Frequently asked questions about this product
1. Why did the purchased single-row angular contact bearing fall apart during installation?
Single-row angular contact ball bearings can only bear axial loads in one direction. The installation process must be correctly installed according to the load direction. If the installation direction is wrong, the bearing will not be able to effectively bear the axial force, causing the bearing to fall apart.
2. Which is better, DB or DF pairing?
DB and DF pairings each have their own advantages: Back-to-back (DB) installation: The wide end faces of the two bearings are opposite, and the contact angle line spreads along the direction of the rotation axis, increasing the radial and axial bearing angle rigidity, and the maximum anti-deformation ability.
Face-to-face (DF) installation: The narrow end faces of the two bearings are opposite, and the contact angle line converges toward the direction of the rotation axis. The bearing angle rigidity is small, but the preload can be increased.
