Robust performance with 3203 A-2ZTN9/MT33

Practical benefits

High combined load capacity: You effortlessly accommodate simultaneous radial and bidirectional axial loads thanks to the double-row layout with a 30° contact angle.
Effective dual shield protection: You keep dust and debris out while retaining grease inside for reliable and long-lasting mechanical operation.
Smooth low-friction rotation: You benefit from reduced friction, quieter operation, and extended service life due to the lightweight polymer cage.

In a nutshell

The right choise for

With the Skf 3203 A-2ZTN9/MT33 double-row angular contact ball bearing, you ensure dependable performance in compact machinery and drive systems. Built with a 30° contact angle, it effortlessly accommodates heavy radial loads and bidirectional axial forces simultaneously. Dual metal shields keep dust and debris out while retaining factory lubrication inside, eliminating the need for periodic relubrication. The lightweight polymer cage ensures smooth, low-friction operation and quiet running. Measuring 17 x 40 x 17.5 mm with standard normal clearance, this bearing is ideal for pumps, compressors, electric motors, and gearboxes.

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): Metal
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
