The Precision Parts 203FF is a sealed, single-row deep groove ball bearing engineered for use in alternators, generators, power steering pumps, and steering gear housings. Dimensioned at 17mm bore x 40mm outer diameter x 12mm width (equivalent to a 6203-2RS metric bearing), this bearing is a direct-fit replacement for a wide range of domestic and import vehicles.
