Product Detail

PEEK / PI High Temperature Application Plastic Bearings As newly developing engineering plastic material, PEEK and PI have been approved have the strongest mechanical strength and could endure the highest temperature among all the plastic material. PEEK could work at 260 and PI at 300 in long time,The Density of PEEK plastic bearings is 1.32 g/cm3, Sliding friction coefficient is 0.30, Short-time highest application temperature is 300. Moreover PEEK / PI High Temperature Application Plastic Bearings have excellent anti-corrosion performance, could be used in strong acid and alkali environment. So generally PEEK / PI High Temperature Application Plastic Bearings are used to manufacture bearings to realize precision running in rigor environment. As the material is expensive, the costs are high. Generally the rings made with PEEK or PI, Cage with PTFE, PEEK or PI, and ball with ZrO2 or Si3N4. - - - - Basic properties of staple engineer plastic | Material | HDPE | PP | POM | PA66 | PVDF | PPS | PTFE | PEEK | Long-time working temp. | 90 | 100 | 110 | 100 | 150 | 230 | 260 | 280 | Density | g/cm3 | 0.91 | 1.42 | 1.14 | 1.77 | 1.35 | 2.18 | 1.32 | Ball indentation hardness | 50 | 80 | 170 | 170 | 80 | 190 | 30 | | Tensile stress | 25 | 30 | 70 | 80 | 50 | 75 | 25 | 95 | Sliding friction coefficient | 0.29 | 0.3 | 0.34 | 0.35-0.42 | 0.3 | | 0.08-0.1 | 0.3-0.38 | Melted temperature | 130 | 165 | 175 | 260 | 172 | 280 | 327 | 343 | Short-time highest application temperature | 90 | 140 | 150 | 170 | 150 | 260 | 260 | 300 | Coet of Inear expansion (10^-5/K) | 13-15 | 17 | 10 | 8 | 13 | 5 | 12 | 5 | Dielectric constant at 1 Mhz(10^6HZ) | 2.4 | 2.25 | 3.7 | 3.6-5 | 8 | | 2.1 | 3.2-3.3 | Volume resisrivity (cm) | >10^15 | >10^24 | >10^14 | 10^13 | 10^12 | >10^13 | 10^14 | 10^13 | flammability UL94 | + | + | - | (+) | (+) | - | + | + | Anti-weathering | - | - | - | - | - | - | + | - | Note: + =resistant; (+) =partly resistant; - =non-resistant | - - - - - - - - Chemical properties of Engineer plastic | Chemical Composition | Material | PI | PEEK | PTFE | PVDF | PA66 | POM | PP | HDPE | ABS | Acrtate | + | + | + | (+) | (+) | + | + | (+) | + | Formic acid (10% water) | + | + | + | + | - | - | + | + | + | Ammonia (10% water) | - | + | + | + | + | (+) | + | + | + | Aether | + | | + | + | + | + | + | + | | Petrol | + | + | + | + | + | + | (+) | (+) | (+) | Bori acid (10% water) | | + | + | (+) | + | + | + | + | + | Aminoform | + | + | + | | - | - | (+) | - | - | Aeti aid 100% | (+) | - | + | | - | - | + | + | - | Aceti aid (10% water) | + | + | + | | - | (+) | + | + | + | HF | | | + | | - | - | + | + | (+) | Formaldehyde aqu (30% water) | | + | + | + | + | - | + | + | + | Glycerin | + | | + | | + | + | + | + | + | Iodine, Glycol | + | | + | (+) | - | (+) | + | + | (+) | K2Cr2O7 (10% water) | | | + | + | + | - | + | + | + | KMnO4 (1% water) | + | + | + | + | - | (+) | + | + | (+) | 2-Hydronyprpionic 10% | + | | + | + | - | - | + | + | - | 2-Hydronyprpionic 90% | + | + | + | + | + | (+) | + | + | + | Nad (10% water) | + | + | + | + | + | + | + | + | + | NaNO3 (10% water) | + | | + | + | + | + | + | + | + | NaOH (50% water) | | + | + | + | + | - | + | + | + | NaOH (5% water) | | | + | + | + | - | + | + | | Oxalic (10% water) | + | + | + | + | (+) | (+) | + | + | + | Tetracarp | + | | + | + | (+) | + | - | - | (+) | H3PO3 100% | | + | + | | - | | | + | + | H3PO4 (10% water) | | + | + | + | - | - | + | | + | NHO3 (2% water) | + | + | + | + | - | - | + | + | + | HCL (2% water) | + | + | + | (+) | - | - | + | + | + | H2SO4 98% | | - | + | | - | - | + | (+) | - | Soap liquid | | | + | + | + | + | + | + | | Alkaliliquid (10% water) | | | + | + | + | + | + | + | + | Toluene | + | + | + | + | + | + | + | (+) | - | Water, cold | + | + | + | + | + | + | + | + | + | Water, hot | | + | + | + | (+) | - | + | + | + | H2O2 (30% water) | | (+) | + | + | - | - | + | + | + | H2O2 (0.5% water) | + | | + | + | - | (+) | + | + | + | Asphalt | + | | + | | (+) | + | (+) | (+) | | Note: + =resistant; (+) =partly resistant; - =non-resistant | | - - - -
