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 finding many uses in general industrial assembly conveyors. It is not suggested for drive chain.The Leaf Chain construction of our Combination Chain could be either cottered or riveted. Cottered is generally considered standard. Pins have flat areas at their ends, which lock in to the properly punched sidebars, avoiding pin rotation during chain operation.
All pin holes are clean-cored for clean bearing surfaces and are dimensioned for proper pin clearance. Market dimensional specifications are rigidly taken care of and this chain may 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 the factory’s Combination block links other than C55 and C55L have elliptical barrels. This provides extra metal where in fact the sprocket to chain get in touch with causes most chain wear.
Attachments are available 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 steel sprockets can be found for each pitch size.
Our Promal (Duramal) chains have heat treated pins with Promal (Duramal) prevent links. Super Promal ( Duramal) chains have warmth treated pins and sidebars with Promal ( Duramal) block links.Chains are also available with block links of the hard Promal (Duramal).
