Quick Details
SF-1 oil free self lubricating bearing foreign said (Du). This series of products is based on the steel plate as the matrix, intermediate sintering spherical bronze powder, surface rolling of the mixture of PTFE and lead, the sliding bearing. The characteristics of small friction coefficient, wear resistance, good corrosion resistance and no oil lubrication. " O using this product can reduce the cost, reduce the mechanical volume, avoid the phenomenon of the bite shaft and reduce the mechanical noise and so on. & nbsp; < B style = "mso-bidi-font-weight:normal; > application characteristics 1. & nbsp; & nbsp; & nbsp; & nbsp; < / b > applicable to refuel or difficult to refuel place, when in use without maintenance. Style= mso-bidi-font-weight:normal "2. wear resistant performance is good, the friction coefficient is small, the service life is long. < B style = "mso-bidi-font-weight:normal;" >3. & nbsp; & nbsp; & nbsp; & nbsp; < / b > static dynamic friction coefficient are similar and eliminate the low-speed crawling, so as to ensure the accuracy of the mechanical work. < B style = "mso-bidi-font-weight:normal;" >4. & nbsp; & nbsp; & nbsp; & nbsp; < / b > can make the machinery to reduce vibration, reduce noise, prevent pollution, improve and optimize the working environment. < B style = "mso-bidi-font-weight:normal;" >5. & nbsp; & nbsp; & nbsp; & nbsp; < / b > for grinding shaft hardness requirements low, not the shaft of the quenching and tempering treatment can be used, reduce the related parts of the processing difficulty and cost. Style= mso-bidi-font-weight:normal "6. thin wall structure, light weight, section to reduce the volume of machinery. < B style = "mso-bidi-font-weight:normal;" >7. & nbsp; & nbsp; & nbsp; & nbsp; < / b > steel on the back can be a variety of metal plating can be used in the corrosive medium; at present, it is widely used in a variety of mechanical sliding parts, such as automation machinery and equipment (stretching, swing, sliding and bending, convoluted and rotary parts) hydraulic cylinder guide sleeve, hydraulic motor, gear pump, textile machinery, automatic vending machine, plastic injection molding machine, die casting machine, rubber machinery, tobacco machines, fitness equipment, office machinery, hydraulic truck, automobiles, motorcycles, machinery for agriculture and forestry, etc..
