Smooth rotation with Skf 1208 ETN9

Practical benefits

Automatic compensation for misalignment: The double-row ball design accommodates shaft deflections effortlessly so you prevent unwanted stress on critical components.
Quiet lightweight polyamide cage: The durable polymer cage reduces operational noise and minimizes friction heat during high-speed continuous running.
Low operational running friction: You achieve efficient performance and reduce wear across your machinery thanks to the optimized spherical outer ring geometry.

In a nutshell

The right choise for

Keep your rotating machinery running smoothly and reliably with the Skf 1208 ETN9 double-row self-aligning ball bearing. Featuring two rows of balls and a sphered raceway, it automatically accommodates shaft deflections and angular misalignment without increasing friction or generating excess heat. The lightweight glass-fibre reinforced polyamide cage (TN9) ensures quiet operation during continuous high-speed runs and minimizes wear across critical components. Designed with a 40 mm cylindrical bore, an 80 mm outside diameter, and an 18 mm width, this open bearing is the ideal solution for conveyor rollers, gearboxes, and industrial drive systems.

Product description

Self-aligning ball bearings have two rows of balls, a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring. They are insensitive to angular misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection.
