ABOUT VSD

Special-chain manufacturing since 2011.

ANHUI VSD SPECIAL CHAIN CO., LTD. is based in the Jixi Ecological Industrial Park in Anhui, China. We manufacture engineered and heavy-duty chains for equipment builders, distributors and industrial end users.

Production follows ISO, ANSI, DIN, BS and JIS dimensional standards, with custom development for difficult geometries and demanding applications.

  • CAPACITY5,000 tonnes of chain per year
  • COMPONENTS600,000 sets per year, including locking assemblies, taper bushes and hubs
  • EXPORTNorth America, South America and Southeast Asia
  • ENGINEERINGCustom special chains developed around drawings, samples and operating duty
Certificates & qualification filesAsk our team for the current document package required for supplier qualification. We confirm the exact certificate scope for each project rather than making blanket certification claims.
