What is Single-row Crossed Roller Bearing?

The Single-row Crossed Roller Bearing is a specialized type of bearing designed with cylindrical rollers alternately arranged and positioned at a 90-degree angle to each other across the raceway. This unique configuration enables it to handle complex loads, including radial, axial, and moment forces, while maintaining high stability and precision. Primarily used in robotics, machine tools, industrial turntables, and precision equipment, Single-row Crossed Roller Bearings offer compactness, high rotating accuracy, and increased rigidity, making them ideal for applications that require both space-saving and high load capacity.
