PEEK Bearings

PEEK (Polyether Ether Ketone) bearings are advanced, high-performance components designed for demanding applications across various industries. Known for their exceptional strength, low friction, and outstanding wear resistance, PEEK bearings excel in environments where traditional metal or plastic bearings may fail. These bearings can withstand extreme temperatures up to 260°C (500°F) without losing their structural integrity, making them ideal for high-heat applications such as engines, aerospace systems, and industrial machinery.

In addition to heat resistance, PEEK bearings are chemically inert, providing excellent resistance to harsh chemicals, oils, and solvents commonly found in automotive, chemical processing, and food-grade environments. Their lightweight nature reduces the overall system weight while maintaining high mechanical strength and dimensional stability, making them particularly suitable for aerospace applications where weight reduction is critical.

Moreover, PEEK bearings are self-lubricating, reducing the need for external lubrication and minimizing wear and tear over time. This results in lower maintenance costs and enhanced longevity, ensuring reliable performance in high-stress environments such as automotive engines, transmissions, and industrial equipment. Whether used in aerospace, automotive, medical, or industrial sectors, PEEK bearings offer superior durability and precision, meeting the demands of modern, high-performance applications.

What is a PEEK bearing?

A PEEK bearing is a bearing made from a high-performance thermoplastic polymer called polyetheretherketone (PEEK). PEEK bearings are known for their ability to perform well in extreme conditions, including high temperatures and challenging environments.

Is PEEK good for bearings?

PEEK bearings can provide exceptional performance in high ambient temperatures and with low-viscosity lubricants such as water. It is also an electrical insulator and resistant to chemical attack.

What material is PEEK bearing made of?

PEEK is available in unfilled, 30% glass filled, 30% carbon filled, and bearing grade (ARKPEEK-MOD). Bearing Grade PEEK has been reinforced with carbon fibers with graphite and PTFE lubricants.
