It combines a ball bearing insert made from 52100 steel with a cast iron housing, delivering a static load capacity of 1,651 pounds and a dynamic load capacity of 2,801 pounds. The bore measures 1 inch in diameter with an overall length of 4-7\/8 inches and an overall height of 2-3\/4 inches. A concentric collar lock secures the bearing insert to the shaft. Licensed HVAC, mechanical, and industrial technicians install this unit in belt-driven and shaft-driven equipment where secure, low-maintenance flange mounting is required.\u003c\/p\u003e\n\u003cp\u003eThe 766957 is suited for light-to-medium duty shaft support in residential and commercial mechanical systems, including HVAC fan assemblies, conveyor drives, blower shafts, and agricultural or industrial equipment. The 2-bolt mounting pattern simplifies installation on standard mounting plates and frames. With a maximum operating speed of 5,500 RPM and a base-to-center distance of 0.875 inches, this unit fits a wide range of standard shaft-driven configurations. Lubrication is required for proper operation and service life.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1 inch bore with concentric collar lock for positive shaft retention\u003c\/li\u003e\n  \u003cli\u003eStatic load capacity of 1,651 pounds and dynamic load capacity of 2,801 pounds\u003c\/li\u003e\n  \u003cli\u003eMaximum rated speed of 5,500 RPM\u003c\/li\u003e\n  \u003cli\u003eCast iron housing for durability in industrial environments\u003c\/li\u003e\n  \u003cli\u003e52100 steel bearing insert for wear resistance\u003c\/li\u003e\n  \u003cli\u003e2-bolt flange mount with 3-57\/64 inch center-to-center bolt hole 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 flange bearing for shaft assemblies requiring a 1 inch bore 2-bolt flange unit within the VF2B 200 Series specification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed mechanical or HVAC technicians. Shut down and lock out the drive system before removing or installing the bearing unit per applicable OSHA lockout\/tagout procedures. Secure the housing bolts evenly using appropriately sized fasteners through the 7\/16 inch bolt holes. This bearing requires periodic lubrication after installation — consult the manufacturer service schedule for lubrication intervals and approved grease types.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: VF2B 200\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: 2-Bolt Flange\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBearing Insert Type\u003c\/strong\u003e: Ball\u003c\/li\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: 4-7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 2-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBearing Length\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt Hole Center-to-Center\u003c\/strong\u003e: 3-57\/64 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: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Height\u003c\/strong\u003e: 61\/64 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStatic Load Capacity\u003c\/strong\u003e: 1,651 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDynamic Load Capacity\u003c\/strong\u003e: 2,801 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 5,500\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLock Type\u003c\/strong\u003e: Concentric Collar Lock\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: 1.3 pounds\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: 766957\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51539979829554,"sku":"766957","price":209.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f89d721274229bc1fe8e562dd9c77311.jpg?v=1785845288","url":"https:\/\/voomisupply.com\/products\/browning-766957-2-bolt-flange-bearing-1-inch-id-cast-iron","provider":"Voomi Supply","version":"1.0","type":"link"}
