1, the overall plastic bearings are lubricated materials, long service life,
2, the use of plastic bearings will not rust and corrosion-resistant,
3, the quality of plastic bearings lighter than metal, which is more suitable for the modernization of lightweight design trends,
4, plastic bearing manufacturing costs are lower than the metal, plastic bearings are used injection molding is more suitable for mass production,
5, plastic bearings in operation without any noise, with a certain vibration absorption function,
Plastic bearing inner and outer ring materials generally use engineering plastics as raw material, some also have wear-resistant metal as raw material. Rolling generally use glass ball, stainless steel ball and ceramic ball. Glass fiber reinforced nylon 66 (PA66) and PE or High-performance engineering plastics.High-precision plastic bearings generally use precision CNC machining, bearings in the rotation accuracy and tolerance is better.Generally, many traditional plastic bearings are used by direct injection molding, solid forming a higher cost. (Pulleys are generally used in this process) for low speed, medium load occasions used in the toy industry, fitness equipment industry, furniture industry, medical machinery industry, advertising industry, there is a weak chemical corrosion of the industry have been widely used.
