Commonly found in forklifts, telehandlers, and warehouse equipment, they are valued for their strength and simplicity. Also known as balance chains or cable chains, leaf chains resemble roller chains in shape but are optimized for vertical load transmission.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Leaf Chain vs. Roller Chain: What&#8217;s the Difference?<\/strong><\/h2>\n\n\n\n<figure class=\"wp-block-image size-large\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"512\" src=\"https:\/\/mccchains.com\/wp-content\/uploads\/2022\/09\/Leaf-Chain-1024x512.jpg\" alt=\"\" class=\"wp-image-4728\"\/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Leaf chains and roller chains may look similar at first glance, but they serve very different purposes due to their structural differences. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Roller chains include pins, bushings, and rollers, allowing them to run smoothly over sprockets\u2014making them ideal for industrial machinery. In contrast, leaf chains are made only of plates and pins, designed to run over sheaves. This simpler construction makes them perfect for forklifts, telehandlers, and other material handling equipment.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th class=\"has-text-align-center\" data-align=\"center\"><strong>Chain<\/strong><\/th><th><strong>Plate<\/strong><\/th><th class=\"has-text-align-center\" data-align=\"center\"><strong>Pin<\/strong><\/th><th class=\"has-text-align-center\" data-align=\"center\"><strong>Bush<\/strong><\/th><th class=\"has-text-align-center\" data-align=\"center\"><strong>Roller<\/strong><\/th><th class=\"has-text-align-center\" data-align=\"center\">Runs On<\/th><th><strong>Applications<\/strong><\/th><\/tr><\/thead><tbody><tr><td class=\"has-text-align-center\" data-align=\"center\"><strong>Roller Chain<\/strong><\/td><td>1.
