Product Detail

POM HighPrecision Plastic Bearings Plastic bearing made with POM is the most extensive sort of all the plastic bearings. Material POM have excellent mechanical strength and wearing resistance, POM High Precision Plastic Bearings is suitable for manufacturing precision plastic bearings. The Density of POM plastic bearings is 1.42 g/cm3, Sliding friction coefficient is 0.34, Short-time highest application temperature is 150. Generally the inner and outer rings made with POM or PA, Cage made with PA66 and the balls made with glass, stainless or ceramic. With good self-lubrication performance and low friction coefficients, POM High Precision Plastic Bearings could be used in precise and high speed application. POM High Precision Plastic Bearings could be used in some alkaline environment but not proper to some acid corrosion environment. - - - - 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 | | - - - -
