Drop forged chain sizes

Drop forged conveyor chain is sometimes referred to as en-masse conveyor chain or scraper chain. Drop forged chain is commonly fitted with special attachments that are either welded directly onto the drop forged links or alternatively bolted onto lugs that have been welded to the drop forged links. FB drop forged conveyor chains are made from specially selected high grade alloy steels. The plates are through hardened to give them their basic strength as well as make them resistant to excessive wear. The pins are case hardened, which not only makes them extremely resistant to wear, but also maintains their flexible core which results in much improved resistance to shock loading. FB drop forged chains have three main styles; standard, double and triple link.
