The China PEEK Shaft Sleeve from Ideal Plastic factory is a cylinder-shaped part that fits snugly around a shaft. It's one solid, continuous piece—not made from smaller bits stuck together—and the inside wall is smooth. Some versions even have a bit of a lubricating effect. The outside diameter matches the bearing housing perfectly, and the inside diameter fits the shaft just right. The wall thickness is pretty even all around, with no extra fixing bits like flanges or slots. Contact us!

4. Main Function: to protect the shaft and cut down on friction
The main point of the quality PEEK Shaft Sleeve provided by Ideal Plastics manufacturer to reduce friction and protect the shaft. That’s why it’s made from PEEK—it’s self-lubricating and wears really well. PEEK plastic naturally lubricates itself, so you don’t need to add oil or grease. That means it can run without oil or with very little oil, which saves a lot on maintenance costs. It also has a very low coefficient of friction and a low wear rate, so friction between the shaft and bushing is noticeably reduced. That protects expensive shafts and makes them last longer. On top of that, PTFE and graphite are added to boost PEEK’s self-lubricating and wear-resistant properties even further. That’s why we call it “bearing-grade PEEK Sleeves.”

PEEK base material features inherent low-friction surface characteristics, eliminating the need for regular oil or grease lubrication during operation. After compounding with specialized functional fillers, the friction coefficient is reduced to 0.15, achieving ultra-low wear loss and reliable dry-running capability. The composite PEEK sleeve maintains stable friction and wear performance even under harsh working conditions including elevated temperatures, heavy mechanical loads and high-speed cyclic operation, delivering exceptional durability for long-service mechanical components.
This PEEK Shaft Sleeve exhibits outstanding chemical stability against most conventional corrosive media, including common acids, alkalis and various organic solvents. It features clear and reliable application boundaries: it is only susceptible to corrosion by concentrated sulfuric acid and slight discoloration from concentrated nitric acid. Incompletely crystallized PEEK materials may develop cracks in acetone-based solvents, while fully crystallized finished products adapt steadily to diverse complex liquid working scenarios without performance degradation or structural damage.
Outperforming ordinary plastic materials and matching the fatigue resistance of many metal components, PEEK sleeves withstand over ten million cycles of repeated mechanical stress and high-frequency vibration. It avoids fracture, structural loosening or fatigue failure after long-term cyclic operation, making it a reliable choice for high-demand core parts such as compressor rotors, transmission gears, bearing bases and valve structural components.
With high inherent resin rigidity and ultra-low thermal expansion coefficient, PEEK material delivers aluminum-alloy-level dimensional stability. The finished shaft sleeves resist thermal warping, structural deformation and high-temperature cracking under fluctuating heat environments, maintaining precise assembly dimensions and structural integrity for long-term high-temperature industrial operation.
The material possesses prominent anti-creep properties, effectively resisting permanent structural deformation caused by sustained mechanical stress. It retains complete geometric shape and stable mechanical performance during prolonged constant-load operation at high temperatures, solving the loose assembly and precision failure problems easily occurring in ordinary plastic parts under long-term stress.
Ranked first among mainstream engineering plastics in steam and hydrolysis resistance, our PEEK sleeves endure thousands of hours of continuous operation in 260°C high-temperature steam and high-pressure hot water with negligible performance attenuation. It supports stable long-term service in 200–250°C steam environments, perfectly adapting to high-temperature and high-humidity harsh industrial working conditions.
Our PEEK shaft sleeves are available in three professional material grades, including virgin pure PEEK, CF30 carbon fiber reinforced PEEK, and HPV wear-resistant modified PEEK. With customized fillers such as PTFE and graphite, the material achieves professional bearing-level performance, specifically engineered for friction reduction and shaft protection scenarios.
