With a maximum bore diameter of 1-5\/8 inches and an outer diameter of 4-1\/2 inches, this coupling accommodates shaft connections where minor misalignment, vibration damping, or torque shock absorption is required. The overall assembled length is 4.88 inches and the unit is constructed from sintered iron, providing good wear resistance and structural integrity at operating speeds up to 5000 RPM. Licensed millwrights, mechanical contractors, and pump system technicians typically install and service this type of coupling.\u003c\/p\u003e\n\u003cp\u003eThis flexible hub coupling is suited for use in a range of rotating equipment setups including pumps, compressors, blowers, and light industrial drive trains. The sintered iron construction makes it appropriate for indoor mechanical rooms and equipment pads where lubrication or grease retention is beneficial. It is sold individually and sized under the L190 coupling size code, making it straightforward to match with corresponding spider elements and mating hubs of the same series when replacing worn components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMaximum bore diameter of 1-5\/8 inches for compatibility with common shaft sizes\u003c\/li\u003e\n  \u003cli\u003e4-1\/2 inch outer diameter for L190-series coupling applications\u003c\/li\u003e\n  \u003cli\u003e4.88 inch overall length provides adequate hub engagement depth\u003c\/li\u003e\n  \u003cli\u003eSintered iron construction offers wear resistance and dimensional consistency\u003c\/li\u003e\n  \u003cli\u003eRated to 5000 RPM for medium-speed drive system use\u003c\/li\u003e\n  \u003cli\u003eL190 coupling size code simplifies cross-referencing with mating components\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 L190-series coupling assemblies in industrial rotating equipment drive systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified millwright or mechanical technician. De-energize and lock out the drive system per OSHA lockout\/tagout procedures before removing the existing coupling hub. Verify shaft diameter does not exceed the 1-5\/8 inch maximum bore before pressing or keying the hub onto the shaft. Inspect the mating spider element for wear and replace as needed to ensure full coupling performance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Diameter\u003c\/strong\u003e: 1-5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter (OD)\u003c\/strong\u003e: 4-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4.88 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Speed\u003c\/strong\u003e: 5000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Sintered Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Size Code\u003c\/strong\u003e: L190\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 6.93 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 68514412297\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOVEJOY","offers":[{"title":"Default Title","offer_id":51540171620658,"sku":"68514412297","price":171.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/78efc171d0355ff0651a6aef22b1a05e.jpg?v=1785847907","url":"https:\/\/voomisupply.com\/products\/lovejoy-68514412297-flexible-hub-coupling-1-5-8-in-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
