This is a R/C 14x25.8x6mm Ceramic Rear Engine Bearing, and is intended for use with Novarossi P5X, 528X and RB Concepts TM928 off-road competition buggy and truck engines. This bearing also fits all any other engine that requires a 14x25.8x6mm rear bearing. The bearing dimensions are 14mm inner, 25.8mm outer and 6mm thick. This bearing is open to allow oil to lubricate the bearings during use.
NOTE: This bearing should be installed so that the balls face the rear of the engine (towards the back plate), in order to allow proper lubrication.
