Matrix 8mm CNC Precision Steel Ball Bearing Bushing for Airsoft AEG
by James Z. Date Added: October 1, 2011
Great bearings!
fitted them into my G&G G4-A1 after i had a bronze bushing completely fail on me and destroy my spur gear (and later I believed cause my sector gear to fail a month or two later) any way bearings spin nice and free and also made my gear box a little bit quieter
when your shooting 330FPS @ 25RPS with an 11.1v 30C lipo its nice not to have a loud whining noise in your ear
and they spin SOOOO smooth its great also made shimming easier to do in the gun (could tell if too many shims were put in causing it to bind up)

All in all
precision made
made to exact specs (8mm O.D. X 3MM I.D)
no metal shield which allows grease to get in to lubricate)
large diameter "balls" in the bearing (chance of failure is MUCH smaller then compared to 6 or 7mm bearings I've seen way to many of those fail on my friends guns)

none that I have come across
well maby price but its worth every penny!!
