Combination Chains used extensively in the cement.paper and pulp, quarrying, and mining industries for elevating and conveying a wide variety of abrasive and nonabrasive materials.It is also obtaining many uses in general industrial assembly conveyors. It isn’t suggested for drive chain.The construction of our Combination Chain can be either cottered or riveted. Cottered is normally considered standard. Pins have flat areas at their ends, which lock into the properly punched sidebars, avoiding pin rotation during chain operation.
All pin holes are clean-cored for even bearing areas and so are dimensioned for proper pin clearance. Industry dimensional Drive Chain criteria are rigidly preserved and this chain may 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 our factory’s Combination block links other than C55 and C55L have elliptical barrels. This provides extra metal where the sprocket to chain contact causes most chain wear.
Attachments can be found in many of the pitch sizes for a wide range of applications.
Combination links are symmetrical and could therefore be operated in either direction of travel. Brutaloy and cast steel sprockets are available for every pitch size.
Our Promal (Duramal) chains have high temperature treated pins with Promal (Duramal) block links. Super 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).
