RK Chains

RK_TAKASAGO_header_en
… perfect quality and performance.

All RK Sealed chains feature heat treated
hi-carbon alloy steel components,
giving unrivalled wear life. Seamless rollers that
allow the chain to run freely between the teeth
of the sprocket and reduce chain vibration and
shouldered bushings allow the patented XW seal
to retain 72% more lubricant than an old timer
O-ring seal. All RK seals are made from an advanced
Nitrile Butadiene composite for maximum performance
and wear life. All RK sealed-ring Chains come with RK’s
exclusive 20,000 mile warranty.
