FC3248168 refers to a Four-Row Cylindrical Roller Bearing primarily for rolling mill applications, with dimensions: 160mm bore (d), 240mm outer diameter (D), and 168mm width (B), featuring high radial loads, often cross-referenced with SKF, FAG, NSK, NTN, and Koyo, and available from various manufacturers, not just SKF/FAG, though they produce similar types. 

Where to Find Stock:
You won't find this specific code on a standard SKF or FAG general catalog directly as a primary part number but as an equivalent for a generic or Chinese standard (FC series). 

To get an official SKF or FAG equivalent: You'd need to provide the dimensions (160x240x168mm) and application (rolling mill) to an authorized distributor for their specific part number, as the FC3248168 is a common industry designation.
