10pcs Hobbypark Micro Ball Bearings 3x6x2mm Metal Shielded for RC Car Quadcopter Helicopter Replace Traxxas - 6642

Good smooth bearings! although I had to go through them as some were BETTER than others. none were bad, but some you could feel it wasn't as smooth as it could have been.

product seems to perform well and spin blades faster, also it does fit the mjx x600 perfect but time will tell how long it takes a motor to burn out now, thank you Hobbypark!!!

Great set of bearings. Replaced the inferior bushings in my MJX600 hexacopter with these. Direct fit replacement and had extras for my spare motors. They've been running great.

Bought them for something else, but realized they work as replacements for the bearings on the gt2 pulleys that I have on my 3d printer.

Several of the bearings did not turn freely, Had to sort through them to get 4 that were just ok. I suppose they were ok for the price but the quality was not particularly good.

Excellent quality at a very nice price.

Ordered these to replace the solid brass provided with Plastic WPL axles. They worked like a charm, and came with just the right amount to do both rear and front portal axles. Increases your battery time, gives you more torque, well worth the upgrade cost.
