What are the dimensions of this SKF ball bearing?

The bearing has a 35 mm bore (inside diameter), an 80 mm outside diameter, and a 31 mm width.

What is the advantage of a double-row deep groove ball bearing?

With two rows of balls, it delivers significantly higher load-carrying capacity than an equivalent single-row bearing.

Does the SKF 4307 ATN9 come sealed?

No, this bearing is an open type without seals or shields.

What material is used for the cage?

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

What radial clearance does this bearing have?

It features standard normal radial internal clearance (CN).

Durable performance for heavy loads

Practical benefits

High dual directional capacity: Two rows of balls allow this bearing to accommodate heavy radial and axial loads simultaneously.
Smooth high speed operation: The lightweight polyamide cage from Skf reduces friction and vibration during demanding high-speed rotations.
Simple straight bore mounting: The standard 35 mm cylindrical bore lets you fit the open bearing directly onto your shaft.

In a nutshell

The right choise for

With the Skf 4307 ATN9 double-row deep groove ball bearing, you give your machinery and drive shafts superior load capacity and stability. Thanks to its two rows of balls, this bearing simultaneously accommodates heavy radial and axial loads in both directions, making it ideal for demanding gearboxes, pumps, and electric motors. The lightweight glass-fibre reinforced polyamide cage (TN9) minimizes friction and vibration to ensure smooth, quiet operation at high speeds. Featuring a standard 35 mm cylindrical bore, an 80 mm outside diameter, and a 31 mm width, this open steel bearing mounts accurately onto your shaft in lubricated enclosures.

Product description

Double row deep groove ball bearings correspond, in their design and operation, to a pair of single row deep groove ball bearings. They are robust in operation, requiring little maintenance, can operate at high speeds and accommodate radial and axial loads in both directions. They are slightly wider than single row bearings of the same bore and outside diameter but have a considerably higher load carrying capacity.

Versatile and robust design
High-speed capability
Accommodate high axial and radial loads in both directions
Require little maintenance
