2220K-C3 Self-aligning ball bearing C3

2220K-C3 The 2220K-C3 is a self-aligning ball bearing with a 100mm tapered bore (1:12 taper) and C3 radial clearance. 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. These bearings are commonly used in applications where shaft deflection or misalignment is expected, such as agricultural equipment, conveyors, woodworking machinery, and textile equipment. The tapered bore design facilitates mounting directly on tapered shafts or adapter sleeves, while the C3 clearance accommodates thermal expansion in applications with elevated operating temperatures.
