Smooth rotation under misalignment

Practical benefits

Automatic alignment under deflection: The sphered outer ring design lets you accommodate shaft deflections and angular misalignment without extra strain.
Reduced friction in operation: Built with an engineered polyamide cage, you achieve cooler running and quieter operation at high speeds.
Dependable performance with Skf: The double row ball setup distributes radial loads evenly to keep your industrial equipment operating smoothly.

In a nutshell

The right choise for

With the Skf 2203 ETN9, you accommodate shaft deflections and angular misalignments smoothly without generating extra friction or heat buildup. This double row self-aligning ball bearing with a 17 mm cylindrical bore and a 40 mm outer diameter distributes radial forces evenly across two rows of balls. Equipped with an engineered polyamide cage, it ensures quiet operation and low running temperatures, making it ideal for electric motors, fans, conveyor systems, and industrial drive assemblies. The open design with standard cn radial internal clearance prevents premature bearing wear and keeps your rotating equipment running reliably under demanding conditions.

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.
