The unit accepts a 1-3\/16 inch bore shaft and uses a set screw lock to secure the insert to the shaft. The cast iron housing provides durability in demanding environments. Static load capacity is 2,567 pounds and dynamic load capacity is 4,381 pounds, making this unit suitable for moderate-to-heavy radial load conditions. Maximum operating speed is 4,500 RPM. Lubrication is required during installation and periodic service. Licensed HVAC, mechanical, and millwright trades install this type of bearing in fan, blower, and conveyor drive assemblies.\u003c\/p\u003e\n\u003cp\u003eThe BROWNING 767446 is used in commercial and industrial equipment where blower shafts, fan shafts, or drive line shafts require fixed-position flange mounting. The four-bolt pattern and cast iron housing suit it for both indoor mechanical rooms and light-duty outdoor installations with appropriate shielding. The 52100 steel insert provides hardness and wear resistance under continuous rotational load. This unit is appropriate for HVAC blower assemblies, air handling units, and similar rotating equipment where reliable shaft support is critical to system performance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-3\/16 inch bore accommodates standard shaft sizes in commercial HVAC and industrial fan assemblies\u003c\/li\u003e\n  \u003cli\u003e4-bolt flange mounting pattern with 3-1\/4 inch center-to-center bolt hole spacing for stable, rigid installation\u003c\/li\u003e\n  \u003cli\u003eCast iron housing resists deformation under sustained radial and axial loads\u003c\/li\u003e\n  \u003cli\u003e52100 steel bearing insert delivers high hardness and long service life under continuous rotation\u003c\/li\u003e\n  \u003cli\u003eSet screw lock secures the insert to the shaft without requiring press-fit tooling\u003c\/li\u003e\n  \u003cli\u003e4,500 RPM maximum speed rating suitable for direct-drive and belt-drive blower applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-install 4-bolt flange bearing unit for industrial and commercial rotating equipment with a 1-3\/16 inch shaft diameter requiring four-bolt flange mounting.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified millwright, HVAC mechanic, or industrial maintenance technician. Disconnect and lock out all power to the driven equipment before removing or installing the bearing unit. Ensure the shaft is clean and free of burrs before sliding the bore over the shaft and tightening set screws. This bearing requires lubrication at initial installation and at regular service intervals per the equipment manufacturer schedule.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: VF4S 200\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBearing Type\u003c\/strong\u003e: Ball Bearing Insert\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Type\u003c\/strong\u003e: 4-Bolt Flange\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Bore)\u003c\/strong\u003e: 1-3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 4-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1-9\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 3-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt Hole Center-to-Center\u003c\/strong\u003e: 3-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt Size\u003c\/strong\u003e: 7\/16 inches\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\u003eBase Height\u003c\/strong\u003e: 1-5\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlange Height\u003c\/strong\u003e: 17\/32 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\u003eLock Type\u003c\/strong\u003e: Set Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHousing Material\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: 52100 Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLubrication\u003c\/strong\u003e: Required\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.76 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: 767446\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51542055944498,"sku":"767446","price":176.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d82f5e1b33e522fd8b919b51c590ab36.jpg?v=1785890717","url":"https:\/\/voomisupply.com\/products\/browning-767446-4-bolt-flange-bearing-1-3-16-in-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
