Precision manufactured to accommodate specific QD or Split-Taper bushings, depending on the tooth-count, this offers an off-the-shelf option for engineer-class sprocket types. HPE sprockets we designed and created to eliminate downtime when replacing engineer-class sprockets that are otherwise custom-bored or custom-manufactured. Additionally, these sprockets are more economical upfront than having a machine shop custom-produce a one-off sprocket.\u003c\/span\u003e\u003c\/p\u003e\n\u003cdiv class=\"btn-wrapper d-flex align-items-center\"\u003e\n\u003c!-- GET A QUOTE button and phone icon in one line --\u003e \u003ca class=\"btn-primary btn-lp-quote\" href=\"https:\/\/usarollerchain.com\/pages\/contact\"\u003e GET A QUOTE \u003c\/a\u003e \u003ca class=\"btn-lp-call d-flex align-items-center ml-3\" href=\"tel:4073473519\"\u003e \u003c!-- Smaller Phone Icon --\u003e \u003cimg style=\"width: 20px; height: 20px;\" class=\"mr-2\" alt=\"Phone Icon\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0633\/0187\/7925\/files\/phone-png-3.png?v=1751552915\"\u003e \u003cspan\u003eTalk to an expert! 407-347-3519\u003c\/span\u003e \u003c\/a\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003cstyle\u003e\ntable.vol-custom-table {\n  border-collapse: collapse;\n  width: auto;\n}\ntable.vol-custom-table th,table.vol-custom-table  td {\n  text-align: center;\n  padding: 2px;\n}\ntable.vol-custom-table th,table.vol-custom-table  td {\n  border: 2px solid #00008B;\n}\ntable.vol-custom-table tr:hover {background-color: #ecf3f8;}\n\u003c\/style\u003e\n\u003ch3\u003eHPE Sprocket Sizes\u003c\/h3\u003e\n\u003cp\u003eThe chart below shows the standard HPE sprocket sizes.
