Spherical roller bearing:23068 MW33

Basic Parameters

• The initial digit "2" indicates that the bearing type is a spherical roller bearing. This means that the bearing can automatically adapt to the angular deviation between the shaft and the housing bore. It is mainly used to bear radial loads and can also bear a certain degree of axial load.
• "3068" is used to represent the size series and inner diameter size of the bearing. Specifically, its size series is composed of a specific width series and diameter series combination. These digital combinations determine the outline of the bearing and some basic size proportional relationships. For inner diameter calculation, usually the last two digits are multiplied by 5. Here, "68×5 = 340mm", so the inner diameter of this bearing is 340mm. This inner diameter size is a key parameter for the bearing to fit with the shaft.

• "M" may represent the material or structural characteristics of the bearing cage. In some bearing models, "M" can represent a solid brass cage. The main function of the cage is to evenly separate the rollers so that they can roll smoothly in the raceway, and guide the movement direction of the rollers, reducing the mutual collision and friction between the rollers. The solid brass cage has good strength and wear resistance and can adapt to various working environments and load conditions.
• "W33" is an additional code for the bearing. "W" usually indicates that there are lubricating oil grooves and three lubricating oil holes on the outer ring of the bearing. The lubricating oil groove can store lubricant, and the lubricating oil holes facilitate the entry of lubricant between the rollers and raceways inside the bearing. This design helps improve the lubrication condition of the bearing, effectively reducing friction and wear. Especially in high-speed operation or heavy-load working environments, it is very helpful for prolonging the service life of the bearing.

Bearing types and characteristics

Spherical roller bearing: 23068 MW33 belongs to spherical roller bearings. It has excellent self-aligning performance. When there is an angular deviation between the shaft and the housing hole, it can automatically adapt, avoid local stress concentration, reduce wear and prolong service life. At the same time, it can bear a large radial load and a certain axial load, and is suitable for working conditions with complex loads.

Performance highlights

• High load-carrying capacity: By optimizing the internal structure, such as the size, quantity and distribution of rollers, the bearing has a relatively high load-carrying capacity. It can stably support the operation of equipment and bear huge loads in heavy-duty equipment such as large motors and mining machinery.
• Good wear resistance: Made of high-quality bearing steel. The contact surface between the roller and the raceway is finely ground and heat-treated to form a hard and smooth surface, which can effectively resist wear. Even in harsh working environments such as cement plants and steel mills with dust and high loads, it can maintain a long service life and reduce the frequency of maintenance and replacement.
• Stable operation: Advanced manufacturing technology and strict quality control ensure that the bearing has low vibration and noise levels when rotating at high speeds. In equipment with high requirements for operational stability, such as precision machine tools and wind turbines, it can improve product quality or power generation efficiency, avoid processing accuracy reduction or equipment failure caused by vibration, and at the same time help extend the service life of other components of the equipment.

Applicable scene

• Mining machinery: Such as crushers, ball mills, conveyors, etc., which need to withstand huge impact loads and vibrations. The 23068 MW33 bearing, with its high load-carrying capacity and good wear resistance, can adapt to harsh working environments and ensure the reliable operation of equipment.
• Metallurgical equipment: In equipment such as blast furnaces and rolling mills in steel mills, facing working conditions such as high temperature and heavy load. The self-aligning performance and load-carrying capacity of this bearing can ensure the stable operation of the equipment under complex stress conditions and improve production efficiency.
• Power equipment: For example, large motors, generators, etc., which have extremely high requirements for the operation stability and reliability of bearings. The 23068 MW33 bearing can maintain low vibration and low noise under high-speed rotation and high-load conditions, ensuring the normal power generation and transmission of power equipment.
• Chemical machinery: In equipment such as reactors and centrifuges in chemical production, it may be exposed to corrosive media and high-temperature environments. The high-quality materials and good performance of this bearing can resist these unfavorable factors and ensure the safe and stable operation of the equipment.

Maintenance Tips

Lubrication aspect: Select suitable lubricants according to the working environment and operation requirements of the equipment. For high-temperature environments, high-temperature-resistant grease is required. And regularly check and replenish lubricants to maintain a good lubrication state between rollers and raceways.

Cleaning and protection: Since the application scenarios are often complex environments, attention should be paid to keeping the bearings clean. Protective devices such as sealing covers can be installed to prevent dust and impurities from entering the interior of the bearings. Also, regularly clean up debris around the bearings.
