Characteristics and performance

The Type 540 material is used in Dynamic Seals’ precision bearing rings, both the heavy wall machined bearings used as replacements for bronze, cast iron, powered metal and phenolic materials where compression strength and low moisture absorption are key requirements, and as thinner wall parts where tighter tolerances and dimensions stability in an as-molded part are of paramount importance.

Product details

The Type 540 material is a general purpose heat stabilized, lubricated, type 66 nylon reinforced with 40% mineral that encompasses a high aspect ration particle shape.
