The 1200 series is the industry-standard light series for self-aligning ball bearings. Designed with two rows of balls and a common sphered raceway in the outer ring, these bearings can handle significant angular misalignment between the shaft and housing. Our 1200 series collection includes standard cylindrical bores, tapered bores (K) for adapter sleeve mounting, and sealed versions (2RS) for maintenance-free operation in various precision mechanical environments.
