Smooth operation under shaft misalignment with Skf

Practical benefits

Automatic compensation for angular misalignment: You accommodate dynamic and static shaft deflection effortlessly thanks to two ball rows in a sphered raceway.
Low friction at high speeds: The reinforced polyamide cage minimizes heat generation and ensures smooth rotation during continuous high-speed runs.
Simple cylindrical bore mounting: You install the bearing easily onto standard 20 mm shafts using the precision cylindrical bore.

In a nutshell

The right choise for

With the Skf 2204 ETN9 double-row self-aligning ball bearing, you keep your machinery running smoothly and reliably, even when faced with shaft deflections or mounting misalignments. Featuring two rows of balls and a common sphered outer ring raceway, it accommodates static and dynamic angular misalignments without increasing friction. The injection-moulded glass-fibre reinforced polyamide cage minimizes friction and heat buildup during high-speed rotation. This open bearing with normal radial internal clearance (CN) mounts directly and precisely onto standard 20 mm shafts via its cylindrical bore. Sized at 20X47X18 mm, it delivers dependable performance for industrial conveyors, fans, and drive systems.
