1218K Self-aligning ball bearing

1218K Self-aligning ball bearings feature two rows of balls running on a spherical outer ring raceway, allowing the bearing to accommodate angular misalignment between the shaft and housing. This 1218K bearing has a 90mm tapered bore (1:12 taper) for direct mounting onto tapered shafts or adapter sleeves, providing secure positioning and simplified installation. These bearings are commonly used in applications where shaft deflection or mounting errors are expected, including agricultural equipment, conveyor systems, wood processing machinery, and general industrial equipment where alignment cannot be precisely maintained during operation.
