Sustamid® 6G - ASTM

PA — PA 6 G

QR-Code

Characteristics

  • Good sliding properties
  • Self-lubricating
  • Low "stick-slip" effect

Application Examples

Rollers

Thanks to their outstanding abrasion resistance, high mechanical strength and toughness, Sustamid® 6G rollers machined to close tolerances wear less than steel, require little maintenance and so offer a very long service life.

Castors

Castors -Castors made of our materials Sustamid® 6G and Lamigamid® machined within tight tolerances are subject to less wear than steel because of their excellent abrasion resistance and high mechanical strength and toughness, are low-maintenance and thus make for a very long servicelife. We would be happy to advise and support you in selecting materials, designing and performing stress computations.

Sliding element for the jib

Sliding elements made of lubricant enriched cast polyamides make for a smooth extension motion of telescopic crane booms and equipment booms. They provide high strength and rigidity and facilitate extension with exceptionally good sliding properties. This material group includes our PA 6G materials Sustamid® 6G, Sustaglide®, Lamigamid® 319 and Lamigamid® 318.
