Reliable load performance with Skf

Practical benefits

Simultaneous combined load support: You manage heavy radial forces and bidirectional axial loads effortlessly thanks to the double-row layout with a 30° contact angle.
Dual rubber contact seals: Seals on both sides keep dirt and moisture out while retaining lubricant to ensure an extended working life.
Smooth and low friction: The reinforced polymer cage minimizes friction and noise, delivering quiet, reliable rotation even at high operating speeds.

In a nutshell

The right choise for

With the Skf 3203 A-2RS1TN9/MT33 double-row angular contact ball bearing, you handle heavy radial forces and bidirectional axial loads simultaneously in a compact footprint. Designed with a 30° contact angle and a double-row layout, this bearing delivers high stiffness and running accuracy, making it ideal for pumps, gearboxes, and electric motors. Integrated 2RS1 rubber contact seals on both sides keep dirt and moisture out while preventing lubricant leakage. Combined with a low-friction glass-fibre reinforced polyamide cage and factory grease lubrication, you get a dependable, low-maintenance, and quiet bearing solution ready for demanding industrial service.

Key features according to our expert

Inner diameter: 17 mm
Width: 17,5 mm
Number of rows: 2
Axial clearance: CN (Normal)
Sealing (bearing): Sealed on both sides
Material (bearing seal): Rubber
Material (cage): Plastic
Outer diameter: 40 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
