Application of plastic ball is PA wide, PA plastic ball is also called plastic nylon ball, good abrasion resistance, no lubricating oil lubrication, the toughness is very high in all plastic raw materials is the best plastic toughness, so the plastic nylon ball used in all plastic ball most widely used in automobile parts, there are many application of high temperature environment of electrical components, used in plastic bearings in plastic ball PA is mainly because the nylon has good abrasion resistance and can be reused for more than 10000 hours, other plastic ball can not be compared, there is no oil lubricated performance without lubricating oil in the high temperature environment, which is. The metal ball can not be compared, as everyone knows no oil lubricated metal ball is easy to wear, bearing damage, so the plastic nylon ball bearing life is no better than the metal ball How much bearing difference.
