BSB4090-SU-XL – Axial angular contact ball bearing (single-sided) for defined positioning accuracy in a compact installation space
Quality that safeguards processes
Under axial load in one direction, the geometry ensures rigid guidance and smooth running. Furthermore, the speed capability remains high, and the axial position is clearly defined. This results in smooth, reproducible operation during the process. If axial loads need to be transmitted in both directions, a bearing pair or a double-sided design is used.
Design and manufacturing quality
The offset raceways with a large contact angle (e.g., 60°) ensure high axial stiffness. At the same time, precise cage guidance and finely machined raceways keep friction low and ensure smooth running. Therefore, precise alignment of the components directly impacts running quality, as angular adjustability is limited. Furthermore, the P4S tolerance class supports dimensional accuracy and repeatability. A polyamide cage guides the balls precisely and stabilizes the running motion. The cylindrical bore also simplifies assembly and fit selection. Thus, universally paired variants are available for O, X, or tandem configurations.
Convincing in everyday life
During operation, constant temperature and vibration levels are observed, ensuring stable dimensional accuracy. Therefore, the pairing can be used in O, X, or tandem configurations to fine-tune preload and stiffness.
Summary
In short: strong axially in one direction, speed-resistant and repeatable – a reliable basis for precise drives.
