With a maximum bore diameter of 1-7\/16 inches and an overall length of 4-5\/8 inches, this unit provides a rigid, bolt-down mounting solution for rotating shaft assemblies. The cast iron housing delivers durability under load and resists deformation in demanding service environments. Installation is handled by maintenance technicians and millwrights working on conveyor systems, blower assemblies, and similar equipment requiring reliable shaft support.\u003c\/p\u003e\u003cp\u003eThis bearing is suited for use in light-to-medium industrial applications where a 4-bolt flange mount is required for positive housing retention. The 3-1\/2 inch distance between mounting hole centers and 1\/2 inch bolt size allow straightforward alignment to standard bolt patterns on equipment frames and mounting plates. The tapered roller design accommodates combined radial and axial loads. Typical install scenarios include conveyor drive shafts, fan shaft assemblies, and general power transmission equipment in commercial and industrial facilities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType E 4-bolt flange configuration for positive, rigid shaft mounting\u003c\/li\u003e\n\u003cli\u003eMaximum bore diameter of 1-7\/16 inches accommodates common shaft sizes\u003c\/li\u003e\n\u003cli\u003eCast iron housing provides strength and resistance to deformation under load\u003c\/li\u003e\n\u003cli\u003e3-1\/2 inch center-to-center mounting hole spacing for standard bolt pattern alignment\u003c\/li\u003e\n\u003cli\u003e1\/2 inch bolt size for secure fastening to equipment frames\u003c\/li\u003e\n\u003cli\u003eOverall length of 4-5\/8 inches with a width of 3-5\/64 inches for compact envelope fit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-mount flange bearing for industrial shaft assemblies requiring a Type E 4-bolt flange configuration with a 1-7\/16 inch bore.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a qualified millwright or maintenance technician. Shut down and lock out all power to the equipment before removing or installing the bearing assembly. Ensure the mounting surface is flat and clean, and verify shaft diameter and bolt pattern dimensions before mounting. Do not over-torque the mounting bolts; follow the equipment manufacturer fastener specifications for proper clamping force.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBearing Type\u003c\/strong\u003e: Type E 4-Bolt Flange Bearing, Mounted Tapered Roller\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Diameter\u003c\/strong\u003e: 1-7\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3-5\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDistance Between Mounting Hole Centers\u003c\/strong\u003e: 3-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt Size\u003c\/strong\u003e: 1\/2 inch\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: 6.9 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31171500\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 730021\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51539533234482,"sku":"730021","price":361.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/065f6cd661b3c900426b7bad535aea55_cc564ab8-b1c7-4290-b679-accc7e55df8e.jpg?v=1785842524","url":"https:\/\/voomisupply.com\/products\/browning-730021-type-e-4-bolt-flange-bearing-1-7-16-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
