READ MORE1. Technical features of double-row angular contact ball bearings
Double-row angular contact ball bearings are a special type of rolling bearings. Their structural features are that the inner and outer rings are both spherical, and the steel balls are arranged in two rows, with the cage maintaining their appropriate spacing. This design allows the double-row angular contact ball bearing to effectively withstand axial loads in both directions while bearing radial loads, thus having higher rigidity and load-bearing capacity. Its contact angle is usually 30 degrees, which enables the bearing to automatically adjust the axis misalignment caused by the deflection or non-concentricity of the shaft or housing during operation, maintain the normal rotation of the bearing, and reduce friction and energy loss.
The technical features of double-row angular contact ball bearings include:
Strong load-bearing capacity: Due to the layout of the double-row balls, the bearing can simultaneously withstand large radial and axial combined loads, meeting the use requirements under high-load conditions.
High rigidity: The compact structural design enables the bearing to maintain good stability under high-speed rotation and high-precision working conditions.
Self-balancing: The automatic self-aligning performance of the bearing enables it to automatically adjust the axis misalignment caused by the deflection or non-concentricity of the shaft or housing, reducing wear and vibration.
Wide range of applications: widely used in mechanical systems such as machine tool spindles, metallurgical equipment, excavators, high-speed offset printing machines, etc. that need to bear radial and axial loads at the same time.
