Machined from sintered iron, this hub accepts a minimum bore diameter of 0.25 inches and a maximum bore diameter of 0.394 inches, with an outside diameter of 1.36 inches and an overall length of 2 inches. It transmits torque up to 43.20 inch-pounds (4.88 newton-meters) between connected shafts while accommodating minor misalignment. Mechanical technicians and industrial maintenance professionals install this hub as part of a complete coupling assembly in drive systems across HVAC, pumping, and light industrial equipment.\u003c\/p\u003e\n\u003cp\u003eThis hub is suited for residential and commercial mechanical drive applications where a compact, low-cost flexible coupling is needed. The L070 series is a widely used jaw coupling platform found in small motor-to-pump drives, fan assemblies, and gearbox connections. Note that a complete coupling requires two hubs and one spider insert, which must be ordered separately. This hub ships as a single unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSintered iron construction provides durability in light-to-medium duty drive applications\u003c\/li\u003e\n  \u003cli\u003eBore range of 0.25 inches to 0.394 inches accommodates common small shaft sizes\u003c\/li\u003e\n  \u003cli\u003eOutside diameter of 1.36 inches fits compact drive envelopes\u003c\/li\u003e\n  \u003cli\u003eRated torque of 43.20 inch-pounds (4.88 N\/m) suitable for fractional horsepower drive trains\u003c\/li\u003e\n  \u003cli\u003eL070 series coupling size code for straightforward cross-referencing and replacement sourcing\u003c\/li\u003e\n  \u003cli\u003eSingle hub sold per package — order two hubs and one spider for a complete coupling assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement hub for L070 series jaw-type flexible coupling assemblies. Two hubs and one spider insert are required to complete a functional coupling. Compatible spider and mating hub must share the L070 series designation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed millwright or mechanical technician. Before servicing any coupling, de-energize and lock out the drive motor per NFPA 70E and site-specific LOTO procedures. Hubs should be pressed or keyed onto shafts according to the shaft and bore tolerances of the application — do not force a hub onto an oversized shaft. Inspect the spider insert for wear at each service interval and replace if elastomeric elements show cracking, compression set, or missing segments.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: L070\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Type\u003c\/strong\u003e: Hub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Coupling Hub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Sintered Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.25 inches (6.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Diameter\u003c\/strong\u003e: 0.394 inches (10.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.36 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRated Torque\u003c\/strong\u003e: 43.20 inch-pounds (4.88 N\/m)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.23 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: 68514441452\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOVEJOY","offers":[{"title":"Default Title","offer_id":51538899501362,"sku":"68514441452","price":20.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9ff2c96e4fdfc020ee6833f433a2119.jpg?v=1785829093","url":"https:\/\/voomisupply.com\/products\/lovejoy-68514441452-flexible-coupling-hub-l070-sintered-iron","provider":"Voomi Supply","version":"1.0","type":"link"}
