Combination Drive Chain 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 finding many uses generally industrial assembly conveyors. It isn’t suggested for drive chain.The construction of our Combination Chain could be either cottered or riveted. Cottered is normally considered standard. Pins have smooth areas at their ends, which lock into the properly punched sidebars, stopping pin rotation during chain procedure.
All pin holes are clean-cored for clean bearing surfaces and are dimensioned for proper pin clearance. Market dimensional standards are rigidly maintained and this chain could be interchanged with links of other manufacturers. 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 in fact the sprocket to chain contact causes most chain wear.
Attachments are available in most of 
the pitch sizes for an array of applications.
Combination links are symmetrical and may therefore be operated in either path of travel. Brutaloy and cast metal sprockets can be found for each pitch size.
Our Promal (Duramal) chains have high temperature treated pins with Promal (Duramal) prevent links. Extremely Promal ( Duramal) chains have high temperature treated pins and sidebars with Promal ( Duramal) block links.Chains are also available with block links of the hard Promal (Duramal).
