Introduction to the characteristics of plastic linear bearings. In recent years, engineering plastic products have been widely used due to their excellent performance. Engineering plastics have broad prospects for use in bearings, and more and more users are welcome to use them. Because engineering plastic bearings have excellent self-lubricating properties, wear resistance, low friction and special anti-seizing properties, they can work well even under poor lubrication conditions, so they are very suitable as bearing materials. Therefore, for related engineering plastic bearing companies, the market prospects are very broad, and they should make full use of market opportunities and develop related plastic bearing products.
It has been found that HDPE, PP, UPE materials are used in relatively weak acid-base cross-linking environment (30% Cucl2 solution and 30% NaoH solution, fully tested), and thus are suitable for most acids/bases/salts/solvents/ Oil/gas and seawater corrosive environments. It has the characteristics of self-lubrication and oil-free anti-magnetic insulation of ordinary plastic bearings, but its mechanical strength is low and it is easy to deform. Thus, these acid-resistant plastic linear bearings are not suitable for large loads and high speeds to overcome the acid resistance.
In contrast, UPE materials have better strength, low friction properties and low temperature (up to -150°C) use characteristics. The general material of the inner ring and outer ring is HDPE, PP or UPE, and the material is HDPE, PP or UPE. The ball is a crystal ball, a stainless steel ball or a ceramic ball. The comprehensive performance of this plastic linear bearing will be greatly improved.
