It accepts a 1-3\/16 inch inside diameter shaft and features an eccentric lock collar for positive shaft retention without keyways. The cast iron housing measures 4-1\/4 inches in overall length and 4-1\/4 inches in overall height, with a 52100 steel insert that delivers a static load capacity of 2,567 pounds and a dynamic load capacity of 4,381 pounds. This unit weighs 3.14 pounds and is well suited for conveyor systems, fan shafts, pump mounts, and general power transmission equipment installed by maintenance mechanics and millwrights.\u003c\/p\u003e\n\u003cp\u003eThe 767538 fits into applications where a rigid, 4-bolt mounted flange bearing is required on light to moderate load rotating equipment. The 3-1\/4 inch distance between mounting hole centers and 7\/16 inch bolt size align with standard mounting patterns found on industrial frames and equipment bases. Typical installations include HVAC belt-drive fan assemblies, agricultural equipment, and general industrial machinery requiring dependable shaft support at moderate speeds.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-3\/16 inch inside diameter accommodates standard fractional shafts\u003c\/li\u003e\n  \u003cli\u003eEccentric lock collar provides positive shaft retention without a keyway\u003c\/li\u003e\n  \u003cli\u003e52100 steel bearing insert rated for 2,567 pounds static and 4,381 pounds dynamic load\u003c\/li\u003e\n  \u003cli\u003eCast iron housing resists wear and handles moderate shock loads\u003c\/li\u003e\n  \u003cli\u003e4-bolt mounting pattern with 3-1\/4 inch hole center spacing and 7\/16 inch bolt size\u003c\/li\u003e\n  \u003cli\u003eCompact 4-1\/4 inch x 4-1\/4 inch overall envelope fits tight mounting footprints\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit 4-bolt flange bearing for industrial and mechanical drive applications requiring a 1-3\/16 inch bore with eccentric lock retention in a cast iron housing.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by millwrights or maintenance mechanics. Shut down and lock out all rotating equipment before removing or installing bearing units per LOTO procedures. Ensure the mounting surface is flat and the shaft is clean and free of burrs before seating the bearing. Tighten mounting bolts evenly and verify eccentric lock collar engagement before returning equipment to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBearing Type\u003c\/strong\u003e: 4-Bolt Flange\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\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\u003eFlange Height\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Height\u003c\/strong\u003e: 1-13\/64 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\u003eWidth\u003c\/strong\u003e: 2 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\u003eDistance Between Mounting Hole Centers\u003c\/strong\u003e: 3-1\/4 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\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\u003eWeight\u003c\/strong\u003e: 3.14 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: 767538\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51540607893810,"sku":"767538","price":184.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cb39f8b9e083fabdcc134aeac5bcd7d9.jpg?v=1785859926","url":"https:\/\/voomisupply.com\/products\/browning-767538-4-bolt-flange-bearing-1-3-16-in-cast-iron","provider":"Voomi Supply","version":"1.0","type":"link"}
