1211 K Self-Aligning Ball Bearing 55mm ID x 100mm OD Chrome Steel for Industrial Machinery
The 1211 K self-aligning ball bearing is engineered with chrome steel construction for exceptional durability and strength in demanding industrial applications.
Self-aligning ball bearings feature a double-row design with spherical outer ring raceway that compensates for shaft misalignment, axial deformation, and bearing seat deformation. These bearings allow up to 4 degrees of shaft deflection (1.5 degrees for sealed versions).
