Why Do Engineering Plastic Bearings (PEEK/PI/PPS) Replace Metal Bearings?

In scenarios requiring lightweight, corrosion resistance, insulation, self-lubrication, oil-free, quiet and waterproof performance, engineering plastic special bearings are rapidly replacing metal bearings and becoming a new trend in medical treatment, food, semiconductors and intelligent equipment.


Mainstream Special Engineering Plastics

  1. PEEK
    • Temperature resistance up to 250℃, high strength, wear-resistant and self-lubricating
    • First choice for medical, semiconductor, aerospace and high-precision equipment

  2. PI (Polyimide)
    • Temperature resistance over 300℃, ultra-high precision, ultra-low outgassing
    • Vacuum, aerospace and high-end testing equipment

  3. PPS
    • Chemical resistance, dimensional stability, flame retardant and cost-effective

  1. POM, UPE, PVDF
    • Self-lubricating, waterproof, quiet and low-cost


    • Irreplaceable Advantages of Plastic Bearings

    • Fully self-lubricating, no oiling and maintenance-free
    • Insulating, non-magnetic and anti-static
    • Waterproof, acid and alkali resistant, and rust-proof
    • Ultra-lightweight, only 1/5 to 1/8 of steel
    • Low noise, low vibration and no damage to mating shafts
    • Non-polluting and dust-free, suitable for clean rooms


    Typical Applications

    • Medical equipment, surgical instruments, laboratory instruments
    • Food machinery, cleaning equipment, conveyor belts
    • Semiconductor, photovoltaic and LCD panel manufacturing equipment
    • Precision instruments, optical equipment, quiet transmission
    • Underwater equipment, chemical anti-corrosion mechanisms


    Engineering plastic bearings are the optimal special material solution for lightweight, oil-free, quiet and clean equipment.
