The Schaeffler 1211K.TV.C3 is a two-row self-aligning ball bearing with a 55 mm bore, 100 mm outer diameter, and 21 mm width, engineered to accommodate shaft and housing misalignment and mounting tolerances. It uses radial internal clearance class C3, offering extra clearance for thermal growth and deflection under load. With a compact 55×100×21 mm footprint and a robust two-row design, it suits gearboxes, conveyors, and other machinery where precise alignment cannot be guaranteed. Sold under the FAG/INA lineage within Schaeffler, this bearing provides a standard, interchangeable option for compatible housings and shafts.
