Nylon is one of the most widely used and versatile thermoplastic resins. Its combination of physical properties and reasonable price make it a favorite choice for numerous applications. Nylons toughness, wear resistance, tensile strength and lubricity make it a good choice for many mechanical machine parts.

- Nylon has a consistent history of replacing other materials including: metal, brass, bronze, aluminum and rubber. In replacing metal gears in machinery, Nylon can be advantageous because of its ability to reduce noise, use less lubrication and increase gear life. It can also be lighter weight as Nylon weighs 1/7 as much as Bronze. Nylon can also be fabricated on most mills with high precision.

Cast Nylon exhibits all the properties which generally make nylon a superior engineering material: high strength, low friction and wear resistance. However, because of the casting process, part size and thickness are almost unlimited without degradation of the materials internal structure. Cast Nylon meets FDA standards.


  • High impact resistance
  • Excellent vibration resistance
  • Resistance to brittleness and deterioration
  • Easy to machine and fabricate
  • Good abrasion resistance
  • High heat distortion temperature


  • Gears & sprockets
  • Bushings & bearings
  • Wear shoes & pads
  • Sheaves & pulleys
  • Feed screws
  • Wear rails & strips
  • Scraper blades
  • Supports
  • Housings

Engineering Note:

Nylons can absorb up to 7% (by weight) water under high humidity or submerged in water. This can result in dimensional changes up to 2% and a corresponding reduction of physical properties. Proper design techniques can frequently compensate for this factor.
