The American National Standards Institute establishes these specific configurations through the ANSI B29.1 standard. These include pitch limitations, roller size, pin diameter, and side plate thickness for universal swapping.&nbsp;&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Engineers use an ANSI standard roller chain size chart to match a chain to specific design loads and operating limits. For example, standard sizes range from a small number 25 chain up to a heavy-duty number 240 chain. A thorough ANSI standard roller chain chart lists vital attributes like average tensile strength and weight per foot.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td>Industry Number<\/td><td>Pitch (inches)<\/td><td>Roller Width (inches)<\/td><td>Roller Diameter (inches)<\/td><td>Tensile Strength (lbs)<\/td><\/tr><tr><td>25<\/td><td>0.250<\/td><td>0.125<\/td><td>0.130<\/td><td>1,036<\/td><\/tr><tr><td>35<\/td><td>0.375<\/td><td>0.188<\/td><td>0.174<\/td><td>2,469<\/td><\/tr><tr><td>40<\/td><td>0.500<\/td><td>0.312<\/td><td>0.312<\/td><td>4,188<\/td><\/tr><tr><td>50<\/td><td>0.625<\/td><td>0.375<\/td><td>0.400<\/td><td>6,834<\/td><\/tr><tr><td>60<\/td><td>0.750<\/td><td>0.500<\/td><td>0.469<\/td><td>9,259<\/td><\/tr><tr><td>80<\/td><td>1.000<\/td><td>0.625<\/td><td>0.625<\/td><td>17,636<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Material grades and heat treatment steps directly impact the total ANSI standard roller chain price. Base carbon steel variants cost less but offer minimal resistance to wet environments. Specialty alloy chains with hot-dipped lubricants or <a href=\"https:\/\/www.universalchain.net\/pt\/products\/corrosion-resistant-nickel-plated-chain\/\" data-type=\"link\" data-id=\"https:\/\/www.universalchain.net\/products\/corrosion-resistant-nickel-plated-chain\/\" target=\"_blank\" rel=\"noreferrer noopener\">nickel coatings <\/a>command premium rates because they extend wear life in harsh environments.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_to_Read_ANSI_Standard_Roller_Chain_Sizes\"><\/span><strong>How to Read <\/strong><strong>ANSI Standard Roller Chain Sizes<\/strong><strong>?&nbsp;<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">To read the sizes of the standard roller chains by ANSI, a numbering system is used through a simple code to describe structural traits.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The first digit represents the chain pitch measured in eighths of an inch. The second digit indicates the specific style, where zero means a standard roller configuration. A right-hand number five means a rollerless chain, while a number one signifies a lightweight series.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When looking at a standard <a href=\"https:\/\/www.universalchain.net\/pt\/product\/roller-chain\/\" target=\"_blank\" rel=\"noreferrer noopener\">tabela de tamanhos de correntes de rolos<\/a>, you will notice dimensions presented in both systems. A metric roller chain size chart mm converts fractional inches into exact millimeter figures.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, a standard number 40 chain features a pitch of 12.70 millimeters and a roller width of 7.92 millimeters. Maintenance crews often download an ANSI standard roller chain pdf to keep these structural metrics on hand for quick field repairs.<\/p>\n\n\n\n<style>\n.hero-product-card {\n  display: flex;\n  align-items: center;\n  justify-content: space-between;\n  background: #f9f9f9;\n  border: 1px solid #e0e0e0;\n  border-radius: 12px;\n  padding: 25px;\n  margin: 40px 0;\n  box-shadow: 0 4px 10px rgba(0,0,0,0.05);\n  font-family: Arial, sans-serif;\n  flex-wrap: wrap;\n  transition: box-shadow 0.3s ease;\n}\n\n.hero-product-card:hover {\n  box-shadow: 0 6px 16px rgba(0,0,0,0.08);\n}\n\n.hero-product-card .content {\n  max-width: 60%;\n}\n\n.hero-product-card .product-title {\n  font-size: 22px;\n  color: #cf2e2e;\n  margin-bottom: 12px;\n  font-weight: bold;\n}\n\n.hero-product-card p {\n  font-size: 15px;\n  color: #333;\n  margin-bottom: 16px;\n  line-height: 1.5;\n}\n\n.hero-product-card a.cta {\n  display: inline-block;\n  padding: 10px 18px;\n  background-color: #cf2e2e;\n  color: #fff;\n  text-decoration: none;\n  border-radius: 6px;\n  font-weight: bold;\n  transition: background-color 0.3s ease;\n}\n\n.hero-product-card a.cta:hover {\n  background-color: #af2727;\n}\n\n.hero-product-card .image {\n  max-width: 35%;\n}\n\n.hero-product-card .image img {\n  max-width: 100%;\n  border-radius: 8px;\n  border: 1px solid #ddd;\n  transition: transform 0.3s ease;\n}\n\n.hero-product-card .image a:hover img {\n  transform: scale(1.02);\n}\n\n@media (max-width: 767px) {\n  .hero-product-card .content,\n  .hero-product-card .image {\n    max-width: 100%;\n  }\n}\n<\/style>\n\n<div class=\"hero-product-card\">\n  <div class=\"content\">\n    <div class=\"product-title\">Cole\u00e7\u00e3o de Correntes de Rolos<\/div>\n    <p>Uma gama completa de correntes de rolos projetadas para transmiss\u00e3o de pot\u00eancia est\u00e1vel e eficiente em diversas aplica\u00e7\u00f5es industriais.<\/p>\n    <a class=\"cta\" href=\"https:\/\/www.universalchain.net\/pt\/roller-chain-manufacturer\/\" target=\"_blank\" rel=\"noopener\">Veja mais<\/a>\n  <\/div>\n  <div class=\"image\">\n    <a href=\"https:\/\/www.universalchain.net\/pt\/roller-chain-manufacturer\/\" target=\"_blank\" rel=\"noopener\">\n      <img decoding=\"async\" src=\"https:\/\/www.universalchain.net\/wp-content\/uploads\/2025\/08\/Industrial-Roller-Chains-1.webp\" alt=\"Conjunto de correntes de rolos para transmiss\u00e3o de pot\u00eancia industrial\">\n    <\/a>\n  <\/div>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Conclusion\"><\/span><strong>Conclus\u00e3o<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">An ANSI standard roller chain ensures exact physical compatibility across power transmission components by enforcing precise ANSI B29.1 geometry metrics.
