The SKF 1204 is a genuine self-aligning ball bearing featuring two rows of balls and a common sphered raceway in the outer ring. This design makes the bearing inherently self-aligning and insensitive to angular misalignment of the shaft relative to the housing. It is particularly well-suited for applications where significant shaft deflections or mounting errors are anticipated. With an inner diameter of 20 mm, an outer diameter of 47 mm, and a width of 14 mm, this bearing provides reliable performance in demanding conditions. Its robust construction ensures durability and consistent operation.
