Smooth rotation with automatic alignment

Practical benefits

Automatic compensation of misalignments: You accommodate shaft deflections and angular errors effortlessly with two rows of balls on a spherical raceway.
Low friction high speed: The specialized Skf design reduces operational heat, allowing you to run rotating equipment smoothly at high speeds.
Quiet running polymer cage: The durable polyamide cage spaces the rolling elements evenly, reducing vibration and noise during intensive operation.

In a nutshell

The right choise for

With the Skf 1209 ETN9 self-aligning ball bearing, you keep machinery running smoothly and reliably, even when facing shaft deflection or misalignment. Thanks to two rows of balls running on a spherical outer raceway, this open bearing accommodates angular errors automatically. The glass-fibre reinforced polyamide cage ensures low-friction operation, keeping your equipment cooler at high speeds while minimizing vibrations and noise. Featuring a 45 mm cylindrical bore, an 85 mm outside diameter, and a 19 mm width, it mounts directly onto straight shafts in industrial drivetrains, blowers, and conveyor systems.
