First of all, size limits. Usually the bearings can be installed in space is limited. In most cases, shaft diameter (or bearings) is based on mechanical design or other design constraints. The bearing type and size selection is based on the inner bearing. Thus, the standard bearing the main list of dimensions are in accordance with international standards bore size.
Standard forms of the bearing size, the mechanical design is best with the standard bearing (the design to the bearings for easy purchase, where they said aside, there are some imported bearing-type in the model, but there are some non-standard bearings in China mainland, and in some cases there is no stock futures will be a very long time, so the bearings to be taken into consideration when options cost time and late replacement cost) bearing the load imposed on the load on the bearings, the nature, size, direction is changeable. Typically, the base-load rating list of dimensions are on display. However, radial and axial load, load, and so on are also select a suitable bearing. When the ball and needle bearing size, a needle bearing usually have a high load capacity and bear more of the vibrations and shock loads.
Speed, speed is permitted under the bearing type, size, accuracy, retainer type, load, lubrication and cooling methods, such as determining factors. Bearings are listed on the table in the standard precision bearings and grease lubrication oil to lubricate the allowed speed. Typically, deep groove ball bearings, ball bearings and cylindrical roller bearings are suitable for high-speed operation.
Bearing tolerances, the bearing size precision and accuracy is based on rotation and JIS ISO standard. For high precision and high-speed operation, the mechanical, it is recommended to use 5 or more precision bearings, deep groove ball bearings, thrust ball bearings and cylindrical roller bearings or is suitable for high-precision machinery running. When the bearing of the rigid, rolling and rolling road surface pressure, elastic deformation. Some mechanical will need flexibility to minimize distortion. Roller bearings than ball bearings produced by small elastic-variables.
In addition, in some cases bearing to impose pre-pressure to increase rigidity. This is often used for deep-groove ball bearings, to thrust ball bearings and tapered roller bearings and rings offset, shaft flex, shaft or bearing tolerance to variation, with error will result in the off-center inside and outside. To prevent excessive off-center angle, ball bearings, spherical roller bearing, or bearing is a better choice. His voice frequency and torques, and the ball bearings are based on high-precision standard manufacturing of voice and torque, so small. deep groove ball bearings, cylindrical roller bearings and to apply for low-noise, low-torque applications with special requirements.
Installation and removal, some applications need to be constantly removing and installing, to ensure that you can periodically to detect and repair. Both inside and outside the ring to be mounted bearings such as: cylindrical bearings, needle roller bearings, taper bearings 10 and for this occasion. Cone-shaped ball bearings and spherical roller bearings in the bushing, it simplifies the installation process.
