12series Spherical ball bearing


  Self-aligning ball bearings have two rows of steel balls, a shared spherical raceway on the outer ring and two consecutive deep groove raceways on the inner ring. These bearings are capable of withstanding angular misalignments of the shaft relative to the housing, such as those caused, for example, by shaft deflection.

  12series Bearing is versatile and adaptive, ensuring smooth operation even when not perfectly aligned. Its unique design helps prevent stresses on the bearing, resulting in a longer operational life.
