Combination Chains used extensively in the cement.paper and pulp, quarrying, and mining industries for elevating and conveying a wide variety of abrasive and non-abrasive materials.It is also locating many uses generally commercial assembly conveyors. It is not recommended for drive chain.The construction of our Combination Chain can be either Transmission Chain Cottered or riveted. Cottered is generally considered regular. Pins have flat areas at their ends, which lock into the appropriately punched sidebars, preventing pin rotation during chain procedure.
All pin holes are clean-cored for simple bearing areas and are dimensioned for proper pin clearance. Industry dimensional standards are rigidly maintained and this chain could be interchanged with links of various other producers. Pitch sizes range from 1.631 to 6.050 inches; tensile power range ex1ends from 12,150 to 67,500 pounds.
All the factory’s Combination block links other than C55 and C55L have elliptical barrels. This adds extra metal where in fact the sprocket to chain contact causes many chain wear.
Attachments can be found in many of 
the pitch sizes for an array of applications.
Combination links are symmetrical and could therefore become operated in either direction of travel. Brutaloy and cast metal sprockets are available for each pitch size.
Our Promal (Duramal) chains have heat treated pins with Promal (Duramal) block links. Extremely Promal ( Duramal) chains have temperature treated pins and sidebars with Promal ( Duramal) block links.Chains are also available with prevent links of the hard Promal (Duramal).
