It features a 1.375-inch bore machined to size for a slip fit on standard shafts, eliminating the need for field boring. Constructed from high-strength cast iron, this Size 7 flange handles up to 1.2 horsepower at 100 RPM with EPDM or Neoprene sleeves, and up to 4.6 horsepower at 100 RPM with a Hytrel sleeve. The flange is rated to a maximum of 5250 RPM. Industrial maintenance technicians and millwrights install this component as part of a complete sleeve coupling assembly connecting two shaft ends.\u003c\/p\u003e\n\u003cp\u003eThis spacer flange is suited for general industrial drive applications where a sleeve coupling connects a motor or gearbox shaft to driven equipment. The spacer design allows for axial separation between shaft ends, which aids in installation and removal without requiring equipment to be repositioned. The 4.625-inch flange diameter and overall coupling length of 2.8125 inches make it a practical fit in standard Size 7 sleeve coupling installations found in pumps, fans, conveyors, and similar rotating equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh-strength cast iron construction for durability in industrial drive environments\u003c\/li\u003e\n  \u003cli\u003eBored-to-size at 1.375 inches for immediate slip fit on standard shafts\u003c\/li\u003e\n  \u003cli\u003eType S spacer flange design allows installation and removal without moving connected equipment\u003c\/li\u003e\n  \u003cli\u003eRated to 5250 RPM maximum speed\u003c\/li\u003e\n  \u003cli\u003eCompatible with EPDM, Neoprene, and Hytrel sleeve elements at Size 7\u003c\/li\u003e\n  \u003cli\u003eSize 7 coupling code for straightforward cross-reference and replacement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation spacer flange for Size 7 sleeve coupling assemblies. Sleeve element horsepower ratings vary by element material: 1.2 hp at 100 RPM with EPDM or Neoprene elements, and 4.6 hp at 100 RPM with Hytrel elements.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a millwright or maintenance mechanic. De-energize and lock out the drive equipment before handling any coupling components, following OSHA lockout\/tagout procedures. Inspect the shaft for burrs or damage before sliding the flange into position, and verify shaft diameter matches the 1.375-inch bore before installation. Do not exceed the rated maximum speed of 5250 RPM in the assembled drive.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Type\u003c\/strong\u003e: Bored to Size\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Size Code\u003c\/strong\u003e: 7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlange Diameter\u003c\/strong\u003e: 4.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 4.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub End Outside Diameter\u003c\/strong\u003e: 3.9375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Overall Length\u003c\/strong\u003e: 2.8125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Through Bore\u003c\/strong\u003e: 1.84375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Flange Type Code\u003c\/strong\u003e: S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Type\u003c\/strong\u003e: Spacer Flange\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Strength Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMax RPM\u003c\/strong\u003e: 5250 rpm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHorsepower at 100 RPM (EPDM and Neoprene)\u003c\/strong\u003e: 1.2 hp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHorsepower at 100 RPM (Hytrel)\u003c\/strong\u003e: 4.6 hp\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: TB WOODS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TB-7S138\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TB WOODS","offers":[{"title":"Default Title","offer_id":51383084122418,"sku":"TB-7S138","price":86.28,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312670222.jpg?v=1782587613","url":"https:\/\/voomisupply.com\/products\/tb-woods-tb-7s138-sleeve-coupling-spacer-flange-size-7","provider":"Voomi Supply","version":"1.0","type":"link"}
