Four Point Contact Ball Bearings

Four-point contact ball bearings are a type of radial ball bearing that are designed to support axial loads in both directions, as well as radial loads. They are commonly used in applications where high load-carrying capacity, high stiffness, and low friction torque are required.

Unlike other types of ball bearings, which have a raceway on both the inner and outer rings, four-point contact ball bearings have two raceways on the outer ring and one on the inner ring. This unique design allows the bearing to support both radial and axial loads, as well as tilting moments, making them suitable for applications with complex loads.

Four-point contact ball bearings are commonly used in applications such as construction equipment, robotics, and medical equipment, where high precision and reliability are essential. They are also used in turntables, indexing tables, and other applications where high stiffness and low friction torque are required.

Overall, four-point contact ball bearings offer a combination of high load-carrying capacity, low friction torque, and excellent performance under complex loads, making them a versatile and reliable choice for a wide range of applications.
