Reliable rotational performance with Skf

Practical benefits

Superior dual contact seal protection: Integrated rubber seals on both sides protect the internal components against dust and moisture, ensuring you achieve a longer service life.
Handles heavy bidirectional combined loads: The double-row layout with a 30° contact angle allows you to support high radial forces and axial loads in both directions.
Smooth running at high speeds: With built-in C3 internal clearance, you maintain smooth, low-friction operation even under elevated operating temperatures and high rotational speeds.

In a nutshell

The right choise for

With the Skf 3305 A-2RS1TN9/C3MT33 double-row angular contact ball bearing, you ensure dependable rotational performance in compact shaft assemblies and drives. Designed with a 30° contact angle, it accommodates heavy radial loads, bidirectional axial thrust, and tilting moments simultaneously. Built-in rubber contact seals on both sides keep dust, debris, and moisture out of the internal raceways, extending service life without maintenance needs. The C3 internal radial clearance prevents binding under elevated temperatures and high operational speeds, ensuring smooth, low-friction running. It delivers a rigid, durable bearing arrangement ideal for industrial pumps, compressors, and electric motor drives.

Key features according to our expert

Inner diameter: 25 mm
Width: 25,4 mm
Number of rows: 2
Axial clearance: C3
Sealing (bearing): Sealed on both sides
Material (bearing seal): Rubber
Material (cage): Brass (sheet)
Outer diameter: 62 mm

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
