This is a ceramic rear engine bearing from TKO Competition Development designed to fit the Novarossi Plus 21-5 and Plus 21-7 off-road competition buggy engines. This bearing also fits recent Novarossi and RB Concepts engines that require the special 14.5x26 mm rear bearings. The bearing dimensions are 14.5mm inner, 26mm outer and 6mm thick. This bearing is open to allow oil to lubricate the bearings during use. This bearing will also fit any other .21 to .28 competition engine that uses the same bearing dimensions.
NOTE: This bearing should be installed so that the balls face
the rear of the engine (towards the backplate), in order to allow
proper lubrication.
