Nickel Plated (NP)
roller chains
NP “Nickel Plated” roller chains are produced with
the same specifications as the KW standard roller
chains. In addition to that, all components receive
a nickel plating.
The coating has a complementary copper plating
base layer for significantly higher corrosion protection
properties than standard nickel coatings.
Furthermore, the nickel-plated roller chains are
free of chromium-6 components and hydrogen
embrittlement.
Nickel-plated chains can also be supplied with FDA
class H1 or FDA class H2 compliant lubrication upon
request.
