What are the dimensions of this SKF angular contact ball bearing?

It has an inner bore of 40 mm, an outer diameter of 90 mm, and a width of 36.5 mm.

What types of loads can this bearing accommodate?

This double-row bearing accommodates combined radial and axial loads in both directions with a 30° contact angle.

What does the C3 designation mean?

C3 indicates an internal clearance greater than standard, ideal for high speeds or thermal expansion.

What material is the bearing cage made of?

The TN9 cage is made of glass-fibre reinforced polyamide (polymer).

Does this SKF bearing have integrated seals?

No, this is an open bearing without integrated seals and requires external lubrication in the assembly.

Reliable load performance with Skf

Practical benefits

High combined load capacity: The 30° contact angle allows you to effortlessly support heavy radial and axial loads simultaneously.
Smooth and quiet operation: The lightweight polyamide cage minimizes friction so you achieve stable rotation at high operating speeds.
Increased internal clearance: With C3 radial internal clearance, you prevent binding when operating temperatures rise in your machinery.

In a nutshell

The right choise for

Equip your industrial machinery, pumps, or gearboxes with the Skf 3308 ATN9/C3 double-row angular contact ball bearing for dependable performance under heavy loads. Featuring a 30° contact angle, it smoothly supports combined radial and bidirectional axial forces within a compact 40 x 90 x 36.5 mm space. The lightweight glass-fibre reinforced polyamide cage (TN9) reduces friction for quiet, stable operation at high speeds. Additionally, the C3 internal clearance prevents binding as operating temperatures rise, keeping your rotating equipment running efficiently.

Key features according to our expert

Inner diameter: 40 mm
Width: 36,5 mm
Number of rows: 2
Axial clearance: C3
Sealing (bearing): Without seals
Material (bearing seal): Not applicable
Material (cage): Plastic
Outer diameter: 90 mm

Product description

Double row angular contact ball bearings correspond, in their design and operation, to a pair of single row angular contact ball bearings in a back-to-back arrangement, while requiring less axial space. 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
