The FAG 1220-K-M-C3 is a high-quality self-aligning ball bearing manufactured by Schaeffler (FAG/INA). This bearing is engineered to accommodate angular misalignment between the shaft and housing, making it suitable for applications where perfect alignment cannot be maintained. It features a tapered bore (K) for mounting with adapter sleeves, a machined brass cage (M), and C3 radial internal clearance, indicating greater than normal clearance for applications involving high speeds or temperature differences. With an inner diameter of 100 mm, outer diameter of 180 mm, and width of 34 mm, it provides reliable performance in various industrial and agricultural machinery.
