Reliable load handling with Skf 3211 ATN9

Practical benefits

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.

In a nutshell

The right choise for

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.

Key features according to our expert

Inner diameter: 55 mm
Width: 33,3 mm
Number of rows: 2
Axial clearance: CN (Normal)
Sealing (bearing): Without seals
Material (bearing seal): Not applicable
Material (cage): Plastic
Outer diameter: 100 mm

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
