Combination Chains used extensively in the cement.paper and pulp, quarrying, and mining industries for elevating and conveying a multitude of abrasive and nonabrasive materials.It is also acquiring many uses in general commercial assembly conveyors. It is not suggested for drive chain.The construction of our Combination Chain could be either cottered or riveted. Cottered is generally considered standard. Pins have smooth areas at their ends, which lock in to the properly punched sidebars, preventing pin rotation during chain procedure.
All pin holes are clean-cored for even bearing surfaces and are dimensioned for proper pin clearance. Industry dimensional specifications are rigidly taken care of and this chain may be interchanged with links of other producers. Pitch sizes range from 1.631 to 6.050 inches; tensile power range ex1ends from 12,150 to 67,500 pounds.
All our factory’s Combination block links other than C55 and C55L possess elliptical barrels. This adds extra metal where the sprocket to chain contact causes many chain 
wear.
Attachments can be found in most 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 every pitch size.
Our Promal (Duramal) chains have warmth treated pins with Promal (Duramal) prevent links. Extremely Promal ( Duramal) chains have high temperature treated pins and sidebars with Promal ( Duramal) prevent links.Chains are also available with block links of the hard Promal (Duramal).
