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

The bearing has a 35 mm bore diameter, an 80 mm outside diameter, and a width of 34.9 mm.

What does the C3 clearance designation mean?

C3 indicates a greater-than-normal internal clearance to accommodate thermal expansion at high speeds and operating temperatures.

What material is the TN9 cage made of?

The TN9 suffix indicates a glass-fibre reinforced polyamide (polymer) cage for smooth, quiet running and reduced weight.

What types of loads can this double-row bearing handle?

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

Does this bearing come sealed?

No, this is an open bearing without built-in seals, allowing you to lubricate it to suit your specific application.

Superior rigidity with Skf 3307 ATN9/C3

Practical benefits

Handles high bidirectional loads: You accommodate severe radial forces and dual-direction axial loads simultaneously thanks to two ball rows with a 30° contact angle.
Compact space-saving setup: You achieve a rigid assembly that requires considerably less axial space than an equivalent pair of single-row bearings.
Smooth high-speed operation: The glass-fiber reinforced polyamide cage paired with C3 clearance minimizes internal friction at speeds up to 8500 rpm.

In a nutshell

The right choise for

With the Skf 3307 ATN9/C3 double-row angular contact ball bearing, you build a rigid and dependable shaft assembly in industrial machinery, pumps, and gearboxes. Featuring two ball rows with a 30° contact angle, it handles high radial forces and bidirectional axial loads simultaneously. The enlarged C3 internal clearance accommodates thermal expansion at high speeds up to 8500 rpm to prevent binding. In addition, the lightweight glass-fibre reinforced polyamide cage reduces running friction and noise. This open 35 x 80 x 34.9 mm bearing requires less axial space than paired single-row bearings and lets you apply the ideal lubricant for your setup.

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
