Application and Types of guide bearings in steel equipment

Oct 20, 2023

The main function of the guide bearing is to guide and support the rotating shaft to ensure its smooth operation. In rotating or sliding bearings, pilot bearings can withstand high loads and friction while also helping to reduce vibration and noise. In addition, guide bearings can also be used for axial positioning to control the movement of the shaft and ensure the normal operation of machinery and equipment. In some applications, guide bearings can also act as a seal to prevent dust and other impurities from entering the interior of the bearing.

Please note that different types of bearings have different functions and characteristics. Choosing the appropriate bearing requires judgment and decision-making based on the specific use occasion.

In the steel industry, commonly used guide bearings usually include the following types:

Four-row cylindrical roller guide bearing: This kind of bearing consists of four cylindrical rollers and is usually used to support rotating shafts. It has the characteristics of high precision and low friction. The outer ring function of the four-row cylindrical roller guide bearing cooperates with the inner ring and rollers to withstand radial load and axial force and can adapt to high-speed rotation. In steel mills, this kind of bearing is usually used in equipment such as various rolling mills and continuous casting machines.

Double-row tapered roller guide bearing: This kind of bearing consists of two tapered rollers, has high stiffness and load-bearing capacity, and can withstand radial load and axial force. Both the outer ring and inner ring of the double-row tapered roller guide bearings cooperate to adapt to high-speed rotation. In steel mills, this type of bearing is commonly used as support bearings for various continuous casting machines and finishing machines.

Deep groove ball bearing guide bearing: This kind of bearing cage is guided by the ball, like the stamped cage. The inner ring or outer ring rib usually guides the cage of high-speed deep groove ball bearing.

Double-row ball bearing guide bearing: This kind of bearing consists of two ball bearings, has the characteristics of high precision and low friction, and can withstand radial load and axial force. The outer ring of the double-row ball bearing guide bearing cooperates with the inner ring to adapt to high-speed rotation. In steel mills, this type of bearing is commonly used as support bearings for various continuous casting machines and finishing machines.

Angular contact ball bearing guide bearing: This kind of bearing is composed of an angular contact ball bearing and an outer ring. It has the characteristics of high precision and high speed and can withstand radial load and axial force. Both the outer ring of the angular contact ball bearings guide bearing matches the inner ring and can adapt to high-speed rotation. In steel mills, this kind of bearing is usually used as the support bearing of various finishing mills and tension leveling machines.

In short, there are many types of guide bearings used in steel plants, and different bearings have different characteristics and application ranges. According to the characteristics and requirements of different equipment, selecting the appropriate type of guide bearing can effectively improve the performance and stability of the equipment, thereby improving the production efficiency and quality of the steel plant.

Guide bearings play an important role in steel equipment. In the steel production process, guide bearings are used to support rotating shafts and ensure high-precision operation of machines. Guide bearings are vital to steel equipment. In this article, we'll explore their role in detail.

Support the rotating shaft: The guide bearing is used as a supporting element to support the rotating shaft and keep the rotating shaft stable during operation. Compared with ordinary bearings, guide bearings have higher stiffness and lower friction torque, which can provide a better support effect.

Improve machine accuracy: The accuracy and stability of the guide bearing affect the accuracy of steel equipment. Guide bearings can reduce the runout and vibration of the rotating shaft, thereby reducing machine errors and improving machine accuracy. It is crucial for the production of steel equipment, as high-precision machines produce higher-quality steel products.

Bear radial load: The guide bearing can bear radial loads, such as axial force and centrifugal inertia force. It helps ensure that steel equipment remains stable during operation and can transmit power efficiently.

Reduce noise and vibration: The design of the guide bearing is usually more optimized and can reduce noise and vibration during machine operation. It is critical to the performance and working environment of steel equipment, as low-noise and low-vibration machines increase productivity and reduce the impact on the surrounding environment.

Easy maintenance: Guide bearings are usually easy to replace, making it convenient for steel equipment maintenance personnel to perform maintenance. When the guide bearing is worn or damaged, the entire bearing assembly can be easily replaced without disassembling the entire equipment, saving a lot of time and cost.

In short, guide bearings play a key role in steel equipment. They can provide high-precision support, withstand radial loads, reduce noise and vibration, and facilitate maintenance. By using guide bearings, steel companies can improve production efficiency, reduce costs, and produce higher-quality steel products.
