    Common Bearing Engineering Challenges and their Solutions

Corrosion
  • Plastic bearings never rust or corrode
  • Tolerate chemicals and abrasives
  • Stainless steel liner options
  • Extended service life and wear over metals
Lubrication
  • Self-lubricating bearings never need grease 
  • Eliminate worries of lubrication levels and contamination
  • Require zero maintenance
  • Save on expensive materials and labor
Service Life/Wear
  • Metal bearings can lead to early failure
  • Lubricants attract dirt and grit that contaminate metal
  • Range of temperatures and sizes
  • Shifting and misalignment no problem with plastics
Efficiency
  • Energy-loss inherent in metals increase costs
  • Low-friction polymers reduce operation costs
  • Highly-customized plastics are more efficient
  • Composite plastics maximize cost/performance ratio
Size/Weight
  • Composites reduce size/weight
  • Self-lubricating bearings offer thinner designr
  • Bronze bearings are bulky and heavy
  • Plastic bearings up to 5x lighter than steel
Bonding/Adhesion
  • Alter surface energy of plastics 
  • Plastics can be bonded to other materials
  • Range of bonding and adhesion techniques
  • Bonding application expertise and uniformity is key
Noise/Vibration
  • Metal bearings cause noise, require grease
  • Self-lubricating plastics eliminate grease, reduce noise
  • Polymers and composites absorb harsh vibrations
  • Insulated design for better performance
Agency Approval
  • Look for quality control and industry certification
  • FDA, USDA, NSF, EU, ABS-compliant materials
  • Sanitation for food industry, pharma, medical
  • Marine shipping-compliant for both dockside and onboard
