It accepts a 1-11\/16 inch shaft and provides a static load capacity of 5,139 pounds and a dynamic load capacity of 7,901 pounds, making it well suited for heavy radial load service. The housing is cast iron for rigidity and durability. The eccentric locking collar secures the bearing insert to the shaft without set-screw damage to the shaft surface. Licensed millwrights, maintenance mechanics, and industrial service technicians typically install this type of unit in fan, conveyor, pump, and blower shaft assemblies.\u003c\/p\u003e\n\u003cp\u003eThis flange bearing is used in residential and commercial mechanical systems where a 4-bolt mounting pattern is required. Common applications include HVAC fan shaft supports, industrial blower assemblies, conveyor drive systems, and pump mounting stations. The 4-1\/8 inch distance between mounting hole centers aligns with standard bolt patterns found in most OEM equipment frames. The 5-3\/8 inch overall length and 5-3\/8 inch overall height allow installation in standard flange-mount cavities without modification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-11\/16 inch bore ID accepts a standard shaft diameter with eccentric collar locking\u003c\/li\u003e\n  \u003cli\u003e5,139 pound static load capacity and 7,901 pound dynamic load capacity for heavy radial service\u003c\/li\u003e\n  \u003cli\u003eCast iron housing resists deflection and provides stable mounting in demanding environments\u003c\/li\u003e\n  \u003cli\u003e52100 steel bearing insert for high hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003e4-bolt mounting pattern with 9\/16 inch bolt size and 4-1\/8 inch center-to-center spacing\u003c\/li\u003e\n  \u003cli\u003eEccentric lock design minimizes shaft marring during installation and removal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or upgrade flange bearing for industrial and commercial shaft assemblies requiring a 1-11\/16 inch bore, 4-bolt cast iron flange unit with eccentric locking collar.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified millwright or maintenance mechanic. De-energize and lock out all power to the driven equipment before removing or installing the bearing unit. Ensure the mounting surface is flat and clean before torquing the four mounting bolts evenly in a cross pattern. Verify shaft alignment before final tightening of the eccentric locking collar to prevent premature bearing wear.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1-11\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 5-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStatic Load Capacity\u003c\/strong\u003e: 5,139 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDynamic Load Capacity\u003c\/strong\u003e: 7,901 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDistance Between Mounting Hole Centers\u003c\/strong\u003e: 4-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBolt Size\u003c\/strong\u003e: 9\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2-9\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlange Height\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Height\u003c\/strong\u003e: 1-21\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 4-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLock Type\u003c\/strong\u003e: Eccentric 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\u003eUnit Weight\u003c\/strong\u003e: 5.58 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: 767873\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51538735300914,"sku":"767873","price":336.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dbf01ba179539046e7cc56710529b544_b5e606d1-cc35-407a-931e-b6cffcc24e44.jpg?v=1785825879","url":"https:\/\/voomisupply.com\/products\/browning-767873-4-bolt-flange-bearing-1-11-16-in-cast-iron","provider":"Voomi Supply","version":"1.0","type":"link"}
