Hey, I do not get how my kimbrough 100T spur gear has ball bearings in it. What does it do? What is advantage over a non ball bearing spur gear?

kimbrough offers most of their spur gears either with or without the ball bearings. the ball bearing are for direct drive cars like 1/12 and 1/10 pan cars. otherwise they are unused. also i dont know the quality of the ball bearings so you might not want to use them anyways.

That makes more sense than what I thought they were for...I figured they were for rotating mass, maybe to reduce drag brakes or something...
