M12
Colour:
Dark Grey
Basic Material:
PTFE
Filler:
Virgin PTFE compounded with Turcon®, mineral fibre and additives
Commercial Description:
Turcon® M12 is a modern compound and the new standard industrial material. A development of thorough benchmarking and performance testing, Turcon® M12 offers low friction, high wear resistance and costs on par with standard bronze-filled compounds. This material is designed to be the first choice for seals used with linear motion, replacing standard (medium-filled) industrial bronze-filled compounds. Used in article numbers ending in M12N and M12V.
N7
Colour:
Black
Basic Material:
NBR
Commercial Description:
A 70 durometer, NBR elastomer. The properties of the nitrile rubber depend mainly on the ACN content which ranges between 18 % and 50 %. In general it has good mechanical properties with an operating temperature range of between -30 °C and +100 °C. NBR is mostly used with mineral based oils and greases and is a good choice for standard applications. Used also as an energizer in T46N, M12N, Z20N, and Z52N.
