Single row four point angular contact bearings have the characteristics of strong bidirectional axial bearing capacity, compact structure, good high-speed performance, anti overturning moment, easy installation, and wide application scenarios. The specific analysis is as follows:
Bi directional axial bearing capacity: Single row four point angular contact bearings are designed to withstand axial loads in two directions simultaneously through the four contact points formed by steel balls and inner and outer raceway. This characteristic makes it stand out in scenarios that require bidirectional axial support, such as machine tool spindles, industrial robot joints, and other equipment. Compact structure: Compared to traditional single row angular contact ball bearings that require paired installation, single row four point angular contact bearings adopt an integrated design, and only a single bearing is needed to achieve bidirectional axial load-bearing function. This structure significantly reduces the axial installation space, making it particularly suitable for precision equipment with strict space requirements.
High speed performance advantages: The precision grinding process of the bearing enables the surface accuracy of the raceway to reach P2/P4 level. With optimized raceway curvature design, the friction coefficient is reduced by 40%, and the maximum speed is increased by more than 30%.
. During high-speed operation, the noise level of the bearings can be controlled below 60dB while maintaining a low-energy consumption operating state.Anti overturning moment capability: The four point contact structure enables the bearing to form a stable four point support between the steel ball and the raceway when subjected to composite loads, effectively resisting overturning moments.
. This characteristic is particularly important in situations where radial force, axial force, and moment need to be simultaneously withstood, such as wind turbine yaw systems, engineering machinery slewing devices, etc.Installation convenience: The split type inner ring design allows the bearing to first fix the outer ring during installation, and then install two half inner rings separately.
. This structure not only simplifies the installation process, but also facilitates later maintenance and replacement. Compared with double row bearings, the installation steps are reduced by 50%, significantly improving assembly efficiency. Widely applicable scenarios: With its high load-bearing capacity, high precision, and high reliability, single row four point angular contact bearings are widely used in high-end equipment fields such as CNC machine tool spindles, industrial robot joints, new energy vehicle drive motors, and aviation engine spindles. In scenarios that require high-precision transmission and heavy-duty support, this type of bearing has become the preferred solution.
