This angular contact ball bearing supports axial loads acting in both directions thanks to its double direction design, combined with the ability to accommodate the corresponding radial loads within the design limits of the bearing. The bore diameter is 40.0 mm, outside diameter 100.0 mm, and width 34.0 mm, with a net mass of 1.466 kg. Mounting is done via screw connection through the mounting holes machined into the bearing rings, which simplifies axial positioning without additional locking elements. The bearing is sealed on both sides (2RS), which keeps the internal grease fill protected from contamination and retains lubricant during operation, reducing the need for frequent relubrication. The double direction axial arrangement allows the bearing to take up alternating or combined axial loads from either side of the shaft, making it suitable for spindle and screw drive arrangements where precise axial guidance under load reversal is required.
