Selection And Use Of WSBC Bearings


Wuxi Spark Bearing Co.,Ltd has enough stock for bearings,today let us learn to use of WSBC bearings 


1. Selection of bearing model: The bearing model is generally selected by the user's technical staff based on the use conditions and load bearing of the supporting products. 

Business personnel mainly understand whether the actual load of the user is consistent with the selected WSBC bearing. If the bearing fails to meet the requirements for use, the customer should be advised to change the model as soon as possible, but unless there are special products in the selection of the model, there will generally be no problems.Click here to learn more about WSBC 51130M

2. The choice of bearing clearance: When buying bearings, users generally only tell what type and grade, and rarely ask for the clearance of WSBC bearings. Business personnel must ask about the use conditions of bearings, the speed of bearings, Temperature and fit tolerance are directly related to the choice of bearing clearance. Generally, motors with speeds below 3500 rpm mostly use CM clearance. For high-temperature high-speed motors, relatively large clearances are required. After assembly, the bearing clearance will be reduced due to the expansion of the inner hole and the reduction of the outer circle. The reduction of the clearance = interference amount × 60% (except for the bearing chamber is aluminum). For example, the clearance before bearing assembly is 0.01mm, and the interference during assembly is 0.01mm, then the clearance after bearing assembly is 0.004mm. In theory, the noise and life of the bearing are at their best when they have zero clearance, but in actual operation, considering the temperature rise and other issues, the clearance of the WSBC bearing after assembly is preferably 0.002mm-0.004mm.


3. The choice of grease: The choice of grease is generally based on the bearing speed, temperature resistance, noise requirements and starting torque, etc., requiring business personnel to understand the performance of various greases.


4. Selection of bearing seal type: WSBC bearing lubrication can be divided into oil lubrication and grease lubrication. Oil-lubricated bearings are generally selected form bearings, grease-lubricated bearings are generally sealed with dust caps or rubber seals. 


The dust cover is suitable for high temperature or good environment. The seals are divided into contact seals and non-contact seals. The contact seals have good dust resistance but large starting torque, and the non-contact seals have low starting torque, but the sealing performance No contact is good.


Bearings have been professionally manufactured in industries such as automotive motor bearings, home appliance motor bearings, motorcycle bearings, health care motor bearings, etc., so that the noise and life of WSBC bearings reach the best state.Need WSBC 51232M,please kindly click here

From the perspective of the objective needs of the machine tool industry, angular contact ball bearing electric spindles, liquid (dynamic) hydrostatic bearing electric spindles, and gas bearing electric spindles are not only the focus of market development, but also the focus of academic research. Angular contact ball bearings are the most suitable high-speed rolling bearings. They have the advantages of low friction resistance, low power consumption, low cost, easy serialization and standardization. Its high speed limit, high precision, and high rigidity.


In machining centers, CNC milling machines, Lathes, internal grinders and high-speed engraving and milling machines have been widely used, and the main technical difficulty lies in improving accuracy life and reliability. The liquid (dynamic) static pressure spindle is supported by a liquid "oil film", which has a significant "error equalization effect" and damping vibration damping performance. The rotation accuracy is much higher than that of a rolling bearing spindle, which has high rigidity, low wear and long life. It has been widely used in precision ultra-precision machine tools, and its main technical difficulty lies in controlling the temperature rise and thermal deformation of the spindle at high speed. The gas FAG bearing electric spindle is supported by a "gas film", and its rotation accuracy and limit speed are higher than that of a liquid (dynamic) static piezoelectric spindle and rolling bearing type electric spindle. ) The indispensable core component of the drilling machine is that its shortcomings are low bearing capacity and high process requirements.
