Description
The 3305 ATN9 is a high-performance double row angular contact ball bearing designed to operate under demanding conditions. Functionally equivalent to a matched pair of single row angular contact bearings in a back-to-back (O) arrangement, it provides superior rigidity and stability. This design enables the bearing to support high radial loads, heavy axial loads in both directions, and resist tilting moments, making it highly versatile.
With a 30° contact angle and compact construction, the 3305 ATN9 saves axial space without compromising performance—ideal for applications where installation space is limited. Its non-metallic cage ensures low friction, reduced noise, and stable high-speed operation, while its precision-engineered bearing steel construction provides durability under challenging conditions.
As part of the SKF Explorer performance class, the 3305 ATN9 offers enhanced load ratings, improved efficiency, extended service life, and consistent reliability in demanding applications such as gearboxes, pumps, compressors, and other precision machinery.
