Metric Trough Scraper Chains
This series has developed in the US grain industry as an alternative to Welded steel chain in high capacity grain handling equipment. The chain construction is as Precision PCB style with a pressed bush and pin. The link plates maintain the crank link form. There are five main standards within the series which loosely follow the Welded steel range. Other varieties can be offered (request details of Precision works standard MX series chains). The flight formats will be as welded steel chain (P21) with polyethylene flights in various forms bolted to steel backing plates which in turn are welded to the chain.
