Reliable load handling with Skf 3211 ATN9
- Combined bidirectional load support: You reliably accommodate heavy radial forces alongside simultaneous axial thrust in both directions.
- Smooth high-speed operation: The lightweight polyamide cage reduces internal friction so you achieve high rotational speeds seamlessly.
- Stiff and compact arrangement: The double-row layout provides you with superior rigid shaft support while conserving axial mounting space.
With the Skf 3211 ATN9 double-row angular contact ball bearing, you ensure dependable shaft support in demanding equipment such as pumps, compressors, and industrial gearboxes. Featuring a double-row arrangement and a 30° contact angle, it accommodates heavy radial forces and bidirectional axial loads simultaneously. The lightweight glass-fiber reinforced polyamide cage (TN9) minimizes friction and heat generation, allowing smooth high-speed rotation. Measuring 55 x 100 x 33.3 mm with normal axial internal clearance (CN), this open bearing delivers rigid, tilt-resistant operation while saving valuable axial mounting space.
Product description
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.
- 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
