Double Row Angular Contact Ball Bearing 3306M 3307 3308 , auto bearing
What are the structural classifications of double row angular contact ball bearings?
The design of double row angular contact ball bearings is basically the same as that of single row angular contact ball bearings, but it only takes up less axial space. Double-row angular contact ball bearings can withstand radial loads and axial loads acting in both directions. It can limit the axial displacement of the shaft or housing in both directions. The contact angle is 30 degrees. Can provide higher rigid bearing arrangements and can withstand overturning moments. Double-row angular contact ball bearings can withstand large radial and axial combined radial and axial loads and moment loads, limiting axial displacement on both sides of the shaft. It is mainly used in parts that limit axial displacement of the shaft and the housing in both directions.
Double-row angular contact ball bearing structure classification:
1. Standard design for A-type bearings with an outer diameter less than or equal to 90mm. No ball gap, so it can withstand equal axial load in both directions. The use of lightweight glass fiber reinforced nylon 66 cage, bearing temperature rise is very small.
2. The standard design of B-type bearings with an outer diameter greater than 90mm. There is a ball gap on one side, and it is equipped with a steel stamped cage or a brass solid cage.
3. Type C is a reinforced structure with a ball gap on one side, which can hold more steel balls, so the bearing capacity is higher.
4.Dual-row angular contact ball bearings with dust cover on both sides and seals on both sides, A type design and C type design, can be equipped with dust cover (non-contact type) or seal ring (contact type) on both sides . Sealed bearings are filled with rust-proof lithium-based grease, and the operating temperature is generally -30 to + 110 ° C. No relubrication is required during use, and it should not be heated or cleaned before installation.

What are the similarities and differences between the double row angular contact ball bearings and the single row in close contact?
Double-row angular contact ball bearings are designed to adjust the internal clearance, so they can be used normally; single-row pairs are installed close to each other, and if they are fitted right at the factory, they can also be installed normally. It is bought separately for pairing and close use. Generally speaking, it is difficult to adjust the matching clearance, which may affect normal use or service life!
