Thrust angular contact ball bearing DKLFA- In addition to two columns of O-shaped arranged rolling elements with a contact angle of 60 °, 2RS also has an additional column of rolling elements. Due to the addition of this row of rolling elements, this type of bearing can withstand higher unidirectional axial loads. This type of bearing has a stepped outer ring, so it can be easily installed on adjacent structures through flanges. The two ends of the flange are flat areas. Therefore, the radial design envelope area of adjacent structures can be very small. In order to fully utilize the bearing DKLFA- The load-bearing capacity of 2RS, their design features allow them to withstand sustained loads in the main load-bearing direction. Therefore, this type of bearing is mainly used in screw drive designs with positioning/locating bearing arrangements, tension screws, or vertically arranged screw drives. For the thrust angular contact ball bearing unit DKLFA, the tightening torque of the locking nut must be configured according to the load data.
