It features an aluminum hub paired with a stainless steel bellows element, combining lightweight construction with corrosion resistance. The coupling accepts a minimum bore diameter of 3\/8 inch, measures 1.28 inches in outside diameter, and has an overall length of 1.614 inches. With a rated torque of 40 inch-pounds, it suits light-duty motion control, servo, and positioning system installations. Mechanical contractors and machine builders working with small-frame motors, encoders, or pumps typically install this type of coupling.\u003c\/p\u003e\n\u003cp\u003eThis coupling is used in residential and light commercial mechanical systems where precise shaft alignment and vibration dampening are required. The bellows design accommodates angular, parallel, and axial misalignment while maintaining consistent torque transmission. It is well suited for pump drives, HVAC fan assemblies, and instrumentation setups where a compact, corrosion-resistant coupling is needed. The clamp-style hub eliminates the need for set screws, providing a secure shaft grip without marring shaft surfaces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum hub construction keeps weight low while providing a rigid clamping surface\u003c\/li\u003e\n  \u003cli\u003eStainless steel bellows element resists corrosion and accommodates multi-directional misalignment\u003c\/li\u003e\n  \u003cli\u003eClamp-style attachment secures to shaft without set screws\u003c\/li\u003e\n  \u003cli\u003eRated torque of 40 inch-pounds suitable for light-duty drive applications\u003c\/li\u003e\n  \u003cli\u003eCompact profile at 1.614 inches OAL and 1.28 inches OD fits space-constrained installations\u003c\/li\u003e\n  \u003cli\u003eSeries BWC, size code BWC41 for straightforward cross-referencing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit coupling for light-duty mechanical drive systems requiring a 3\/8 inch bore bellows clamp coupling in the BWC series.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanical technician or machine builder. De-energize and lock out all power to the drive system before installing or removing the coupling. Verify shaft diameter matches the minimum bore specification before mounting, and confirm shaft ends are clean and free of burrs. Torque all clamp fasteners to the fastener manufacturer specifications and check alignment after installation per standard mechanical drive practices.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Type\u003c\/strong\u003e: Bellows Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: BWC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Size Code\u003c\/strong\u003e: BWC41\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.28 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.614 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRated Torque\u003c\/strong\u003e: 40 inch-pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Aluminum Hub with Stainless Steel Bellows\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Clamp Style\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.16 pounds\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: 68514477390\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOVEJOY","offers":[{"title":"Default Title","offer_id":51541525037362,"sku":"68514477390","price":290.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b636af58714acba2d1f6b52109404d22.jpg?v=1785878323","url":"https:\/\/voomisupply.com\/products\/lovejoy-68514477390-flexible-bellows-clamp-3-8-in-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
