The salt water test in lab: engineering plastic ball bearing VS metal ball bearing

The salt water test in lab: engineering plastic ball bearing VS metal ball bearing 2019 - 05 - 20 in cologne headquarters, igus company which runs the world's biggest sports plastic test lab. Here each year to more than 12000 times wear resistance test, including testing all kinds of engineering plastics in the different working conditions. This time, xiros ball bearings and metal ball bearing is placed in the salt water for performance comparison. By free of lubrication and maintenance free of wear resistant engineering plastic xiros ball bearing in the test experiments showed the excellent performance of the compelling. Igus test engineer in a container filled with water and heated to + 80 ℃. Then two test ball bearing placed among them, 120 hours of observation. One is the standard 2 hole flange bearing made of metal, the other one is by xirodur B180 xiros flange made of ball bearing. Xirodur B180 is a high-performance engineering plastics, medium resistance and wear resistance. In testing, not fully covered by salt water, the two bearing part exposed to the air to trigger the corrosion effect. Hours later, the metal ball bearing corrosion test results be clear at a glance. Hours later, metal corrosion to occur in the ball bearing. At the end of the test, which is 120 hours, the metal ball bearing can see obvious rust. Engineering plastic bearing is different. In salt water corrosion and high temperature heated after 120 hours, xiros flanged ball bearings still hasn't been affected. No color change, no rust marks. This advantage makes it very suitable for clean room medical application and food technology, can avoid health risks due to rust. Xiros ball bearing usually consists of four parts: the inner ring and outer ring, made of engineering plastic cage, and made of stainless steel or glass ball. Unlike metal ball bearing, wear resistant engineering plastic bearings can be very smooth and health run dry, without lubricants, and free maintenance. They not only service life is long, and can calculate online. In addition, engineering plastic bearing is electrical insulation, non-magnetic, applicable temperature range is - 40 ℃ to + 80 ℃, compared with the similar metal bearing, light weight 60%, cost reduced by 40%. They are suitable for medium load application and high reliability, have long been tourist destinations for global customers for many years, used to label the conveyor belt, transmission and packing machine and filling machine and other equipment.
