Review on Uxcell 012274 SCS12UU Linear Bearing by Fred Meeks

These are just what the hobbyist needs and they are the same items you will find in Asian made tools. They're a bit noisy and snappy. I prefer Delrin and Teflon (AF) bearings for their smoothness and smoothness in light conditions. Since we ship the majority of all consumer goods to Asia, it makes sense that they would also sell us individual parts. The only items we make in the USA are for military and commercial use and are incredibly expensive. Social Comment: Too bad we don't have to teach science in this country anymore. The average German housewife knows science and business better than our politicians.
