Matrix 8mm CNC Precision Steel Ball Bearing Bushing for Airsoft AEG
by Colin H. Date Added: November 5, 2012
I bought these also to replace the brass bushings on my g4-a3. The bearings fit quite perfectly in my gearbox even thought there was SIGNIFICANT wear from the brass bushings in the bushing holes. The bearings function very smoothly. It is my final addition to solving the g4-a3's motor heat issues. The bearings provide a nice smooth rotation for the gears. With my bushings i got 3 rotations with a perfect shim. With these I got around 8 and half rotations on a single flick of my finger when perfectly shimmed! Very nice quality and price.
