With 15 teeth, a diametral pitch of 12, and a 0.5 inch bore diameter, this gear delivers precise torque transfer in compact drive assemblies. The 20-degree pressure angle provides a strong tooth profile suited for moderate-load mechanical systems. Machinists, millwrights, and industrial maintenance technicians install this gear in equipment where two intersecting shafts must rotate at the same speed in perpendicular planes.\u003c\/p\u003e\n\u003cp\u003eThis miter gear is used in light-to-medium duty industrial and commercial machinery, including conveyors, packaging equipment, agricultural machinery, and general power transmission assemblies. Its 1.25 inch pitch diameter and 1.375 inch outside diameter make it a practical fit for compact gearboxes and custom drive trains where space is limited. The 1.0 inch hub diameter and 0.5 inch hub projection provide a solid mounting footprint for secure shaft engagement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e15-tooth steel construction with a diametral pitch of 12 for consistent load distribution\u003c\/li\u003e\n  \u003cli\u003e20-degree pressure angle for improved tooth strength and reduced backlash sensitivity\u003c\/li\u003e\n  \u003cli\u003e0.5 inch bore diameter accepts standard half-inch shafting\u003c\/li\u003e\n  \u003cli\u003e1.0 inch hub diameter with 0.5 inch hub projection for stable shaft mounting\u003c\/li\u003e\n  \u003cli\u003eFace width of 0.29 inches suited for compact gear train configurations\u003c\/li\u003e\n  \u003cli\u003eSteel material provides durability in industrial operating environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit miter gear for industrial power transmission assemblies requiring a 12 diametral pitch, 15-tooth, 0.5 inch bore steel miter gear at a 90-degree shaft intersection.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified millwright or mechanical technician. De-energize and lock out the drive system before removing or installing any gear components, following applicable OSHA lockout\/tagout procedures. Ensure the mating miter gear matches the diametral pitch, pressure angle, and tooth count of this gear before assembly. Inspect bore fit and keyway alignment to verify proper shaft engagement before returning the drive to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGear Type\u003c\/strong\u003e: Miter\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Teeth\u003c\/strong\u003e: 15\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiametral Pitch\u003c\/strong\u003e: 12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Angle\u003c\/strong\u003e: 20 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch Diameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFace Width\u003c\/strong\u003e: 0.29 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 1.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Projection\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 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: BOSTON GEAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12154\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BOSTON GEAR","offers":[{"title":"Default Title","offer_id":67950409220402,"sku":"12154","price":74.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0b47aa118ebea1ea1002be9e3866188d_e5850bf9-5e9a-434d-8b5b-a1ca38b6e940.jpg?v=1791716552","url":"https:\/\/voomisupply.com\/products\/boston-gear-12154-miter-gear-15-teeth-1-2-inch-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
