Thin-walled angular contact ball bearings can bear radial load and axial load at the same time, and can also bear pure axial load, with a higher limit speed.
The bearing's ability to withstand the axial load is determined by the contact angle, the contact angle is large, and the ability to withstand the axial load is high.
Thin-walled angular contact ball bearings are rarely used alone, usually they are used in two or more sets.
The following three are common matching forms:
DB back-to-back pairing
DF face-to-face pairing
DT tandem pairing
In addition, there are universal bearings that can be freely assembled.
DU can be assembled back to back, face to face, and in series.
The manufacturer will mark the paired angular contact ball bearings before shipment, which is more convenient during use and saves time for installing angular contact ball bearings.
