Firstly, the perceived product quality is what makes a high-quality plain bearing. It quickly becomes apparent whether all embossing is cleanly machined, no stamped edge marks or frayed edges are visible, and the materials and colors are right at first glance. In addition, all dimensions and measurements of a high-quality plain bearing are correct - regardless of the (very high) quantity. In-house and supplier test protocols ensure flawless product quality. Ultimately, the delivery of a high-quality plain bearing always includes appropriate written documentation, e.g. in the event of complaints.
