Help With Identifying the Right Chain Solution
Donghua Limited , the UK arm of one of the world ’ s largest chain manufacturers , has recategorised its extensive Drive Chain products into three ranges to help make it easier for customers to identify the right chain solution . The three new ranges are : Standard , Solution and Premium .
The Standard Range features a variety of standard chain manufactured with precision to suit simple drives with large diameter sprockets or complex drives with multiple sprockets and high load bearings .
The new Premium Range offers customers ultimate solution to problems with chain wear , chain fatigue , high speed , lubrication , chain length accuracy and chain strength offering optimum performance in extreme conditions . A new Premium Range chain is being launched in the UK later this year .
The Solution Range offers our customers a genuine solution to problems with chain wear , chain fatigue , corrosion , high speed , lubrication , chain length accuracy and chain strength with specific build features designed to enhance durability and withstand a range of arduous environments .
Our new Solution Range incorporates Donghua ’ s existing HSP Chain , SLR Chain and CP Chain plus our recently launched EXL Chain .
HSP Chain : Donghua ’ s Heavy Super Power ( HSP ) Chain is specifically designed for aggressive environments and has become a highly popular chain in the UK . HSP Chain is suited to agricultural and industrial applications and boasts ultimate tensile strength up to 50 per cent higher than DIN standard chains . HSP Chain has wide-waist plates to give extreme fatigue strength and high interference fit between pins and plates .
SLR Chain : Donghua ’ s Self-Lubricating Roller ( SLR ) Chain incorporates special oil impregnated sintered bushings which extend beyond the inner plates to prevent dirt ingress , giving these chains their self-lubricating characteristics .
Nickel plated throughout to prevent corrosion , and with chemically plated and tempered pins , SLR Chain offers improved wear resistance and added protection in the bearing area . This chain is ideal for use in areas where chain lubrication is difficult or undesirable .
CP Chain : Donghua ’ s Chromized Pin ( CP ) Chain offers increased wear life over standard roller chain . It is designed with a chromized pin ; adding a chrome surface coating to the pins results in super-hard pins which extends the wear life of the chain . With a 1100 HV10 surface hardness , CP Chain is ideal for dirty / dusty conditions , giving high abrasion resistance .
EXL Chain : Recently launched in the UK , the premium 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 EXL Chain to be cut in the field using Donghua ’ s Plate Extractor tools .

NEW CHAIN SELECTION CHART To help UK customers select the correct chain solution , we have developed a simple reference guide – the Donghua Chain Selection Chart . The chart provides a visual 1 - 5 star rating highlighting our recommendations for each chain product for wear resistance , fatigue resistance , strength , shock load , corrosion resistance , selflubrication , easy break , FDA approved and so on . It ’ s a must-have reference document in an engineer ’ s toolkit .
