Door-hinge solutions incorporating PTFE (Polytetrafluoroethylene) bushings offer superior performance and durability in various door applications. PTFE, commonly known as Teflon, is a synthetic fluoropolymer that exhibits excellent properties such as low friction, high chemical resistance, and exceptional temperature tolerance.
The incorporation of PTFE bushings in door hinges significantly reduces friction and wear, resulting in smoother and quieter door operation. This not only enhances the user experience but also extends the lifespan of the hinges.
Moreover, PTFE bushings are resistant to a wide range of chemicals, including acids, bases, and solvents, making them suitable for applications in harsh environments. They can also withstand extreme temperatures, ensuring reliable performance even under demanding conditions.
Door-hinge solutions with PTFE bushings are widely used in commercial, industrial, and residential settings. Wh it's a heavy-duty warehouse door or a delicate interior door, PTFE bushings provide an efficient and long-lasting hinge solution.
In summary, door-hinge solutions featuring PTFE bushings offer numerous benefits, including reduced friction, enhanced durability, and superior chemical and temperature resistance. They are an excellent choice for achieving smooth and reliable door operation in various applications.
PTFE lined self-lubricating bearing also called bushing, dry bushing, bearing, bushing,PTFE coated bearing,SF-1 oilless bearing,PTFE liner metal polymer composite bearing and PTFE based plain bearing. This type of bush takes PTFE layer as sliding layer which makes products can perform very well under dry condition or oil condition.
self-lubricating bearing bushings material has good thermal conductivity, and wear resistance. The stainless steel backing improves the mechanical strength of the bearing as well as to allow thicker bearing wall designation requirement. Stainless steel has a good chemical resistance feature.
1. PTFE Fibre Mixture, provides wear resistance and self-lubricating feature.
2. Stainless Steel Mesh , provides thermal conductive property.
3. Stainless Steel Backed bushings provides mechanical strength and corrosion resistance.
