Peek in Bearing Material


Due to its excellent mechanical strength, dynamic fatigue resistance, high-temperature resistance, creep resistance, self-lubrication and thermal expansion coefficient comparable to metals, PEEK material is replacing more metals and other engineering plastics for automotive parts in the future to adapt to the trend of auto lightweight, improve fuel economy and withstand higher operating temperature.


Applications: Steel-backed Bearings/ Seat Adjusters/ Abs Valve Seats/ Vane Pumps/ Gear Pumps/ Bearing Retainers/ Hydraulic Valves/ Turbine Pumps/ Door Modules/ Electronic Parking Brakes


Advantages of Peek over Traditional Bearing Materials


PEEK (Polyetheretherketone) has become increasingly popular in the design of bearings due to its superior mechanical and thermal properties, which allow it to replace traditional bearing materials such as bronze, stainless steel, and PTFE. Some of the advantages that Polyether Ether Ketone bearings offer over traditional bearing materials include:


  • High Wear Resistance: PEEK is resistant to wear and exhibits a low coefficient of friction, making it a suitable material for use in bearings.

  • Low Friction: PEEK offers low friction and can improve energy efficiency, resulting in reduced energy consumption and longer lifespan of the machinery.

  • High-temperature Resistance: PEEK can withstand temperatures up to 260°C (500°F), which is much higher than traditional bearing materials, making it ideal for high-temperature applications.

  • Corrosion Resistance: PEEK's excellent resistance to harsh chemicals, such as acids, bases, and solvents, makes it suitable for use in corrosive environments.

  • Lightweight: PEEK has a specific gravity almost half of that of steel, making it a suitable alternative for applications requiring lightweight bearings.

  • Excellent Mechanical Properties: PEEK's high strength, toughness, and impact resistance make it ideal for use in heavy-duty bearing applications.


In summary, PEEK from Zypeek offers several advantages over traditional bearing materials like bronze, stainless steel, or PTFE. Its ability to withstand high temperatures, resistance to wear and corrosion, lightweight, low friction, and superior mechanical properties make it a preferred material choice for bearings in various industries, benefiting from improved efficiency and endurance.


Peek Bearing Material


PEEK (Polyether Ether Ketone) is increasingly used as a preferred material for bearing applications. PEEK bearing materials offer several advantages over traditional bearing materials such as bronze, stainless steel, and PTFE.


PEEK is an ideal material for a bearing because it can withstand harsh environments, offers superior mechanical properties, is lightweight, and has excellent wear resistance. PEEK bearings also have a low friction coefficient compared to traditional bearings, making them an attractive option for applications requiring low friction and low energy consumption.


PEEK bearing materials are also resistant to temperature changes, retaining their mechanical properties at high-temperature ranges up to 260°C (500°F), making it a suitable material for high-temperature bearing applications.


Moreover, PEEK bearing materials also exhibit excellent resistance to corrosion and harsh chemicals such as acids, bases, and solvents, making it a desirable material for bearings in corrosive environments.


In summary, PEEK material applications provide several advantages as a bearing material choice due to its superior mechanical properties, low friction coefficient, high wear resistance, and remarkable temperature and chemical resistance.
