Sliding friction occurs when sliding bearings are working; the magnitude of sliding friction mainly depends on the manufacturing accuracy; and the magnitude of friction of sliding bearings mainly depends on the material of the sliding surface of the bearing. Sliding bearings generally have a self-lubricating function on the working surface; sliding bearings are divided into non-metallic sliding bearings and metal sliding bearings according to their materials.
Non-metallic sliding bearings are mainly made of plastic bearings. Plastic bearings are generally made of engineering plastics with better performance. More professional manufacturers generally have engineering plastic self-lubricating modification technology, which uses fibers, special lubricants, and glass beads. And so on to improve the self-lubricating modification of engineering plastics to achieve certain performance, and then use modified plastics to process into self-lubricating plastic bearings through injection molding.
The most commonly used metal sliding bearing in the early 21st century is the three-layer composite bearing. This kind of bearing is generally based on carbon steel plate. A layer of spherical copper powder is sintered on the steel plate through sintering technology, and then the copper powder layer is sintered. The upper layer is sintered with a layer of PTFE lubricant of about 0.03mm; the main function of the middle layer of spherical copper powder is to enhance the bonding strength between the steel plate and PTFE, and of course it also plays a role in bearing and lubricating during work.
