Introduction
81394106020 MAN Propeller Shaft Bearing is a key component in the vehicle drive shaft system. It is installed in the bottom center of the vehicle and mainly plays the role of supporting the drive shaft. In the process of vehicle operation, the drive shaft is responsible for transmitting power, and the center support bearing can stabilize the drive shaft to ensure the smoothness of power transmission. In some longer wheelbase vehicles, the drive shaft is longer, the existence of the center support bearing can effectively prevent the drive shaft due to its own weight and the centrifugal force generated during rotation and excessive bending deformation. The drive shaft center support bearing consists of bearing, bracket, rubber cushion and flingers etc.. and good sealing performance is an important guarantee that the drive shaft center support bearing can work for a long time. Sealing can prevent lubricant leakage, to ensure that the internal lubrication of the bearing is in good condition. At the same time, it can prevent the outside world of moisture, dust and other pollutants into the bearing, reduce bearing wear, corrosion and other damage occurs.
OUPIN Advantages
Our center bearings are at the cutting edge of technology. The rubber content is controlled at around 50%, with a strength of over 15 MPa and an elongation at break of over 380%. The bearing grease control range is as low as minus 35 degrees and as high as 200 degrees, with a maximum speed of 12,000 rpm and a lateral displacement of 1,000 Newton force. GCR15 bearing steel from major steel mills is used for consistent quality and long service life. We have a full range of Mercedes-Benz spare parts, if you want to know more details, please feel free to contact us, we will provide you with professional assistance.

The Features of The Oil Seal
a. Basic function of 81394106020 MAN Propeller Shaft Bearing
It is installed in the middle of the drive shaft, and its basic function is to support the drive shaft and reduce the vibration and shock caused by weight and speed. For the drive shaft with long shaft distance, the middle part will be bent because of the weight, resulting in the speed and torque of the part to produce asynchronous situation, the driveshaft support center can support the drive shaft when transmitting power to reduce vibration and shock, and the kinetic energy will be transmitted smoothly to ensure the smoothness and safety of the vehicle driving.
b. Composition and working principle of intermediate support
The driveshaft support bearings is usually composed of two main parts, namely, the support and bearing. The support is fixed on the drive shaft to support the center of the shaft; the bearing is connected to the shaft to support the relative rotation of the bearing and the shaft, and plays the role of support and vibration damping.
In the process of driving, the drive shaft and tires may produce differential speed between the tires, resulting in increased tire resistance, which plays an important role in the intermediate support, through the use of soft materials, effectively reduce the vibration and noise generated by the vehicle when driving. At the same time, the support bearings can also effectively reduce the “anti-torque” phenomenon generated by the rapid rotation of the gears, thereby reducing the loss of the drive shaft and danger.
c. Service life and inspection method of driveshaft support bearing
Driveshaft support bearing in the process of use will be due to the working environment, use of time and other factors gradually aging, limited service life. For the inspection method of the support bearing of the drive shaft, we can determine whether it needs to be replaced by observing whether its components are cracked or damaged, whether there are rust stains, deformation and other phenomena on the surface, and whether there is abnormal noise or vibration. It is generally recommended that the intermediate support of the drive shaft be inspected or replaced once when the vehicle travels 50,000-60,000 kilometers.
In short, the driveshaft support bearing is an important vehicle parts, by playing the role of support, damping and reduce the role of the drive shaft speed difference, to ensure the smoothness and safety of vehicle driving. In the daily maintenance, you also need to pay attention to the inspection and replacement of the intermediate support to ensure the smooth running of the vehicle.
