Description
The 3311 A/C3 Double Row Angular Contact Ball Bearing is designed to accommodate radial and axial loads in both directions while offering high-speed capability and robust load-carrying capacity. This bearing is ideal for applications requiring stiff bearing arrangements and is particularly beneficial for high axial loads and tilting moments.
Unlike a pair of single-row angular contact ball bearings, the double-row design of the 3311 A/C3 allows for a more compact solution with reduced axial space. With a basic dynamic load rating of 112 kN and a basic static load rating of 81.5 kN, this bearing ensures reliable performance under demanding conditions. The C3 radial internal clearance and SKF Explorer performance class offer added reliability and longevity.
While the bearing is non-sealed and unlubricated, it can be tailored to your specific lubrication needs. With a contact angle of 30° and a limiting speed of 5,300 r/min, it operates effectively in high-speed applications.
