Built to ANSI standards, this sprocket features a 3.72-inch outside diameter, 17 teeth, and a 0.625-inch pitch compatible with Size 50 roller chain. Constructed from steel, it delivers reliable durability in industrial and mechanical drive applications. This is a passive idler component, meaning it does not transmit torque but instead controls chain path and slack. Technicians and maintenance professionals working on conveyor systems, mechanical drives, and automated equipment will find this a direct-spec replacement.\u003c\/p\u003e\u003cp\u003eThis sprocket is suited for single-strand Size 50 roller chain applications in light to medium industrial drive systems. Typical install scenarios include conveyor lines, packaging equipment, agricultural machinery, and general mechanical power transmission assemblies where a tensioning or guiding sprocket is required. The ANSI-standard design ensures dimensional conformance across compatible chain and sprocket assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSize 50 single-strand roller chain compatibility per ANSI standards\u003c\/li\u003e\n\u003cli\u003e17-tooth count with 0.625-inch pitch for precise chain engagement\u003c\/li\u003e\n\u003cli\u003e3.72-inch outside diameter for defined chain path geometry\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability in industrial environments\u003c\/li\u003e\n\u003cli\u003eIdler configuration maintains chain tension without transmitting drive torque\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with ANSI Size 50 single-strand roller chain in standard power transmission drive assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified maintenance technician or millwright. De-energize and lock out the drive system before beginning any sprocket service or chain work, following applicable LOTO procedures. Ensure the idler is properly aligned with the drive and driven sprockets to prevent premature chain wear. Do not overtighten the chain when setting idler position, as proper slack allowance is required per the drive manufacturer guidelines.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eChain Trade Size\u003c\/strong\u003e: 50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Teeth\u003c\/strong\u003e: 17\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Strands\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3.72 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31171900\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: BROWNING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1297274\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51541931655474,"sku":"1297274","price":186.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/780a373a35850ac68e3f6b495811cfd0.jpg?v=1785887927","url":"https:\/\/voomisupply.com\/products\/browning-1297274-chain-idler-sprocket-size-50-17t-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
