ZKLFA0640-2RS – Axial angular contact ball bearing (double-sided) for high stiffness under alternating axial loads

Quality that safeguards processes
The double-sided design transmits axial forces in both directions while remaining rigid and speed-resistant. At the same time, the smooth running enhances positioning accuracy and keeps the temperature controllable. This allows for the integration of limited radial loads, but the primary function remains axial guidance.

Design and manufacturing quality
The offset raceways with a large contact angle (e.g., 60°) ensure high axial stiffness. 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 minimal. At the same time, the P4S tolerance class supports dimensional accuracy and repeatability. A polyamide cage guides the balls precisely and stabilizes the running motion. Furthermore, a 2RS seal protects the raceway area and retains the lubricant within the system. 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.
