Review on F**KG 6200 ZZ 10x30x9mm Pre-Lubricated Bearing by Brad Ward

From an engineering point of view these are quality bearings for my (specific) windmill application. I chose it for the stainless steel seals (as opposed to rubber seals) plus descriptions and hope for the best. The bearings came individually wrapped in plastic bags and boxes. Fits perfectly and my spinner now spins much smoother than the original. Just measure your old bearing rings carefully as many bearings are very similar in size and different applications use different sizes.
