The hub measures 1.26 inches in outside diameter and 1.772 inches in overall length, with a 3\/8 inch minimum bore diameter. The clamp-style design allows secure shaft engagement without set screws bearing directly on the shaft. Torque capacity is rated at 40 inch-pounds. Installed by mechanical technicians and machine builders, this hub is a component part of a complete Oldham coupling assembly.\u003c\/p\u003e\n\u003cp\u003eThis coupling hub is used in applications where misalignment compensation is required between two rotating shafts, such as in conveyor drives, pump-to-motor connections, encoder mounts, and general-purpose power transmission setups. The polyacetal insert transmits torque between the two hubs while absorbing minor angular and parallel misalignment. The aluminum hub construction keeps rotating mass low, making this hub suitable for servo and stepper motor drive trains as well as light-duty industrial machinery where shaft sizes are in the 3\/8 inch range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClamp-style hub design for positive shaft retention without direct set-screw contact\u003c\/li\u003e\n  \u003cli\u003eAluminum hub construction reduces rotating inertia\u003c\/li\u003e\n  \u003cli\u003ePolyacetal insert accommodates angular and parallel shaft misalignment\u003c\/li\u003e\n  \u003cli\u003e40 inch-pound torque rating suitable for light-duty drive applications\u003c\/li\u003e\n  \u003cli\u003e1.26 inch OD and 1.772 inch overall length in a compact envelope\u003c\/li\u003e\n  \u003cli\u003eSold as a single hub component — order 2 hubs of matching OD plus 1 insert for a complete coupling assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThis hub is one component of a complete Oldham coupling.

Disconnect and lock out all power to the drive system before installing or removing coupling components. Verify shaft and bore dimensions before assembly, and ensure both hubs are fully seated and clamping fasteners are tightened to equipment manufacturer specifications. Do not operate the coupling beyond its rated torque capacity.\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\u003eMinimum Bore Diameter\u003c\/strong\u003e: 3\/8 inch\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\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: 68514458119\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOVEJOY","offers":[{"title":"Default Title","offer_id":51540625424690,"sku":"68514458119","price":146.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a310c38b144918df097c0c37adefc9cc.jpg?v=1785860394","url":"https:\/\/voomisupply.com\/products\/lovejoy-68514458119-oldham-coupling-hub-1-26in-od-3-8in-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
