The INA-FAG 1209 is a genuine self-aligning ball bearing, part of the Schaeffler Group, featuring two rows of balls and a common concave spherical raceway in the outer ring. This design allows for angular misalignment of the shaft relative to the housing, making it highly suitable for applications where alignment errors or shaft deflections can occur. With an inner diameter of 45mm, an outer diameter of 85mm, and a width of 19mm, this robust bearing ensures reliable performance and extended service life in various industrial machinery.
