This is the replacement main bearing for the RB Concepts "MSC" line of engines, as well as teh Buggy 9, and Monster Truck 9 engines. The main-bearing of the RB CONCEPT MSC series is featured with 2 rubber shields(inside and outside) to prevent dust or water to come into the engine and deteriorating the bearing itself. The 14mm main-bearing is of very high quality and has its line of balls placed more close to the connecting rod to get a better stability of the crankshaft.
