Help Selecting The Right Chain Solution

To help customers select the right chain solution, Donghua Limited has developed a simple tool – the Donghua Chain Selection Chart.

Donghua Limited is the UK arm of one of the world’s largest chain manufacturers who produce over 40 million metres of finished chain per year which is supplied world-wide. Our UK operation is based in Wolverhampton, West Midlands where our sales office, 25,000 sq ft warehouse, technical laboratory and chain workshop are located.

Our Chain Selection Chart is a reference guide specifically created for our growing network of Approved Product Partners and Stockists. It provides a visual 1-5 star rating highlighting Donghua Chain recommendations for:

  • wear resistance
  • fatigue resistance
  • high speed
  • strength
  • shock load
  • high strength/high shock
  • corrosion resistance
  • self-lubricating
  • easy break
  • FDA approved
  • damp/wet environment
  • general purpose
  • high temperature

It’s a must-have reference document in an engineer’s toolkit.

The Chain Selection Chart includes our new EXL and X3 Roller Chain.

EXL Chain

EXL Chain offers significant benefits over standard Roller Chain. It utilises different materials, material treatments and layer technologies, to offer the best possible quality/price ratio for all applications.

Aimed specifically for the after-market, EXL Chain is designed, manufactured and tested for unbeatable accuracy and performance in arduous conditions, offering enhanced wear and fatigue resistance and greater precision.

The chain is designed with a new hardened, shot-peened wide-waist plate for increased fatigue strength and a seamless cold forged solid bush and roller to give full contact between the pin, bushing and roller for higher durability.

The EXL Chain has optimised cylindrical parts which improve sliding contacts to help increase service life. It also incorporates Donghua’s unique ‘Easy Break Technology’ which enables the Chain to be cut in the field using Donghua’s Plate Extractor tools.

X3 Chain

X3 Chain, which was launched earlier this year, is manufactured on its own purpose-built production line which encompasses new production techniques and new surface treatments.

Designed with a unique pin coating, optimised plate geometry and high precision stamping, X3 offers a new deluxe chain solution and is designed for sectors that use high demand drives such as Timber, Waste & Recycling and Mining & Quarrying.

The new X3 Chain delivers three times the performance for wear resistance, fatigue resistance and high speed performance for comparable Roller Chain.  Its superior quality, durability and outstanding wear and fatigue resistance are realised by the new hardened, shot-blasted plate shape, calibrated pin and bushing holes, special heat-treated and surface coated pins, seamless rollers and bushings and high performance pre-lubrication.

Our X3 Chain is supplied pre-loaded and pre-lubricated as standard and is available in British Standard 06B to 24B in simplex and duplex, ex-stock.
