Double row angular contact ball bearings
The design of the double row angular contact ball bearing corresponds to two single row angular contact ball bearings arranged back to back. The bearing is capable of carrying high radial loads and thrust loads in both direction. It is particularly suitable for applications calling for high axial rigidity.
Double Row Angular Contact ball bearings may offer some economic benefits as well as handling and mounting benefits versus pairs of Single Row Angular Contact ball bearings; however, they may offer less design flexibility and performance in some cases.
* Specific geometry of angular contact bearing raceways and shoulders creates ball contact angles that support higher axial loads.
* Expanded options include special lubricants, cage materials, preloads and coatings for additional corrosion resistance.
Double Row Angular Contact ball bearings are available in two numerical series:
?5200 Series – Lighter load, higher speed, more/smaller balls per bore diameter.
?5300 Series – Heavier load, slower speed, fewer/larger balls per bore diameter.

The sealing system of double row angular contact ball bearings prevents the ingress of dirt and ensures an optimal service life.
They parallel, in structure and function, to a pair of single-row angular contact ball bearings with a back to back arrangement.
◪ Contact seals provide an excellent protection against the ingress of contamination, reducing wear, 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:
- Outer and inner ring: diameter, width, threads etc.
- Contour options: crowned, gothic etc.
- Special seals
