Wälzlager (auch bekannt als Wälzlager) ähneln Kugellagern insofern, als sie so konstruiert sind, dass sie eine Last tragen und gleichzeitig die Reibung minimieren.

However, roller bearings transmit loads using cylinder rolling elements, rather than balls, to maintain the separation between moving parts of the bearing. They have a wide, flat bearing to provide stability in high-speed applications with high radial loads.

These versatile bearings can contain single or multiple rows of rolling elements; multiple rows can significantly improve radial load capacity. Also, the use of different roller shapes can further reduce friction and support both radial and axial loads.
