Combination Chain is 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 in general industrial assembly conveyors. It is not recommended 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 appropriately punched sidebars, preventing pin rotation during chain operation.
All pin holes are clean-cored for smooth bearing surfaces and are dimensioned for proper pin clearance. Industry dimensional standards are rigidly maintained and this chain may be interchanged with links of other manufacturers. Pitch sizes range from 1.631 to 6.050 inches; tensile strength range ex1ends from 12,150 to 67,500 pounds.
All our factory's Combination block links except C55 and C55L have elliptical barrels. This adds extra metal where the sprocket to chain contact causes most chain wear.
Attachments are available in many of the pitch sizes for a wide range of applications. Combination links are symmetrical and may therefore be operated in either direction of travel. Brutaloy and cast steel sprockets are available for each pitch size.
Our Promal (Duramal) chains have heat treated pins with Promal (Duramal) block links. Super Promal ( Duramal) chains have heat treated pins and sidebars with Promal ( Duramal) block links.Chains are also available with block links of the hard Promal (Duramal).
