Suitable for high-speed operation This Is A Precision Deep Groove Ball Bearing, and widely used in precision instruments /micro motor/remote control model /RC racing ,etc. Product description SF-1 oil-free lubrication bearing is the rolled sliding bearing based on the matrix of steel plate, with the porous bronze powder sintered in the middle while the mixture of PTFE and lead rolled in the surface. It is with small friction coefficient, wear resistance, good corrosion resistance and oil-free lubrication. The application of such product can reduce the cost, reduce the mechanical volume, avoid the shaft engagement, and lower the noise. SF-1F oil-free lubrication bearing Metallographic analysis and material structure 1. Mixture of PTFE and lead 0.01-0.03mm 2. Porous bronze powder 0.2-0.3mm 3. Steel backing 0.7-2.3mm 4. Electroplated coating: thickness of tin coating 0.005mm, or that of copper layer 0.008mm The bearings are sealed on both sides to keep lubricant in.
University of Kentucky Football punter Colin Goodfellow demonstrates what's wildly possible, both on the field and in the classroom. “It’s (UK) the only school in the country that let me do nursing and football at the same time. And I was the first one to do it.”
