High load stability with Skf

Practical benefits

Reliable dual contact sealing: Built-in rubber seals prevent contaminant ingress and retain lubricant efficiently, so you achieve a significantly longer service life.
Combined load capacity: With a 30° contact angle, you can easily support high radial forces alongside bidirectional axial loads simultaneously.
Compact and rigid design: The durable polymer cage delivers smooth rotation and high arrangement stiffness while occupying less axial space in your assembly.

In a nutshell

The right choise for

With the Skf 3306 A-2RS1TN9/MT33 double-row angular contact ball bearing, you ensure dependable power transmission and high arrangement rigidity in compact installations. Featuring a 30° contact angle, it simultaneously supports high radial forces and bidirectional axial loads, making it an excellent solution for drive shafts, gearboxes, pumps, and compressors. The built-in dual rubber contact seals (2RS1) effectively prevent dust, dirt, and moisture ingress while retaining lubricant, delivering a maintenance-free design with no need for periodic relubrication. Additionally, the durable glass-fibre reinforced polymer cage ensures smooth, quiet rotation across its 30 x 72 x 30.2 mm envelope.

Product description

Double row angular contact ball bearings, with seals or shields, correspond to a pair of single row angular contact ball bearings in a back-to-back arrangement, while requiring less axial space. Depending on the sealing execution, 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
Integral sealing prolongs bearing service life
