Duratron®T4301 Bearing Grade PAI

Duratron® T4301 PAI AE (aerospace) offers a very low expansion rate and coefficient of friction, and also exhibits little to no slip-stick in use. The addition of PTFE and graphite provides higher wear resistance compared to the unfilled Duratron® T4203 PAI grade, and also gives Duratron® T4301 PAI AE excellent dimensional stability capabilities over a wide temperature range. Duratron® T4301 PAI AE's flexural modulus of elasticity is higher than most other advanced engineering plastics, which allows it to excel in severe service wear applications in aerospace engineering such as non-lubricated bearings, seals, bearing cages, and reciprocating compressor parts.

Limitations

Duratron® T PAI Grade Materials have a relatively high moisture absorption rate, parts used in high temperature service or made to tight tolerances should be kept dry prior to installation.

Thermal shock resulting in deformation can occur if moisture laden parts are rapidly exposed to temperatures above 400°F (205° C).

Chemical Resistance to Strong Bases, Steam and Some High Temperature Acids
