SKF Bearing Type And Use Selection

 

1. Size restrictions.

Generally, the space where SKF bearings can be installed is limited. In most cases, the shaft diameter (or SKF Bearing inner diameter) is limited by mechanical design or other design. Therefore, the selection of SKF Bearing type and size is determined according to the inner diameter of SKF Bearing. Therefore, the main dimension tables of SKF bearings are compiled according to the inner diameter dimensions of international standards. Scale SKF bearings have various sizes and forms, and scale SKF bearings are used in mechanical device design Long time, the entrance of SKF bearing catalog is really good. But some non-standard SKF bearings are not available in Chinese mainland.

 

Sometimes, futures will be very long. Therefore, when SKF bearing is selected, we should consider the cost of time and the cost of later replacement. The load of SKF Bearing and the load applied on SKF Bearing vary in nature, size and direction. Generally, the rated basic load is shown in the size table. However, axial load and radial load are also important factors in selecting suitable SKF Bearing. When the size of ball and needle roller SKF Bearing is commensurate, needle roller SKF Bearing usually has high load capacity and bears large vibration Dynamic and impact loads.

SKF Bearing Type And Use Selection
2. The speed

Speed are determined according to the type, size, accuracy, cage type, load, lubrication mode, cooling mode and other factors of SKF Bearing. SKF Bearing table lists the allowable speed of SKF Bearing with scale accuracy under oil lubrication and grease lubrication. Generally, deep groove ball bearings, self-aligning ball bearings and cylindrical roller bearings are suitable for high-speed operation.

 
3. SKF Bearing tolerance

SKF Bearing dimensional accuracy and rotation accuracy are based on ISO and JIS standards. For machines requiring high precision and high-speed operation, it is recommended to use SKF bearings with precision of grade 5 or above. Deep groove ball bearings, centripetal thrust ball SKF bearings or cylindrical roller SKF bearings are suitable for machines with high operation precision. Rigid, elastic deformation will occur when the contact surface between the moving elastic body and raceway of SKF Bearing is compressed. Some machines need to minimize elastic deformation. The elastic deformation of roller SKF Bearing is smaller than that of ball SKF Bearing.

 

4. SKF Bearing shall be preloaded to increase rigidity.

This procedure is usually used for deep groove ball SKF Bearing, centripetal thrust ball bearing and tapered roller bearing. Inner and outer ring offset, shaft bending, tolerance change of shaft or SKF Bearing Housing and matching error will lead to inner and outer ring eccentricity. In order to prevent excessive eccentric angle, self-aligning ball bearing, self-aligning roller bearing, or self-aligning bearing seat are better choices. Voice frequency and torque, dynamic SKF bearings are manufactured according to high-precision standards, so voice and torque are small. Deep groove ball bearings and cylindrical roller bearings are used for occasions with special requirements for low noise and low torque.

 

5. Installation and disassembly.

In some applications, disassembly and installation are often required to ensure that inspection and maintenance can be carried out according to its place. SKF bearings with separate inner and outer rings, such as cylindrical bearings, needle roller bearings and conical bearings, are very suitable for this occasion. With the help of shaft sleeve, the installation procedure of cone hole self-aligning ball SKF Bearing and self-aligning roller bearing is also simplified.
