Plastic bearing characteristics:
POM is also known as "saigang": it has good polyoxymethylene, also known as polyoxymethylene, and its English name is polyxymethylene (POM for short). The regular molecular structure and crystallinity make it excellent in physical and mechanical properties, and it is called metal plastic.
Advantages: good comprehensive properties and colorability, high elastic modulus, high rigidity and hardness, tensile strength, flexural strength, excellent creep resistance and fatigue resistance, resistance to repeated impact, and low coefficient of friction , Abrasion resistance, good dimensional stability, good surface gloss, high viscoelasticity, small water absorption, excellent electrical insulation, and not affected by temperature; small water absorption, good insulation resistance and not affected by humidity. The mechanical properties are less affected by temperature. It has high mechanical strength and abrasion resistance at thermal deformation temperature. It can be used in the temperature range of -40 degrees to 100 degrees. It is suitable for making relatively precise plastic bearings. Low coefficient of friction.
Disadvantages: not resistant to acid, strong alkali and moonlight UV radiation, poor thermal stability, easy to burn, easy to age in the sun, easy to decompose, and the decomposition temperature is 240 degrees. A wide range of materials. Generally, the inner and outer ball materials are made of POM. The cage is made of glass fiber reinforced nylon PA66. The balls are glass balls, stainless steel balls or ceramic balls. These bearings perform well in alkaline environments but are not suitable for acid corrosion run.
