It features a 1-1\/4 inch inside diameter bore with a set screw locking mechanism to secure the shaft. The bearing insert is made from 52100 steel, a high-carbon chromium alloy commonly used for rolling element bearings. With a static load capacity of 3,493 pounds and a dynamic load capacity of 5,782 pounds, this unit is built for sustained radial loading in fan and blower assemblies. HVAC technicians and mechanical contractors install this bearing as part of belt-driven air handler and fan coil shaft support configurations.\u003c\/p\u003e\n\u003cp\u003eThis pillow block is suited for residential and light commercial air handling equipment where shaft support and alignment are critical to fan performance. Typical installations include belt-drive blower assemblies, centrifugal fan shafts, and similar rotating equipment inside air handlers and rooftop units. The 5-inch distance between mounting hole centers and the 1-7\/8 inch base-to-center height make it compatible with standard mounting plates and fan decks commonly found in these systems. The overall assembly measures 6-3\/4 inches in overall length and 3-11\/16 inches in overall height.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/4 inch inside diameter bore for standard shaft sizing in blower and fan applications\u003c\/li\u003e\n  \u003cli\u003eSet screw locking mechanism secures the shaft without requiring a keyway\u003c\/li\u003e\n  \u003cli\u003e52100 steel bearing insert provides high load capacity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eCast iron housing for durability in commercial and light industrial environments\u003c\/li\u003e\n  \u003cli\u003e3,493 pound static load capacity and 5,782 pound dynamic load capacity\u003c\/li\u003e\n  \u003cli\u003e5-inch mounting hole center distance simplifies drop-in replacement on standard fan decks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement pillow block bearing for air handling and HVAC fan shaft applications requiring a 1-1\/4 inch bore with set screw locking and cast iron housing construction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed HVAC technician or millwright. Disconnect and lock out all electrical power to the air handler before servicing any rotating components. Ensure the mounting surface is flat and the bearing housing is torqued evenly to prevent housing distortion. Verify shaft diameter and alignment before tightening set screws, and re-check alignment after the first operational run.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 3-11\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBearing Width\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBearing Length\u003c\/strong\u003e: 1-9\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDistance Between Mounting Hole Centers\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase to Center Height\u003c\/strong\u003e: 1-7\/8 inches (1.688 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlange Height\u003c\/strong\u003e: 7\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStatic Load Capacity\u003c\/strong\u003e: 3,493 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDynamic Load Capacity\u003c\/strong\u003e: 5,782 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLock Type\u003c\/strong\u003e: Set Screw\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\u003eWeight\u003c\/strong\u003e: 3.66 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: 765810\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BROWNING","offers":[{"title":"Default Title","offer_id":51541631861042,"sku":"765810","price":213.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0f4eb343c8c53bb18b4a1236bb227098.jpg?v=1785880784","url":"https:\/\/voomisupply.com\/products\/browning-765810-pillow-block-bearing-1-1-4-in-air-handling","provider":"Voomi Supply","version":"1.0","type":"link"}
