The ZGXL 62301-2RS/C3 12x37x17mm single row, deep groove ball bearing, offers versatility and overall high performance. The sealed ball bearing is fitted with synthetic rubber seals to prevent dirt and other items entering the bearing. It is primarily intended for use where the inner ring rotates, engineered with a wider profile than standard series bearings. ( Commonly used for a tensioner pulley on the Lexus 1uz/3uz Engen.)
