Machine builders and operators know how easy it is to damage a machining spindle. Tool collision or wrong programming/ settings can often lead to spindle repairs or replacements in a tenth of a second, causing significant downtime and costs. We can now offer a solution with our newly developed aerostatic hybrid bearing technology. In the case of a spindle overload or collision, the shaft does indeed and still touch down on the bearing face, but due to the enormous contact area and a hard-lubricating of the material pair, the shaft, and the bearing faces are not damaged, saving you time and money. Of course, you are going to need a new tool.

We make your spindle more overload-resistant

We are pleased to offer you the opportunity to upgrade your existing front combi bearing with our new aerostatic hybrid bearing system (for ASD-H25/A and ASDH-32/A). Importantly, this upgrade does not require any external changes to your spindle, such as alterations to its size or weight. The following information and the video at the bottom of the page will provide you with a comprehensive understanding of the benefits of this upgrade.

Overload and crash trials

In intensive tests, we deliberately overloaded the bearings and the motor of the same spindle (ASD060H25A) several times, causing tool breakage and even collisions with the workpiece.

The results were beyond our expectations: The spindle bearing remained undamaged. We simply had to replace the tool and could continue working with the same spindle. This demonstrates the robustness and reliability of our new aerostatic hybrid bearing system.

Data from the test trials

The bearing limits could only be tested by letting the tool collide with the workpiece because, in the case of a bearing overload, the drive reported a motor current limit, making it inconclusive whether a touchdown had caused this error.
