#100-4 four-strand roller chain follows ANSI B29.1 standard with a 1.25-inch pitch, designed for ultra-heavy load power transmission scenarios. Constructed from high-quality carbon steel, its pins, rollers and link plates are processed with strict heat treatment to gain outstanding tensile strength, wear resistance and anti-fatigue property.
The four-row structure offers greater load-bearing capacity than single, double and triple strand chains, delivering steady, low-friction transmission. It is interchangeable with standard #100 sprockets for simple installation and replacement. Suitable for heavy-duty conveyors, large engineering machinery, mining equipment and high-torque drive systems, guaranteeing durable service and low maintenance costs.
