ProTek RC 7x19x6mm "Speed" Front Engine Bearing (Samurai, O.S., Novarossi, RB)
About this part
This is a rubber sealed "Speed" front bearing from ProTek R/C. This bearing is designed to fit the O.S. MAX .21 RG, VZ-B and VZ-B V-Spec off-road competition buggy engines. This bearing will also fit any other .21 competition buggy engine that uses the same bearing dimensions, such as the RB Concepts WS7, WS7II, Top P5 etc. The bearing dimensions are 7mm inner, 19mm outer and 6mm thick. This bearing is sealed to stop fuel leaking out the front of the engine during use.
Dual Front and Rear Seals
These bearings come with seals on both the front and rear of the bearing. Some people prefer to install the bearing with both seals intact, however we recommend that you remove the seal from the side of the bearing that will be going into the engine, to ensure that the balls in the bearing get the proper amount of lubrication.

Impressed with the value of this bearing from Protek. Great quality.
Bearing is smooth but it leaks quite a bit. It was spraying a little fuel and oil just priming the engine. I’m gonna stick with it for a bit and see if it causes my problems while running, but for future reference, just get the $20 bearing for the samurai. It’s the same as the OS front bearing and that one works phenomenally
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.
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.
Reviewers are divided on this 7x19x6mm front engine bearing. Two reviewers praise its smooth spin, quality construction (including a plastic retainer similar to Nova bearings), and value for money, and note the photos match the product. One reviewer reports it leaks fuel and oil during priming but plans to keep testing it, and another reports it lasted only two races in a Novarossi engine, with visible gap between the rubber seal and inner flange. Reviewers also suggest a different Samurai-compatible bearing as an alternative. The sample is small (four reviews) and the reviews mention different engines, so long-term durability remains unclear.
