U.S. TSUBAKI LEAF CHAINA - DRIVE CHAINS<strong>Leaf</strong> <strong>Chain</strong><strong>Leaf</strong> chains generally have greater tensile strength thanroller chains, and run over sheaves rather than sprockets.They are most often used as counterweight chains formachine tools, elevator and oven doors, fork lift truck masts,spinning frames and similar lifting or balancing applications.BL series can, in most instances, replace the older AL series<strong>Leaf</strong> chains; consult U.S. Tsubaki for interchangeinformation.These chains are supplied with male or female terminationsto allow addition of various clevises as desired.A-63

A - DRIVE CHAINSGENERAL CAUTIONS1. Use lengths of factory assembled chain. Do not build lengths from individual components.2. Do not attempt to rework damaged chains by replacing only the components obviouslyfaulty. The entire chain may be compromised and should be discarded.3. Never electroplate assembled <strong>Leaf</strong> chain or its components. Plating could result in failurefrom hydrogen embrittlement.4. Welding should not be performed on any chain or component. Welding spatter should neverbe allowed to come in contact with chain or components.5. <strong>Leaf</strong> chains are manufactured exclusively from heat treated steels and, therefore, must notbe annealed. If heating a chain with a cutting torch is absolutely necessary for removal, thechain should not be reused.6. Joining chains together should only be done by the chain manufacturer.7. The Minimum Ultimate Strength of a chain means the minimum load at which it will breakwhen subjected to a destructive tensile test. It does not mean working load.8. <strong>Chain</strong>s from different manufacturers should not be used in the same application.A-68
