Cross cylindrical bearings, with both the inner and outer rings being integral structures, have minimal impact on performance during installation, ensuring stable rotational accuracy and torque. They are suitable for applications involving the rotation of inner and outer rings. Despite the minimal size reduction of the inner and outer rings, cross cylindrical bearings maintain high rigidity, making them ideal for industrial robot joints or rotating parts, rotary tables in machining centers, robotic arm rotation sections, precision rotary tables, medical equipment, measuring instruments, manufacturing devices, and similar applications.
