What are the dimensions of this angular contact ball bearing?

The bearing has a 25 mm inside diameter, a 62 mm outside diameter, and a width of 25.4 mm.

What types of loads can this bearing accommodate?

With a 30° contact angle and two ball rows, it supports combined radial and axial loads in both directions.

What does the C3 designation indicate?

C3 designates greater internal axial clearance than normal (CN), ideal for higher operating temperatures or speeds.

What does the TN9 code signify?

The TN9 suffix indicates that the ball cage is made from glass-fibre reinforced polyamide (polymer).

Does this SKF bearing have integrated seals?

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

High load capacity by Skf

Practical benefits

Accommodates heavy combined loads: You reliably support simultaneous radial forces and double-direction axial loads in demanding drive systems.
Space saving compact design: The double-row construction requires less axial space than an equivalent pair of single-row bearings.
Smooth high speed operation: With C3 internal radial clearance and a lightweight polymer cage, you maintain efficiency at high speeds.

In a nutshell

The right choise for

With the Skf 3305 ATN9/C3 double-row angular contact ball bearing, you reliably handle heavy radial forces and bidirectional axial loads simultaneously. Featuring a 30° contact angle and compact dimensions of 25 x 62 x 25.4 mm, it matches the capability of two single-row bearings while saving valuable axial space in gearboxes and pumps. The C3 internal clearance accommodates thermal shaft expansion at elevated operating temperatures and high speeds. Combined with a lightweight glass-fibre reinforced polyamide cage, you reduce friction, noise, and cage inertia for smooth, rigid shaft guidance.

Key features according to our expert

Inner diameter: 25 mm
Width: 25,4 mm
Number of rows: 2
Axial clearance: C3
Sealing (bearing): Without seals
Material (bearing seal): Not applicable
Material (cage): Plastic
Outer diameter: 62 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
