China best Plastic PA66 Pulley with Double Bearing air compressor oil

China’s Best Plastic PA66 Pulley with Double Bearing Air Compressor Oil

Our high-performance Plastic PA66 Pulley with Double Bearing Air Compressor Oil is the perfect solution for all your industrial needs. Made from monomer casting nylon (MC nylon), this engineering plastic offers superior mechanical properties compared to other nylon materials like PA6 and PA66. With a molecular weight of 70,000-100,000/mol, our MC nylon pulleys provide exceptional wear-resistance, corrosion-resistance, self-lubrication, vibration-absorption, and noise-absorption.

MC Nylon: Revolutionizing Industrial Applications

Since the late 1980s, our company has been dedicated to developing and perfecting the technology of MC nylon modification. By incorporating various additives like lubricants, molybdenum disulfide, graphite, glass fiber, and carbon fiber during the reaction process, we have enhanced the properties of MC nylon, making it an ideal substitute for materials like bronze, stainless steel, babbitt alloy, and PTFE. Not only does it offer improved performance, but it is also cost-effective due to its simple manufacturing process.

Oil Nylon: Unmatched Lubricating Performance

Our Oil Nylon (Green) is a groundbreaking engineering plastic that incorporates a liquid lubricant system during the processing stage. This innovative design results in a lower coefficient of friction compared to general PA6 or PA66 plastics, making it perfect for non-self-lubricating, heavy-loading, and low-speed-running parts. With a wear-resistance that is 10 times greater than general plastics, our Oil Nylon significantly increases the bearing life, surpassing even phosphor bronze. The lubricant within the material remains constant throughout its service life, ensuring consistent performance and offering additional benefits like improved wear rate, sliding friction, abrasion resistance, and stick slip performance.

Other Casting Nylon Options

We also offer a range of other casting nylon options to meet various industrial needs:

  • Oil Nylon + Carbon (Black): This variant of oil nylon is reinforced with carbon, resulting in a compact and crystal structure. It offers exceptional mechanical strength, wear-resistance, anti-aging properties, and UV resistance, making it ideal for manufacturing bearings and other wear mechanical parts.
  • Oil MC901 (Blue): This improved MC nylon features a striking blue color and offers superior toughness, flexibility, and fatigue-resistance compared to general PA6/PA66 plastics. It is the perfect material for gears, gear bars, transmission gears, and more.
  • MC Nylon + MSO2 (Light Black): By adding MSO2 to MC nylon, we retain the impact-resistance and fatigue-resistance of casting nylon while improving loading capacity and wear-resistance. It finds wide applications in the production of gears, bearings, planet gears, seal circles, and more.
