This cast iron hub accepts a maximum bore diameter of 1-5\/8 inches and a keyway measuring 3\/8 inches wide by 3\/16 inches deep, providing a secure, positive-drive connection to the shaft. With an outer diameter of 6.35 inches and an overall length of 5.06 inches, it is sized for medium-duty industrial drive systems. Licensed mechanics and millwrights install this component as part of a complete flexible coupling assembly on pumps, compressors, fans, and similar rotating equipment.\u003c\/p\u003e\u003cp\u003eThis hub is suited for industrial and commercial drive train installations where rotational power must be transferred between two shafts with some degree of angular, parallel, or axial misalignment. The coupling size code is 9S, and the hub is rated for operation up to 3750 RPM. Typical applications include HVAC mechanical rooms, pump stations, and light industrial machinery where cast iron construction provides adequate strength and wear resistance under continuous-duty cycling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMaximum bore diameter of 1-5\/8 inches for compatibility with standard shaft sizes\u003c\/li\u003e\n\u003cli\u003eKeyway dimensions of 3\/8 inches wide by 3\/16 inches deep for positive-drive shaft engagement\u003c\/li\u003e\n\u003cli\u003e6.35 inch outer diameter and 5.06 inch overall length for medium-duty drive applications\u003c\/li\u003e\n\u003cli\u003eCast iron construction provides durability under continuous rotational load\u003c\/li\u003e\n\u003cli\u003eRated to 3750 RPM for use in standard industrial and commercial equipment\u003c\/li\u003e\n\u003cli\u003eCoupling size code 9S for matching with corresponding flexible coupling components\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement flexible coupling hub for industrial and commercial rotating equipment using size code 9S flexible coupling assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified millwright or mechanical technician. De-energize and lock out the drive motor before removing or installing any coupling component, following LOTO procedures per OSHA 29 CFR 1910.147. Ensure the shaft and bore are clean and free of burrs before pressing the hub into position, and verify keyway alignment before applying load. Do not exceed the rated maximum RPM of 3750 during operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Diameter\u003c\/strong\u003e: 1-5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKeyway Width\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKeyway Depth\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter (OD)\u003c\/strong\u003e: 6.35 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 5.06 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3750 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoupling Size Code\u003c\/strong\u003e: 9S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 6.8 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 68514436159\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOVEJOY","offers":[{"title":"Default Title","offer_id":51538849038642,"sku":"68514436159","price":150.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/95a3e7b045d7bb4af20a0addea27a0c5.jpg?v=1785828294","url":"https:\/\/voomisupply.com\/products\/lovejoy-68514436159-flexible-coupling-hub-1-5-8-in-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
