What types of loads can this angular contact ball bearing accommodate?

It supports high radial loads and axial forces in both directions thanks to its double-row design and 30° contact angle.

What are the exact dimensions of this SKF bearing?

The bore diameter is 40 mm, outer diameter is 90 mm, and total width is 36.5 mm.

What type of sealing does the 3308 A-2RS1TN9/MT33 bearing have?

It features 2RS1 rubber contact seals on both sides to protect against dirt and moisture.

Does this bearing need lubrication before installation?

No, it comes pre-greased with MT33 grease and is ready for immediate mounting.

What material is used for the bearing cage?

It features a TN9 cage made of glass-fibre reinforced polyamide (plastic).

Robust Skf bearing for combined loads

Practical benefits

High combined load capacity: The double-row layout with a 30° contact angle easily accommodates high radial forces and axial loads in both directions.
Double-sided sealing protection: With rubber contact seals on both sides, you keep lubrication inside while shielding the bearing from dirt and moisture.
Smooth low-friction operation: The engineered polymer cage reduces internal friction, ensuring you achieve quiet running and long service life during operation.

In a nutshell

The right choise for

With the Skf 3308 A-2RS1TN9/MT33 double-row angular contact ball bearing, you easily handle heavy radial loads and bidirectional axial forces simultaneously. Designed with a 30° contact angle, it provides rigid shaft guidance in rotating machinery such as industrial pumps, compressors, and gearboxes. The dual 2RS1 rubber contact seals keep contaminants and moisture out while retaining the factory-filled MT33 grease, making the bearing maintenance-free and ready for instant installation. In addition, the durable TN9 polymer cage reduces internal friction and vibrations, ensuring smooth, quiet operation and an extended service life for your equipment.

Key features according to our expert

Inner diameter: 40 mm
Width: 36,5 mm
Number of rows: 2
Axial clearance: CN (Normal)
Sealing (bearing): Sealed on both sides
Material (bearing seal): Rubber
Material (cage): Plastic
Outer diameter: 90 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
