Superior load capacity with Skf

Practical benefits

Higher dynamic load ratings: The double-row layout allows you to support heavy radial and axial forces across your assembly.
Smooth and quiet operation: A lightweight polyamide cage lowers friction so you experience less heat and reduced vibration.
Built for high speeds: The open bearing design enables efficient lubricant flow so you maintain reliable high-speed performance.

In a nutshell

The right choise for

Handle demanding combined radial and axial loads with the Skf 4209 ATN9 double row deep groove ball bearing. Its dual-row design delivers significantly higher load capacity in a compact 45X85X23 mm envelope. The lightweight glass-fibre reinforced polyamide cage (TN9) reduces friction and running noise, ensuring smooth, quiet operation at high rotational speeds. Featuring an open construction, cylindrical bore, and standard radial clearance (CN), this bearing is an ideal choice for 45 mm shafts in electric motors, gearboxes, and industrial pump systems.

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
