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 locating many uses in general industrial assembly conveyors. It isn't suggested for drive chain.The construction of our Combination Chain could be either cottered or riveted. Cottered is generally considered regular. Pins have toned areas at their ends, which lock into the properly punched sidebars, stopping pin rotation during chain procedure.
All pin holes are clean-cored for soft bearing surfaces and are dimensioned for proper pin clearance. Market dimensional criteria are rigidly managed which chain may be interchanged with 
links of various other manufacturers. Pitch sizes range between 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 possess elliptical barrels. This adds extra metal where the sprocket to chain contact causes the majority of chain wear.
Attachments are available in many of the pitch sizes for a wide selection of applications.
Combination links are symmetrical and could therefore be operated in either Stainless Steel Chain direction of travel. Brutaloy and cast steel sprockets can be found for every 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) prevent links.Chains are also available with prevent links of the hard Promal (Duramal).
