Industrial robots use crossed roller bearings because they offer several key advantages crucial to robotic performance. These bearings are designed to handle high radial, axial, and moment loads simultaneously, making them ideal for the demanding conditions of robotic joints and axes. Their compact size and low profile allow for space-efficient designs without compromising on load capacity. Crossed roller bearings also provide high rigidity, precision, and minimal deflection, ensuring smooth and accurate movement in robots. Furthermore, they are durable, offer long service life, and operate with low friction, all of which contribute to enhanced robot performance and reduced maintenance. These features make crossed roller bearings a preferred choice for industrial robots in various applications, including manufacturing, assembly, and precision tasks.
