This is a replacement special rear bearing for Novarossi brand engines that require the 14mm internal diameter with 25.8mm external diameter. 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. This will work with any Novarossi brand engine including the Top and Rex lines, for engines such as the P5, 421B and BS-21SB.

Novarossi Special Rear Bearing 14x25.8x6 (P5X, 421BS, 528X)
This is the stock p5 bearing, and yes it costs more than twice what a cheap aftermarket ceramic bearing costs, but if you keep oil on it It will last forever. I promise.
