About #240H-3 Heavy Duty Roller Chain
ANSI‑standard triple‑strand heavy‑duty roller chain is manufactured from high‑grade alloy steel and treated with precise heat‑treatment. Reinforced thicker link plates greatly boost breaking strength, wear resistance and impact resistance. Its three‑row structure provides outstanding load‑bearing capacity for harsh, high‑torque working environments. Ideal for mining equipment, heavy‑duty conveyors, construction machinery and large‑scale industrial drives. Various surface finishes are optional, and customized solutions are offered to satisfy diverse application demands.
