Torlon PAI-4301

Polyamide-imide, Adding Teflon and graphite, bearing grade

Product Description:


The addition of graphite and PTFE provides higher wear resistance and lower coefficient of friction compared to the unfilled grade as well as little or no stick-slip in use. This grade excels in severe wear applications such as non-lubricated bearings, seals, bearings cages and reciprocating compressor parts.
