It features a 3\/4-inch inside bore diameter and a 4.402-inch outside diameter, with a pitch diameter of 4.456 inches. The pulley accepts H-series timing belts with a 1-inch belt width. Constructed from steel cast iron, this pulley delivers the rigidity and wear resistance required for continuous-duty drive train applications. Installation is typically performed by mechanical technicians or millwrights working on conveyor systems, machine drives, or other synchronized belt-drive assemblies.\u003c\/p\u003e\n\u003cp\u003eThis timing belt pulley is suited for use in industrial machinery, conveyor lines, and synchronous drive systems that use H-profile timing belts. The H belt trade size designation indicates compatibility with standard H-pitch belt configurations commonly found in mid-range power transmission setups. It is appropriate for both OEM replacement and new-build drive system configurations where precise tooth engagement and consistent belt tracking are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e28-tooth profile for accurate synchronous belt engagement\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch bore diameter for direct shaft mounting\u003c\/li\u003e\n  \u003cli\u003e4.456-inch pitch diameter for precise drive ratio calculations\u003c\/li\u003e\n  \u003cli\u003e4.402-inch outside diameter for standard H-series belt fitment\u003c\/li\u003e\n  \u003cli\u003eSteel cast iron construction for high rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eCompatible with 1-inch wide H-profile timing belts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with H-series timing belts with a 1-inch belt width.

Shut down and lock out all power to the drive system before replacing or installing the pulley. Ensure the shaft diameter matches the 3\/4-inch bore before mounting, and verify belt tension and alignment according to the drive system manufacturer specifications. Proper alignment of the pulley to mating components is critical to prevent premature belt and bearing wear.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Teeth\u003c\/strong\u003e: 28\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 4.402 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch Diameter\u003c\/strong\u003e: 4.456 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Width\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBelt Trade Size\u003c\/strong\u003e: H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 7.8 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 28H1006FSPB3\/4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720968536370,"sku":"28H1006FSPB3\/4","price":194.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d46591aaf44e6b15542b44eb54971f95.jpg?v=1788571618","url":"https:\/\/voomisupply.com\/products\/value-collection-28h1006fspb3-4-timing-belt-pulley-28t","provider":"Voomi Supply","version":"1.0","type":"link"}
