1209 ETN9 Self-Aligning Ball Bearing – Compact & Durable

Self-aligning ball bearing
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.

    Accommodate static and dynamic misalignment
    Excellent high-speed performance
    Excellent light load performance
    Low friction

Knowledge and introduction of bearings

The 1209 ETN9 Self-Aligning Ball Bearing is a high-quality bearing designed for applications that require reliable performance even in the presence of misalignment. This bearing is ideal for machinery and equipment subjected to both radial and axial loads, while its self-aligning feature ensures smooth operation even when misalignment occurs between the shaft and housing. With its robust construction and self-aligning capabilities, the 1209 ETN9 extends the service life of your equipment and reduces maintenance costs, making it an essential component in many industrial applications.

The 1209 ETN9 features a spherical outer raceway, allowing the bearing to automatically align itself in the case of slight shaft misalignment. This reduces unnecessary wear and tear on the bearing, increasing its durability and preventing premature failure. The bearing is constructed from high-quality chrome steel (AISI 52100), known for its excellent wear resistance and strength. With its low-friction design, the 1209 ETN9 operates efficiently even at higher speeds, ensuring smooth, reliable performance.

This bearing can be used in a wide range of applications, including electric motors, agricultural machinery, conveyors, and other heavy-duty equipment. Its ability to handle misalignment and high radial loads makes it ideal for applications in industries where alignment issues are inevitable or where heavy operational loads are common.
