Dry Thrust Washer

Steel PTFE washers, bronze Polytetrafluoroethylene washers, and ceramic washers are all types of washers that are commonly used in mechanical applications to prevent leakage, reduce friction, or provide a seal. However, they differ in terms of their material composition, properties, and applications.

Steel PTFE washers are made of a steel core coated with a layer of PTFE (polytetrafluoroethylene), a synthetic fluoropolymer with high chemical resistance, low friction, and non-stick properties. These washers are typically used in applications where chemical resistance, temperature resistance, and low friction are important, such as in the chemical processing, food and beverage, and medical industries.

Bronze Polytetrafluoroethylene washers are made of a bronze core coated with a layer of Polytetrafluoroethylene (PTFE). The bronze core provides strength and stability, while the Polytetrafluoroethylene coating provides low friction and chemical resistance. These washers are commonly used in applications where moderate to high loads are encountered, such as in hydraulic systems, pumps, and valves.

Ceramic washers are made of ceramic materials, such as alumina or zirconia, which have high hardness, high temperature resistance, and excellent wear resistance. These washers are typically used in applications where high temperature, high pressure, and wear resistance are important, such as in automotive engines, turbines, and high-pressure pumps.

In summary, steel PTFE washers are best suited for applications where chemical resistance and low friction are important, bronze Polytetrafluoroethylene washers are best suited for applications where moderate to high loads are encountered, and ceramic washers are best suited for applications where high temperature, high pressure, and wear resistance are important.
