1216-K is a self-aligning ball bearing, 80 mm bore × 140 mm OD × 26 mm wide (3.1496 × 5.5118 × 1.0236 in). It has a tapered bore (1:12).
Self-aligning ball bearings are designed with a spherical outer ring raceway that allows the bearing to accommodate angular misalignment between the shaft and housing. This 1216-K bearing features an 80mm tapered bore (1:12 taper) for secure mounting directly on tapered shafts or with adapter sleeves, eliminating the need for additional locking devices.
