Product description
Compact flat link chain to DIN 22255: round horizontal links with flattened vertical links, so the chain is lower in height than round link chain of the same size. It lets a face conveyor or stage loader run a stronger chain in the same pan height.
Sizes and ratings
7 sizes in 21 size and grade combinations, 26 × 92 mm to 42 × 146 mm. Minimum breaking force 850 to 2,770 kN; test force is listed for each size and grade. Every row has its own Indus part number in the table below.
Choosing a size
Listed by size and grade with test and minimum breaking force. The link dimensions are for the round horizontal link; the outside width of the flat vertical link is smaller. It is conveyor and mining machinery chain, rated by test and breaking force; it is not lifting chain and carries no working load limit.
Ordering
Quote the Indus part number from the table, or send the size and grade you need. Each consignment ships with the manufacturer's test certificate; say on the RFQ if your site needs anything more.

Size — Nominal size as the manufacturer states it. Grade — Material grade of this row — carbon and alloy versions share a frame but not a rating. Proof load — Proof or test load the manufacturer applies to the part. A test figure — never a working limit. Min breaking load — Minimum breaking load. A test figure — never lift to it. Material dia. — Diameter of the link or bar stock. Inside width — Inside width of the link or jaw. Outside width — Outside width of the link. Pitch — Thread pitch or link pitch, as the source heads it. Weight — Weight per metre, as published. Ask us for the dimension drawing if you need it stamped.
WLL is the most the part may carry in service. Proof and breaking loads are test figures — never lift to them. Each load is shown in the unit the manufacturer rates the part in, and a size ships with the manufacturer’s test certificate.
This range is published with a breaking load only, not a working load limit. Tell us the duty before using it to lift, and we will confirm a rating or recommend a rated part.
