[tab name='More Information']
SKF double row angular contact ball bearings are precision-engineered components designed to accommodate both radial and axial loads simultaneously. They belong to the family of angular contact ball bearings and are known for their high load-carrying capacity and excellent rotational performance.
These bearings consist of two rows of balls, which are positioned at an angle to the bearing axis. This configuration allows the bearings to support axial loads in both directions, as well as radial loads, making them suitable for applications where combined loads and high speeds are present.
The inner and outer rings of SKF double row angular contact ball bearings are designed to provide optimized raceway profiles, resulting in reduced friction and enhanced durability. This design feature ensures smooth and efficient operation, even under demanding conditions.
SKF double row angular contact ball bearings are available in various designs, including the open type, sealed, or shielded options. The sealed and shielded versions offer additional protection against contamination and retain lubrication within the bearing, prolonging its service life.
These bearings are manufactured using high-quality materials and undergo rigorous quality control processes to ensure consistent performance and reliability. They are commonly used in a wide range of industries, including machine tooling, pumps, compressors, gearboxes, and electric motors.
SKF, a leading global manufacturer of bearings, is known for its commitment to innovation and technological advancements. Their double row angular contact ball bearings are designed to meet the highest standards of quality, precision, and efficiency, making them a preferred choice for demanding applications where reliability and performance are paramount.
