High load capacity in compact assemblies

Practical benefits

Reliable double row design: With the Skf two-row design, you easily support high combined radial and bidirectional axial forces.
Sealed against dirt ingress: The contact rubber seals on both sides protect against dust and contaminants to maximize service life.
Rigid and space saving: You achieve an exceptionally stiff arrangement in tight spaces thanks to the 30° contact angle.

In a nutshell

The right choise for

With the Skf 3204 A-2RS1TN9/MT33 angular contact ball bearing, you gain exceptional stability and reliability for demanding industrial applications. Its double-row design with a 30° contact angle accommodates heavy combined radial loads and bidirectional axial forces with ease. Measuring 20 x 47 x 20.6 mm, this compact bearing requires less axial space than two single-row bearings. The built-in 2RS1 contact rubber seals on both sides reliably protect against dust, dirt, and moisture. Pre-lubricated with factory-applied MT33 grease, it eliminates the need for periodic relubrication, keeping your pumps, gearboxes, and drive shafts running smoothly and maintenance-free.

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
