Product Description

PRODUCT DETAILS

 

The models 11749, 11949, 12749, 12649 and 17887 are highly likely to belong to the tapered roller bearing series. The unique structure of tapered roller bearings enables them to simultaneously handle radial and axial loads. The rollers and raceways have a line contact, and the inner and outer rings can be separated, facilitating installation and later maintenance. 
Taking the common combination model LM11749 as an example, it performs well in practical applications. In the stone processing machinery field, when cutting stones, large radial and axial forces are generated, and the related tapered roller bearings of LM11749 can stably support the rotation of the saw blade, ensuring the accuracy and continuity of the cutting process. At the transmission shaft position of the injection molding machine's closing mechanism, it can well adapt to the complex combined loads brought by frequent mold opening and closing, ensuring the stability and efficiency of the closing action. 
For the 11949 model bearing, it is widely used in industrial mixed equipment. Such equipment as mixed heat exchangers and mixers, during operation, will generate certain axial and radial forces. The 11949 bearing, with its own structural advantages, can withstand these forces, ensuring the smooth operation of the equipment and achieving efficient material mixing or heat exchange. In agricultural fertilizing machinery, the 11949 bearing at the transmission shaft position can tolerate the loads brought by the frequent opening and closing of molds, ensuring the precise control of fertilization amount and the continuous operation of the machinery. 
The 12749 bearing plays an important role in the general machinery industry. In the transmission system of machine tools, it can withstand the radial and axial forces generated during gear meshing, providing stable power transmission for the machine tool's cutting processing, ensuring processing accuracy. In the transmission shaft support position of the fan equipment, the 12749 bearing can adapt to the long-term continuous operation conditions of the fan, withstand the axial force brought by the air flow impact and the radial force of the equipment's own operation, reduce equipment vibration and noise, and improve the fan's operating efficiency. 
The 12649 model bearing is often used in equipment with high precision and stability requirements. In the spindle support part of textile machinery, it can withstand the radial force and certain axial force generated by the high-speed rotation of the spindle, ensuring uniform yarn spinning and reducing the breakage rate. In some precision transmission mechanisms of optical instruments, the 12649 bearing can precisely control the rotation of the shaft, reducing errors during operation, and ensuring the high precision measurement and operation of the instrument. 
While the 17887 and similar models of bearings also play a key role in specific industrial equipment. For example, at the output shaft of small reducers, it can withstand large radial loads and certain axial forces, stabilizing the transmission of the motor's power to the working components, achieving the function of speed reduction and torque increase for the equipment. In the support of the milling shaft of some woodworking machinery, the 17887 bearing can withstand the impact radial force generated during wood milling, ensuring the quality and efficiency of milling processing. 
Although these bearings have different models, they all rely on the common advantages of tapered roller bearings to undertake important responsibilities such as stable support, force transmission and balance in equipment in various fields such as industrial production, agricultural machinery, textile, and woodworking. They are core components that ensure the normal operation of various machinery equipment.
