ProTek RC 7x19x6mm "Speed" Front Engine Bearing (Samurai, O.S., Novarossi, RB)
I am impressed with the quality of these bearings. The first thing I did was pull one seal off to inspect the inside. It has a plastic retainer that resembles the Nova bearings, and spins smooth. This is a step up from other inexpensive front bearings that I have seen. The picture is accurate besides the seals are black unlike some other bearing companies that show one like this but you end up with something that is obviously inferior.

ProTek RC 7x19x6mm "Speed" Front Engine Bearing (Samurai, O.S., Novarossi, RB)
mounted in novarossi 21.plus-4 and it last only 2 races. I can see the day light between the rubber sheet and the inner flange. I am not convinced in the quality of these bearings.
