Built from alloy steel, this hub accepts a maximum bore diameter of 1-1\/8 inches and measures 1.88 inches in outer diameter. It carries a coupling size code of 1020 and is rated for operation up to 6000 RPM. Flexible hub couplings of this type are installed by millwrights, mechanical contractors, and maintenance technicians working on pumps, compressors, fans, and similar rotating equipment.\u003c\/p\u003e\u003cp\u003eThis coupling hub is suited for industrial and commercial drive train applications where shaft-to-shaft power transmission is required. Typical installations include pump sets, conveyor drives, HVAC blower assemblies, and light industrial machinery. The alloy steel construction handles the torque and speed demands common in these environments. This is a single hub component; a complete flexible coupling assembly requires a matching hub and a flexible insert element.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMaximum bore diameter of 1-1\/8 inches accommodates a range of shaft sizes up to that dimension\u003c\/li\u003e\n\u003cli\u003eOuter diameter of 1.88 inches suits compact drive configurations\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction provides strength and durability under rotational loads\u003c\/li\u003e\n\u003cli\u003eRated to 6000 RPM for use in moderate- to high-speed drive applications\u003c\/li\u003e\n\u003cli\u003eCoupling size code 1020 for cross-referencing with standard jaw coupling series components\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style flexible hub coupling in the 1020 coupling size series, compatible with matching 1020-series hubs and flexible spider insert elements for complete jaw-style coupling assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified millwright or mechanical technician. Ensure all connected equipment is de-energized and locked out per OSHA lockout\/tagout procedures before beginning work. Shafts should be clean and free of burrs before pressing or sliding the hub into position, and set screws should be torqued per the coupling manufacturer specifications found on the product documentation. Verify shaft alignment after installation to prevent premature wear on the flexible insert element.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 1-1\/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: 0.95 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 69790405463\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOVEJOY","offers":[{"title":"Default Title","offer_id":51540438122802,"sku":"69790405463","price":120.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8689ad86683e3005f4d89fed6f042995_147260b2-c8db-4b9c-8e45-a972365304e1.jpg?v=1785855151","url":"https:\/\/voomisupply.com\/products\/lovejoy-69790405463-flexible-hub-coupling-1-1-8-in-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
