FAG 2318-M-C3 is a self-aligning double-row ball bearing from Schaeffler that uses two rows of balls and a spherical outer race to compensate for shaft misalignment in rotating machinery. The "C3" designation denotes larger-than-normal internal clearance, accommodating thermal expansion and mounting tolerances. Designed for radial loads with good misalignment tolerance, it is commonly used in industrial gearboxes, conveyors, pumps, and other equipment where smooth, reliable rotation is needed.
