The hub features an aluminum body paired with a polyacetal (acetal resin) insert that absorbs angular and parallel misalignment between connected shafts. With a minimum bore diameter of 0.25 inches, an outside diameter of 0.984 inches, and an overall length of 1.535 inches, this component is sized for compact drive assemblies. Rated at 18 inch-pounds of torque, it is suitable for light-duty servo, stepper motor, and instrumentation drive trains. Installation is handled by mechanical technicians and machine builders working on automation and motion systems.\u003c\/p\u003e\n\u003cp\u003eThis coupling hub fits residential and light commercial automation equipment, small conveyor drives, pump drives, and instrumentation assemblies where rotational accuracy and vibration damping are required. The Oldham design uses a floating center disk (insert) to transmit torque while allowing lateral shaft offset. This hub is part of the LOVEJOY MOL series. Note that a complete Oldham coupling requires two hubs of matching outside diameter and one center insert — all three components must be ordered separately. Bores on the two hubs can differ, allowing connection of shafts of different diameters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum hub construction with polyacetal insert for corrosion resistance and light weight\u003c\/li\u003e\n  \u003cli\u003eClamp-style hub secures to shaft without set screws for even clamping force\u003c\/li\u003e\n  \u003cli\u003eAccommodates parallel and angular shaft misalignment inherent to the Oldham design\u003c\/li\u003e\n  \u003cli\u003eRated torque capacity of 18 inch-pounds for light-duty drive applications\u003c\/li\u003e\n  \u003cli\u003eCompact geometry: 0.984 inches OD and 1.535 inches overall length for space-constrained assemblies\u003c\/li\u003e\n  \u003cli\u003ePart of the MOL series (size code MOL25C) for easy cross-reference with compatible inserts and mating hubs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThis hub is part of the LOVEJOY MOL series (size code MOL25C). A complete coupling assembly requires two MOL25C hubs of the same outside diameter and one corresponding MOL series center insert. Hub bores may differ between the two hubs to accommodate shafts of unequal diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by mechanical technicians or machine builders. Disconnect and lock out all power to the drive system before disassembling or mounting coupling components. Clamp-style hubs require the bore to be clean and free of burrs before insertion of the shaft. Confirm shaft diameters and hub alignment before final clamp torque is applied — do not force misaligned shafts into the assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Type\u003c\/strong\u003e: Oldham Coupling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Size Code\u003c\/strong\u003e: MOL25C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.984 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.535 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTorque Rating\u003c\/strong\u003e: 18 inch-pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Clamp Style\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Aluminum Hub with Polyacetal Insert\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: 68514458617\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOVEJOY","offers":[{"title":"Default Title","offer_id":51542706356530,"sku":"68514458617","price":119.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/96411907254af2fcc596e413268c13d6.jpg?v=1785904911","url":"https:\/\/voomisupply.com\/products\/lovejoy-68514458617-oldham-coupling-hub-1-4-in-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
