Answer-RC 12*18*4 "SP" Bearings 10pk. ANSBR1218 Answer-RC 12*18*4 "SP" Bearings 10pk Rubber Seal / Metal Shield. Excellent quality and superb value. These Answer-RC bearings use 1 x rubber seal and 1 x metal shield. This is to be installed with the rubber seal facing the dirt. The metal shield offers less resistance therefore reducing load on the bearing giving a higher max rpm. Over time these bearings have been refined to provide the best possible type of rubber seal, and additionally the lubricant package has been refined to offer less resistance, more protection and longer life. These super rugged bearings are sure to give better life and better preformane than stock kit bearings.  Bearing Dimension: Internal 12mm External 18mm Width 4mm Bearings are supplied in a pack of 10 pieces. PLEASE NOTE: THE COLOUR OF THE RUBBER SEAL MAY VARY.
