Constructed from aluminum with a polyacetal insert, this hub delivers flexibility and misalignment compensation between connected shafts. It has an outside diameter of 1.26 inches, an overall length of 1.772 inches, and accommodates a minimum bore diameter of 0.5 inches. The clamp-style design provides secure shaft engagement without the need for keyways in all configurations. Rated at 40 inch-pounds of torque, this hub suits light-duty industrial, HVAC, and mechanical drive installations where controlled flexibility and low backlash are required.\u003c\/p\u003e\n\u003cp\u003eThis coupling hub is used in mechanical drive systems where two rotating shafts require a flexible connection that can tolerate angular, parallel, or axial misalignment. Typical applications include small motor-to-shaft couplings in HVAC equipment, pump drives, and light industrial machinery. Note that a complete Oldham coupling assembly requires two hubs of the same outside diameter and one insert. Bores between the two hubs may differ, making this hub suitable for connecting shafts of different diameters within the same drive train.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClamp-style hub design for secure, positive shaft retention\u003c\/li\u003e\n  \u003cli\u003eAluminum hub construction for lightweight strength and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003ePolyacetal insert provides flexible, low-backlash torque transmission\u003c\/li\u003e\n  \u003cli\u003eRated at 40 inch-pounds torque capacity\u003c\/li\u003e\n  \u003cli\u003eAccommodates misalignment between connected shafts\u003c\/li\u003e\n  \u003cli\u003eTwo hubs plus one insert required for a complete coupling assembly — bores may differ between hubs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation Oldham coupling hub for mechanical drive systems requiring a 1.26 inch outside diameter clamp-style hub with a 0.5 inch minimum bore. Complete assembly requires two hubs of matching outside diameter and one compatible polyacetal insert ordered separately.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a qualified millwright, mechanical technician, or HVAC service technician. Disconnect and lock out all power to the drive system before beginning hub installation or removal. Ensure shaft surfaces are clean and free of burrs before seating the hub bore, and verify that both hubs share the same outside diameter before ordering the mating insert. Do not exceed the rated torque of 40 inch-pounds for this hub size.\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\u003eStyle\u003c\/strong\u003e: Clamp Style\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.26 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.772 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTorque Rating\u003c\/strong\u003e: 40 inch-pounds\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: 0.05 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: 68514458121\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOVEJOY","offers":[{"title":"Default Title","offer_id":51539425820978,"sku":"68514458121","price":146.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/979e00694e9e2d343e968df6ef784062.jpg?v=1785840059","url":"https:\/\/voomisupply.com\/products\/lovejoy-68514458121-oldham-coupling-hub-aluminum-1-26-od","provider":"Voomi Supply","version":"1.0","type":"link"}
