Plastic star buttons with anti-friction bearing - Handles and buttons

With the star knobs featuring an integrated anti-friction bearing, the clamping force can be doubled compared to standard star knobs. Therefore, this product can also be used by individuals with limited hand strength (e.g., during rehabilitation) to achieve comparable clamping forces with less effort. Less hand strength is also required to loosen tightly secured star knobs. The increase in clamping force is achieved through the integrated axial needle bearing, which generates very low surface friction on the fixed support surface during tightening. The hardened support washers are designed for high clamping forces, and the bearing ensures a long service life due to its significant load capacity. The large fixed support surface helps to sustainably preserve the clamped component. A washer is therefore no longer necessary. Thanks to the modular structure.
