MRC Bearings was founded in 1901 in Jamestown, New York, as the Marlin Rockwell Corporation. MRC became a premier American manufacturer of precision and industrial bearings, serving aerospace, defense, machine tool, and heavy industry markets. Now part of SKF, the MRC brand endures in legacy installations. MRC used a fully proprietary part numbering system — for example, 205SFF for a sealed 6205 equivalent — making cross-reference essential for replacement sourcing across ISO-standard manufacturers.
