Product introduction of deep groove ball ceramic bearings

POM (polyoxymethylene) operating temperature range is from - 60°C to 100°C. Due to its high surface strength and smoothness, POM has excellent sliding properties and wear resistance. POM basically does not experience tension, and its copolymer has high thermal stability and chemical stability (it is worth paying special attention to its enhanced hydrolysis resistance) PA polyamide (nylon) is a high-precision engineering plastic, and polyamide has High strength, hardness and toughness, as well as high heat resistance and non-deformation (about 40°C to 100°C). Since good mechanical properties can only be achieved after the material temperature is suitable, it must be humidified again after annealing and grown in the air. Time storage can also reach the corresponding temperature.

PEEK (polyether rattan) material has high continuous use temperature (about +260°C) and also has stiffness and hardness. In addition, it has excellent heat resistance, non-deformation performance and chemical stability. The material has good dielectric properties until the temperature reaches 360°C, is resistant to energy rays, is flame retardant and self-extinguishing.

PTFE (polytetrafluoroethylene) has a long-term use temperature of -200°C+260°C. It has strong resistance to chemical corrosion and is resistant to all chemicals. It has a low coefficient of friction, good electrical insulation, and is not affected by Temperature effect

PVDF (polyvinylidene fluoride) has greater stiffness and pressure-bearing capabilities than its PTFE counterpart, but is less slippery and less electrically insulating. It has high strength and toughness under low temperature conditions and can self-extinguish. Its operating temperature is between -60°C + 150°C. PVDF is stable against chloride, bromide and energy rays. Both ester and copper solutions can corrode it at high temperatures.

HDPE (polyethylene) has good chemical stability and can resist the erosion of most acids, alkalis, organic solutions and hot water. It has good electrical insulation and is easy to weld. The working temperature is: -50°C+90°C.

PE-UHMW (high molecular weight polyethylene) has superior sliding properties than HDPE.
PP (polypropylene) has high stiffness and strength. High hardness, but average notch impact toughness. PP materials bear tensile stress and are easy to weld, become brittle at low temperatures, and have excellent chemical stability and electrical properties. It can resist the erosion of acids, alkalis, organic solutions and hot water, and the working temperature ranges from +5°C to +100°C.
