With a maximum bore diameter of 7\/8 inches and an outer diameter of 1.88 inches, this coupling fits the 1020 coupling size code. Rated to 6000 RPM, it is suited for moderate- to high-speed drive applications in HVAC equipment, pumps, compressors, and general industrial machinery. Licensed millwrights, HVAC mechanics, and maintenance technicians are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis flexible hub coupling is used in residential and light commercial mechanical drive applications where shaft coupling flexibility is required to compensate for angular or parallel misalignment. The 1020 size code makes it a common replacement or upgrade component in belt-drive and direct-drive assemblies found in fan systems, blower assemblies, and pump drive trains. Its alloy steel construction provides durability in demanding service environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMaximum bore diameter of 7\/8 inches accommodates a range of shaft sizes up to that dimension\u003c\/li\u003e\n  \u003cli\u003eOuter diameter of 1.88 inches fits compact drive assemblies\u003c\/li\u003e\n  \u003cli\u003eRated to 6000 RPM for moderate- to high-speed applications\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for strength and wear resistance\u003c\/li\u003e\n  \u003cli\u003e1020 coupling size code for straightforward replacement identification\u003c\/li\u003e\n  \u003cli\u003eFlexible hub design reduces vibration and shock load transmission between shafts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement flexible hub coupling for mechanical drive systems requiring a 1020 size code coupling with a maximum bore of 7\/8 inches and an outer diameter of 1.88 inches.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified millwright or mechanical technician. Disconnect and lock out all power to the drive system before beginning work, following OSHA lockout\/tagout procedures. Ensure shaft diameters do not exceed the 7\/8 inch maximum bore before pressing or keying the hub onto the shaft. Do not operate the coupling above its 6000 RPM rating, and verify alignment is within the coupling's allowable tolerance after installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Size Code\u003c\/strong\u003e: 1020\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Diameter\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 1.88 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 6000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.02 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: LOVEJOY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 69790405461\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOVEJOY","offers":[{"title":"Default Title","offer_id":51542302032178,"sku":"69790405461","price":120.29,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8689ad86683e3005f4d89fed6f042995_e3e6588f-2147-4763-a78e-e0d510afb2f3.jpg?v=1785897431","url":"https:\/\/voomisupply.com\/products\/lovejoy-69790405461-flexible-hub-coupling-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
