ETC EVO Angular ContactBall Bearings
Single row angular contact ball bearings are mainly used for
undertaking combined radial and axial loads, and also for pure
radial load.
These bearings have a high rotating speed.
and other types of bearing steel, while balls are adopting GCr15 or ceramic

Types and Characteristics of Bearing Arrangements
- DB Arrangement: It can transmit radial forces as well as axial forces on both sides. Load capacity of the loment load is big (Mount inserts, Back to Back)
- DF Arrangement: It can transmit radial forces as well as axial forces on both sides. Load capacity of the loment load is small (Mount in sets, Face to Face)
- DT Arrangement: It can transmit radial forces as well as axial forces on one side. Axial load capacity is larger than others (Mount in sets, Tandem)
