Double Row Angular Contact Ball Bearing 3306 / 5306 OPEN ZZ 2RS Size 30x72x30.2 mm
What is angular contact ball bearing?
Double row angular contact ball bearings correspond, in their design and operation, to a pair of single row angular contact ball bearings in a back-to-back arrangement, while requiring less axial space. They can operate at high speeds and are more suitable than deep groove ball bearings for supporting large axial forces in both directions.A Double Row Angular Contact Ball Bearing is a type of bearing specifically designed to handle two directions of axial loads while also providing high radial load capacity. This unique design features two rows of balls arranged at an angle to the inner and outer raceways, allowing for increased contact points between the balls and the raceways. This results in improved load distribution, higher stiffness, and reduced friction compared to angular contact ball bearing single row. These bearings are commonly used in applications where both radial and axial forces are present, such as automotive wheels, machine tool spindles, and agricultural equipment. With their ability to accommodate heavy loads and high speeds, Double Row Angular Contact Ball Bearings offer superior performance and reliability in demanding environments.
What is the difference between single row and double row angular contact bearing?
While single row bearings accommodate thrust in only one direction, these double row angular contact ball bearings are designed in a way that allows them to accommodate thrust in two directions. Double row angular contact ball bearings are supplied in two designs in order to maintain a non-separable unit.

Benefits of angular contact ball bearings
Contact seals providing excellent protection against the ingress of contamination, reducing wear on the raceways and ball surface, reducing noise, vibration and the risk of lubricant failure
Designed to accomodate radial and axial forces in both directions
Capacity to accept moment loading
Other bearing variants available on request
High-speed capability
Accommodate relatively high radial loads, high axial loads in both directions and tilting moments
Suitable where a stiff bearing arrangement is required
Require less axial space than equivalent pair of single row angular contact ball bearings
3306 bearing dimensions and 5306 bearing dimensions Represent the same bearing. ( A bearing has two names. ) Meaning: skf 5306 means: no cover,open. bearing 5306 ZZ means: double metal seal cover.
