The main application is for conveying various packaged food products and containers.
The 821series chain is considerably stronger than the uni 820/831 chains and it is available in widths up to 304.8 mm (12.00 in.).
The link thickness is 5.0 mm (0.20 in.) the same as 831 and uni 882 series, so they can be used together with no height difference.
The links overlap, so there is no space between the links.
