Product Description

Four-point contact ball bearings are widely used in various applications, including:
Robotics: Four-point contact ball bearings are commonly used in the joints and arms of robotic systems. They provide high radial and axial load capacity, as well as smooth and precise rotation for the manipulator movements.
Machine tools: Four-point contact ball bearings are often used in precision machine tools, such as milling machines, lathes, and grinding machines. They offer high rigidity, accuracy, and stability, ensuring precise positioning and smooth rotation during machining operations
Cranes and lifting equipment: Four-point contact ball bearings are utilized in the slewing mechanism of cranes and lifting equipment. They can support heavy loads and withstand tilting moments, allowing for efficient and safe lifting and rotation of heavy objects.
Wind turbines: Four-point contact ball bearings are employed in wind turbines to support the main rotor shaft and provide reliable rotation under high loads, gusty winds, and changing operating conditions.
Medical equipment: Four-point contact ball bearings are used in medical devices and equipment, such as CT scanners and surgical robots. They provide smooth and precise motion control, allowing for accurate medical imaging and surgical procedures.
Aerospace and aviation: Four-point contact ball bearings are essential components in aircraft landing gear systems, helicopter rotor heads, and satellite antennas. They offer high load capacity, stiffness, and operational reliability in critical aerospace applications
Automotive industry: Four-point contact ball bearings are utilized in automotive applications such as steering systems, drive shafts, and wheel hubs. They provide excellent resistance to axial and radial forces, ensuring reliable and smooth operation of vehicle components.
