Narrow Series Welded Steel Chain
Our narrow series welded steel chain refers to the welded offset sidebar chain with relatively narrower inner width. To illustrate, on this page, we mainly show you our products with narrow-end inner width from 28mm to 77.1mm, and outer width from 51mm-117.35mm.
This series welded chain is especially designed for conveying of abrasive materia EPT under the operating environment with strong impact or heavy dust. It is commonly used as scraper conveyor chain for the conveying for grains, bean pulp, industrial bulk cargo, etc. The welded steel chain is also applicable for wood processing industry.
