: High - performance materials such as 52100 chromium steel are also commonly used. They are matched with the bearing ring material to ensure good contact and rolling performance between the rollers and the bearing rings, and reduce friction and wear.
• Cage material: Common materials include steel, brass, etc. The cage is used to separate the rollers evenly, guide the movement of the rollers, and ensure the stability of the rollers in the bearing. Different cage materials are suitable for different working environments and load conditions.

Application Fields

• Metallurgical industry: Such as the cooling bed rollers and blast furnace equipment in steel mills. These devices often generate large vibration and impact loads during operation and may also face high - temperature environments. The self - aligning function and high load - carrying capacity of the 24132 self - aligning double - row roller bearing can well adapt to these working conditions and ensure the stable operation of the equipment.
• Mining machinery: For example, equipment such as crushers, conveyors and vibrating screens. In the process of mining and ore processing, they need to bear huge material weight and impact force. The 24132 bearing can effectively support these loads, and even if there is a certain degree of shaft misalignment or deflection during the operation of the equipment, it can work normally, reducing equipment failures and maintenance times.
• Power industry: The 24132 self - aligning double - row roller bearing is also often used in equipment such as fans and motors. When the fan is running, due to the rotation of the impeller and the action of the air flow, the shaft will be subjected to large radial and axial loads. The motor also needs the bearing to provide stable support and good rotation accuracy during operation. The self - aligning performance and load - carrying capacity of this bearing can meet the requirements of these equipment and ensure the reliable operation of power equipment.
• Engineering machinery: Such as excavators, loaders, cranes, etc. These equipment need to frequently change actions and load during work, and the bearing needs to bear complex load conditions. The 24132 self - aligning double - row roller bearing can maintain good performance under different working conditions, improving the working efficiency and reliability of engineering machinery.
