The unit accepts a 1 inch shaft with a set screw lock and houses a ball bearing insert made from 52100 steel. It carries a static load capacity of 2,567 pounds and a dynamic load capacity of 4,381 pounds. The cast iron housing provides durability in demanding environments. Maximum operating speed is 4,500 RPM. Licensed millwrights, maintenance technicians, and industrial mechanics are the typical installers of this unit.\u003c\/p\u003e\n\u003cp\u003eThis flange bearing is suited for light-to-medium industrial equipment including conveyors, fans, pumps, and material handling systems where a 4-bolt flange mount is required. The VF4S 300 Series is designed for installations where the bearing must be secured to a flat mounting surface with four bolts at a center-to-center distance of 3.25 inches. The overall length and height are each 4.25 inches, making it a compact, square-footprint unit appropriate for space-constrained equipment frames. Lubrication is required and must be maintained per the equipment service schedule.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1 inch inside diameter with set screw shaft lock for positive retention\u003c\/li\u003e\n  \u003cli\u003eBall bearing insert manufactured from 52100 steel for load durability\u003c\/li\u003e\n  \u003cli\u003eStatic load capacity of 2,567 pounds and dynamic load capacity of 4,381 pounds\u003c\/li\u003e\n  \u003cli\u003eCast iron housing rated for demanding industrial environments\u003c\/li\u003e\n  \u003cli\u003eMaximum speed rating of 4,500 RPM\u003c\/li\u003e\n  \u003cli\u003e4-bolt mounting pattern with 3.25 inch bolt hole center-to-center spacing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit unit for industrial equipment accepting a 4-bolt flange bearing with a 1 inch bore in the VF4S 300 Series configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed millwrights or qualified maintenance technicians. De-energize and lock out all power to the equipment before removing the existing bearing or mounting the new unit. Verify shaft diameter and confirm bolt hole pattern matches the mounting surface before installation. Lubrication is required at initial installation and at regular service intervals — use the grease type and interval specified by the equipment manufacturer.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 4.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.5625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStatic Load Capacity\u003c\/strong\u003e: 2,567 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDynamic Load Capacity\u003c\/strong\u003e: 4,381 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 4,500\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt Hole Center-to-Center\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt Size\u003c\/strong\u003e: 7\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase-to-Center Distance\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlange Height\u003c\/strong\u003e: 0.53125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Height\u003c\/strong\u003e: 1.078 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 3.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLock Type\u003c\/strong\u003e: Set Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBearing Insert Type\u003c\/strong\u003e: Ball\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: 52100 Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHousing Material\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLubrication\u003c\/strong\u003e: Required\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: VF4S 300\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.86 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31171500\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 767904\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51538938036530,"sku":"767904","price":139.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/39a0083cecb01e6ffdeeef132214e64b.jpg?v=1785830241","url":"https:\/\/voomisupply.com\/products\/browning-767904-4-bolt-flange-bearing-1-inch-id-cast-iron","provider":"Voomi Supply","version":"1.0","type":"link"}
