This article mainly involves the common problems and solutions for the selection of angular contact ball bearings, such as the force of single row angular contact ball bearings, the relationship between preload and life of single row angular contact ball bearings, paired use of angular contact ball bearings.
1.Regarding the force of single row angular contact ball bearings
Single row angular contact ball bearings can bear both radial load and axial load. The bearing capacity of the axial load depends on the contact angle. But single row angular contact ball bearings can only bear one-way axial load. If the force is reversed, the bearing will fall apart.
2.The relationship between preload and life of single row angular contact ball bearings
If the preload is too large, the bearing will be overloaded, the friction will increase, and the bearing may lock up, thereby reducing the service life of the bearing. If the clearance is too large, noise and vibration will occur. At this time, the accuracy of the equipment cannot be guaranteed. At the same time, the number of rollers in the bearing will be reduced, so that there is a risk of premature failure of the bearing.
3.Paired use of angular contact ball bearings
When the axial load is too large, we often use two bearings in series to increase the load. According to the bearing force, when two bearings are needed to be used together, it is strongly recommended to use matched bearings! Matched bearings can use universal matching for easy installation. But the processing requirements are particularly high, so the price is higher, and it is suitable for high-end occasions. DB, DF and DT paired bearings can also be used to reduce the cost.
ZYS can offer both universal matching bearings and DB, DF and DT paired bearings. Please contact us by email firstname.lastname@example.org.
