EK Chain is headquartered in Kaga, Japan. In 1974 EK introduced the world’s first sealed O-ring chain. Quality is an obsession at EK Chain. Research and development has always focused on creating technological breakthroughs and developing original ideas. EK’s invention of the O-ring sealed chain was based on years of accumulated technology, exemplifying a relentless commitment to innovation that continues to drive everything they do.
CRH PIN TREATMENT: RIGID & LONG LIFE! EK’s exclusive CRH pin treatment provides an extremely hard outside coating and softer inside to increase strength and reduce chain wear. The Chromium Carbide pin surface coating also offers superior impact and shock absorption while reducing oxidation caused by nature’s elements.
SCREW TYPE MASTER LINK (SLJ:) EK’s screw type master links do not require any special tools for installation. This unique patented link gives a rivet-like fit, using only an 8mm wrench and a pair of pliers.
LIGHTENING HOLES: Lightening holes on the side plat reduce the chain’s overall weight by 3%, without compromising tensile strength. These holes extend the service life by dissipating heat & helping reduce dirt and mud build-up.
