Double row angular contact ball bearings are typically used in applications requiring high radial and axial loads, such as machine tools, pumps, and gearboxes. They are also common in applications needing high speeds and precision, such as aerospace and automotive industries. The contact angle between the balls and the raceways is usually 30 degrees, although bearings with 15 degrees or 40 degrees are also available. One of the advantages of double row angular contact ball bearings is their ability to accommodate misalignment. The two rows of balls enable the bearing to compensate for small angular misalignments between the shaft and the housing, thereby extending the bearing's service life. AUBEARING manufactures ISO standard metric-sized chrome steel (52100) double row angular contact bearings with inner diameters ranging from 190 mm to 280 mm. They are manufactured to ABEC 1 standards and are available with industrial grade 2RS double seals or ZZ double shields.
Double row angular contact bearings consist of two back-to-back arranged single row bearings. They occupy less axial space and can withstand radial loads as well as axial loads in both directions. The axial load carrying capacity depends on the contact angle. The larger the angle, the greater the axial load the bearing can withstand. Double row bearings are angular contact bearings designed to meet the need for increased axial and radial loads in applications where space is limited. These bearings are used in agricultural machinery, pumps, packaging equipment, conveying equipment, compressors, and elevators.
Longer service life: Smooth design of the raceways and shoulder angles reduces wear.
Design efficiency: Bearings feature improved raceways that significantly reduce edge stresses, ensuring long-term reliability and safety.
Reduced lubricant consumption: The design dynamics of the bearings help maintain smooth and faster rotation over longer periods without the need for lubricant intervention.
Quiet operation: Smooth dynamics of shoulders and raceways minimize friction, vibration, and noise.
Less heat generation: Designed with wear-resistant materials, optimal hardness, and dimensional stability capable of withstanding temperatures up to 150°C.
