What is precision four-point contact ball slewing bearing

Precision four-point contact ball slewing bearing is a kind of bearing product widely used in the field of mechanical transmission.It has the characteristics of high precision, high load capacity, and long service life, and is widely used in machine tools, metallurgy, printing, textile and other industries.

The structure of a precision four-point contact ball slewing support bearing consists mainly of an inner ring, an outer ring, steel balls, and a cage.The inner and outer rings are the main parts of the bearing, usually made of high-carbon chromium bearing steel, which has high hardness and wear resistance after precision machining and heat treatment.The steel balls are the rolling elements of the bearing, usually made of high-quality chromium steel, with a hardened surface to provide high hardness and long life.The role of the cage is to guide the rolling of the steel balls and maintain their position stability.

Characteristics of precision four-point contact ball slewing bearing

High precision: The inner and outer rings and steel balls of the precision four-point contact ball slewing bearing have been subjected to precision machining and heat treatment, resulting in high geometric and dimensional accuracy, ensuring the stability and precision of the bearing during operation.

High load capacity: The precision four-point contact ball slewing bearing adopts a four-point contact design, which can withstand greater radial and axial loads and has higher load capacity.

Long life: The inner and outer rings and steel ball surfaces of the precision four-point contact ball slewing bearing have undergone hardening treatment, providing high hardness and long life, ensuring the stability and durability of the bearing during long-term operation.

Low friction coefficient: The precision four-point contact ball slewing bearing has a low friction coefficient, which can reduce the frictional resistance of the bearing during operation, reducing energy consumption and temperature.

Wide range of applications: Precision four-point contact ball slewing bearings can adapt to different working environments and operating conditions, and are widely used in machine tools, metallurgy, printing, textile and other industries.

In short, the precision four-point contact ball slewing bearing is a high-precision, high-capacity, long-life bearing product that is widely used in the field of mechanical transmission.It features low friction coefficient, high precision, and high load capacity, which can ensure the stability and accuracy of the mechanical transmission system, improve work efficiency, and reduce maintenance costs.

Application areas of precision four-point contact ball slewing bearing

Precision four-point contact ball slewing bearing is a type of bearing component widely used in the field of mechanical transmission.Its structural feature is that four steel balls are installed between the inner and outer rings, which form four contact points between the inner and outer rings, hence the name "four-point contact ball slewing bearing".This type of bearing has high load capacity, long service life and low friction coefficient, so it is widely used in many high-precision and high-load mechanical transmission systems.
