This SKF BVN-7151A bearing is one of the parts for repairing THE C190 air end motor
SKF BVN-7151A bearings can be divided into sliding SKF bearings and rolling SKF bearings according to the differences in specific structure and working properties
SKF BVN-7151A bearing is a kind of precision component, widely used in various fields, according to the structure or type is divided into many kinds, and according to the friction properties to classify the most common is rolling bearings and sliding bearings, the two are also different. Obviously, rolling bearings have less friction resistance than sliding bearings, and they start quickly and have high efficiency. This is the biggest advantage of rolling bearings compared with sliding bearings.
But there are also disadvantages, that is, the size is large and the shock absorption capacity is weak, the life is short when the high-speed operation, and the long use will also send out a large abnormal sound. There is also a most essential difference between SKF rolling bearings and sliding bearings, that is, rolling bearings are surface contact, and sliding bearings are point contact. Rolling bearing has large contact surface, simple structure, easy operation and easy disassembly; Sliding bearings have high requirements for lubrication.
Bearing installation before preparation work
The installation of bearings should be carried out in a dry and clean environment.
Preparations before installation:
Different installation methods are adopted according to different bearing sizes and application environments.
Prepare the necessary parts, tools and equipment for installation;
Prepare all parts for installation and clean them thoroughly before installation.
Check the size and shape accuracy of all parts to be installed as per drawing.
Note: Do not unpack the bearing before the installation preparation is completed, so as not to contaminate the bearing.
