ZKLN2557-2Z-XL – Axial angular contact ball bearing (double-sided) for compact double-sided axial guidance

Quality that safeguards processes
Under varying axial loads in both directions, this design ensures defined guidance and smooth operation. The consistent running enhances positioning accuracy, and the temperature remains controllable. While limited radial loads can be accommodated, the primary focus remains on axial guidance.

Design and manufacturing quality
The offset raceways with a large contact angle (e.g., 60°) ensure high axial stiffness. Furthermore, precise cage guidance and finely machined raceways keep friction low and running smoothly. Therefore, precise alignment of the components directly impacts running quality, as angular adjustability is limited. The P4S tolerance class further enhances dimensional accuracy and repeatability. Additionally, a polyamide cage guides the balls precisely and stabilizes the running motion. The design with double-sided shields (2Z) also protects the raceway area. This double-acting design distributes axial loads on both sides, eliminating the need for a second bearing point for axial guidance.

Convincing in everyday life
In everyday use, the compact, double-sided guide proves its worth: temperature and vibrations remain predictable, and start/stop cycles are reproducible. This results in predictable quality – even with high cutting data and frequent cycle changes.

Summary
In short: axially strong in both directions, speed-resistant and repeatable – for stable processes in precision drives.
