Features of Plastic PEEK Ball Bearings

6 Published by admin Aug 12,2026

Peek ball bearings are special engineering plastic bearings made from polyetheretherketone (PEEK).Which have characteristics such as high temperature resistance.Self-lubricating.And high mechanical strength. This product has corrosion resistance, aging resistance, radiation resistance, abrasion resistance and hydrolysis resistance.And can still maintain dimensional stability and electrical insulation.Under high temperature and high pressure environment. It can replace metal for manufacturing lightweight precision parts. Its applications cover the manufacturing of mechanical equipment such as automotive brake system components.Engine high-temperature components.Aviation precision gears.As well as industrial fields such as medical device artificial bones.Hemodialysis machine parts.Semiconductor tools, etc. It also adapts to the high-temperature and high-pressure working environment of electronic components such as special cable sheaths and lithium battery seals.And extends to refrigeration, deep well oil pumps, high-speed gearboxes, and other fields. PEEK radial sliding bearings are used in high-speed heavy-duty gearboxes.And have applications in high-end equipment supply chains in Europe.

The common types of PEEK ball bearings include self-aligning ball bearings.Angular contact ball bearings, etc. The typical structure is that the collar is made of PEEK material.The rolling elements are made of zirconia ceramic balls.And the retainer is made of stainless steel 304 or PEEK material.
The product size range covers an inner diameter of 3mm or more. Using PEEK raw materials.It has good mechanical properties, heat resistance, corrosion resistance.And meets relevant hygiene standards. Its long-term use temperature can reach 260 ℃.And its short-term temperature resistance is 300 ℃.

PEEK ball bearings are expected to experience rapid growth. The demand for automotive lightweighting, robotics.High-end equipment manufacturing and other fields continues to expand. Represented by the entry of some domestically produced PEEK bearing products into the high-end equipment supply chain in Europe.Technological breakthroughs are helping them expand into the international high-end market.Reflecting the development direction of technological breakthroughs and market internationalization in the industry.
