Applications: Food processing Packing machinery. Electrica l machinery Washing machines Converting sections Finishing Ventilators Power tools Advantages: 1. Lower noise level(50 percent less noise) 2. Lower friction(35 percent less friction) 3. No dust ever(Robust, reliable and durable) 4. Improved sealing action 5. Higher cost-efficiency Quality Assurance: Race: we use the most advanced technology-cold extrusion process. Besides, the race will make two or three times temper to guarantee its high precision. Rolling element: we use the rolling technology to process the roller and the steel ball of high precision bearing, the most advantage of our technology is to promote productive and productive efficiency. At the same time, our technology can prolong the bearing working life. The hardness and the diamention stability will also promote. Steel cage: in order to avoid avoid cracks and guarantee the hardness, we use pattern "high temperature+long time", our cage of high precision bearing have reached advanced level in china at surface abrasion resistance and fatigue strength.
