The unit accepts a 2-7\/16 inch bore and uses a ball bearing insert made from 52100 steel, housed in a cast iron flange body. It carries a static load capacity of 8,150 pounds and a dynamic load capacity of 11,789 pounds, making it suitable for moderate-to-heavy radial load service. The concentric collar lock secures the bearing insert to the shaft. Licensed millwrights, maintenance mechanics, and industrial technicians are the primary installers of this type of unit.\u003c\/p\u003e\n\u003cp\u003eThis flange bearing unit is used in conveyor systems, fan and blower shafts, agricultural equipment, and general industrial machinery where a rigid 4-bolt mounting point is required. The cast iron housing provides rigidity in stationary mounting applications. The VF4B 200 Series is a standard industrial frame size, and this unit is suited for both new installations and direct replacement of worn flange bearings in comparable frame configurations. Maximum shaft speed is rated at 2,500 RPM. Lubrication is required during installation and as part of routine maintenance intervals.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2-7\/16 inch bore with concentric collar lock for positive shaft engagement\u003c\/li\u003e\n  \u003cli\u003e52100 steel ball bearing insert for durability under radial load\u003c\/li\u003e\n  \u003cli\u003eCast iron housing resists deformation under static and dynamic loading\u003c\/li\u003e\n  \u003cli\u003e8,150 lb static load capacity and 11,789 lb dynamic load capacity\u003c\/li\u003e\n  \u003cli\u003e4-bolt mounting pattern with 5-5\/8 inch center-to-center bolt hole spacing\u003c\/li\u003e\n  \u003cli\u003eRated to 2,500 RPM maximum shaft speed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-install flange bearing unit for industrial shaft applications requiring a 4-bolt flange mount with a 2-7\/16 inch bore in the VF4B 200 Series frame.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by qualified millwrights or maintenance mechanics. Shut down and lock out all power to the drive system before removing or installing any bearing units, following LOTO procedures per applicable safety standards. Do not use impact tools to seat the bearing insert onto the shaft. Lubricate the bearing through the grease fitting before commissioning and maintain lubrication intervals per the equipment service schedule.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: VF4B 200\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBearing Insert Type\u003c\/strong\u003e: Ball\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: 4-Bolt Flange\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore (Inside Diameter)\u003c\/strong\u003e: 2-7\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6-7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 6-7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 5-7\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Height\u003c\/strong\u003e: 1-11\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlange Height\u003c\/strong\u003e: 13\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase-to-Center Distance\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt Hole Center-to-Center\u003c\/strong\u003e: 5-5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt Size\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStatic Load Capacity\u003c\/strong\u003e: 8,150 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDynamic Load Capacity\u003c\/strong\u003e: 11,789 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 2,500\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLock Type\u003c\/strong\u003e: Concentric Collar Lock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\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\u003eWeight\u003c\/strong\u003e: 10.8 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: 766473\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51542765830450,"sku":"766473","price":567.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d4854b51711b876a90c55e2d2b592640.jpg?v=1785906760","url":"https:\/\/voomisupply.com\/products\/browning-766473-4-bolt-flange-bearing-2-7-16-in-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
