Whether IKO bearings can be correctly selected will have a great impact on whether the main engine can obtain good working performance and prolong its service life; It plays a very important role in whether the enterprise can shorten the maintenance time, reduce the maintenance cost and improve the operation rate of the machine. Therefore, both design and manufacturing units and maintenance units must attach great importance to the selection of thin-walled bearings.
1. Select the basic type, tolerance grade and clearance of Thin-walled bearing according to the bearing working conditions (including load direction and load type, speed, lubrication mode, coaxiality requirements, positioning or non positioning, installation and maintenance environment, ambient temperature, etc.);
Through calculation according to the working conditions, stress conditions and service life requirements of IKO bearing, or select the bearing model according to the service requirements, and then check the service life;
The main factors considered in selecting IKO bearing are ultimate speed, required service life and load capacity. Other factors are helpful to determine the type, structure, dimension, tolerance grade and final scheme of clearance requirements of Thin-walled bearing.
