What loads can this bearing accommodate?

This double-row bearing handles radial loads and axial loads in both directions simultaneously.

What does the C3 designation indicate?

C3 indicates greater internal clearance than normal, suitable for higher speeds or thermal expansion.

What are the exact dimensions of the SKF 3309 A/C3?

The bearing has a 45 mm bore diameter, 100 mm outer diameter, and 39.7 mm width.

Is this SKF bearing sealed?

No, this is an open bearing without built-in seals and requires external lubrication.

What is the contact angle of this bearing?

This angular contact ball bearing features a 30° contact angle.

High load stability with Skf

Practical benefits

Bidirectional axial load support: You efficiently accommodate high radial forces and simultaneous axial loads in both directions.
Compact and rigid design: The double-row layout provides a stiff bearing arrangement while taking up less axial space.
Enhanced C3 internal clearance: You reliably accommodate thermal expansion and maintain smooth rotation during high-speed industrial operations.

In a nutshell

The right choise for

With the Skf 3309 A/C3 double-row angular contact ball bearing, you establish a rigid and dependable bearing arrangement for demanding industrial equipment. Its two-row design with a 30° contact angle accommodates heavy radial forces and bidirectional axial loads simultaneously while requiring less axial mounting space. Featuring dimensions of 45 x 100 x 39.7 mm, an open configuration, and a sheet brass cage, it offers increased C3 internal clearance. This allows you to compensate for thermal expansion during high-speed operation in gearboxes, pumps, and compressors.

Number of rows: 2
Axial clearance: C3
Sealing (bearing): Without seals
Material (bearing seal): Not applicable
Material (cage): Brass (sheet)
Outer diameter: 100 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
