Single row four point angular contact bearings have the advantages of compact structure, high load-bearing capacity, high rigidity, high speed performance, convenient installation and maintenance, and adaptability to high temperatures and special working conditions. The following is a specific analysis:
Compact structure and space saving: A single row four point angular contact bearing can be regarded as a two in one combination of two single row angular contact ball bearings. Compared with double row angular contact ball bearings, it occupies less axial space, which is conducive to the compact design of the equipment and suitable for occasions with strict installation space requirements.
High load-bearing capacity: The four point contact design enables the bearing to withstand larger radial and axial loads, with a more uniform load distribution, improving the overall load-bearing capacity of the bearing. The inner and outer raceway designs have peach shaped cross-sections, which help support axial loads acting in two directions. The contact angle is 35 °, and the axial load capacity is large, suitable for bearing pure axial loads or composite loads with large axial loads.
High rigidity: The optimized internal structure gives the bearing high rigidity, which can maintain low deformation under high loads and ensure stable operation of the equipment.
High speed performance: Bearings allow for very high speeds, smooth operation, and are suitable for high-speed operation. This is due to its optimized internal structure, high-quality cage materials (such as solid brass or PEEK), and outer ring guided cage design.
Long lifespan and low noise: Due to uniform load distribution and minimal wear, bearings have a relatively long service life, reducing maintenance costs and replacement frequency. At the same time, the low noise generated during operation helps to improve the overall operating quality of the equipment and the comfort of the working environment.
Easy to install and maintain: The inner (or outer) ring of the bearing is precisely assembled from two half rings, making it easy to install and disassemble, as well as maintain and replace. In addition, to prevent the outer ring from rotating, most bearings are equipped with an outer ring with two positioning grooves, which can be fixed to the bearing seat with positioning pins.
Adapt to high temperatures and special working conditions: Four point contact ball bearings that have undergone special heat treatment and are equipped with brass or PEEK retainers can operate at high temperatures of 150 degrees, while products with S1 suffix can operate at high temperatures of 200 degrees. Some large four point contact ball bearings have two positioning slots on the outer ring for fixing the outer ring. Bearings with an outer diameter greater than 240mm can meet the high temperature requirement of 200 degrees.
