Smooth operation with the Skf 1203 ETN9

Practical benefits

Self-aligning for shaft deflections: You accommodate angular misalignments and shaft deflections easily thanks to the dual-row spherical raceway design.
Low friction at high speeds: You achieve cooler running temperatures and reduced wear over time due to exceptionally low rolling friction.
Quiet running polymer cage: The lightweight polyamide cage guides the balls smoothly, delivering quiet and dependable continuous rotation.

In a nutshell

The right choise for

Keep your machinery and drive shafts running smoothly with the Skf 1203 ETN9 double-row self-aligning ball bearing. Its dual-row design automatically compensates for shaft deflections and angular misalignments, preventing premature bearing fatigue and unnecessary wear. The lightweight polyamide cage ensures quiet ball guidance and exceptionally low friction at high speeds, keeping operating temperatures low and extending service life. Featuring a 17X40X12 mm profile, a cylindrical bore, and an open design, it gives you full control to apply the precise lubrication required for your application.
