Built on an MT4 taper shank, it supports workpieces up to 5,060 pounds and spins to a maximum of 5,500 RPM. The quad bearing configuration allows the center point to rotate with the workpiece, reducing friction and heat buildup during extended cuts. The point is steel construction with an included angle of 60 degrees and a point diameter of 1.14 inches. Machinists and toolroom technicians use this type of live center where rigidity, load capacity, and rotational accuracy are critical.\u003c\/p\u003e\n\u003cp\u003eThis live center is suited for manual and CNC lathes equipped with an MT4 tailstock. It is appropriate for medium-to-heavy turning applications in production shops, tool rooms, and job shops where workpiece weight and spindle speed demands exceed the capacity of lighter-duty centers. The 0.0001 inch accuracy rating makes it a viable choice for finish turning and close-tolerance work. No carbide-tipped point is included, which is a consideration when turning hardened materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMT4 Morse Taper shank for secure tailstock engagement\u003c\/li\u003e\n  \u003cli\u003eQuad bearing design supports rotation with the workpiece, reducing friction and wear\u003c\/li\u003e\n  \u003cli\u003eMaximum workpiece weight capacity of 5,060 pounds\u003c\/li\u003e\n  \u003cli\u003eMaximum spindle speed of 5,500 RPM\u003c\/li\u003e\n  \u003cli\u003eAccuracy rated to 0.0001 inches for close-tolerance turning\u003c\/li\u003e\n  \u003cli\u003eThrust load rating of 1,438 pounds for heavy axial cutting forces\u003c\/li\u003e\n  \u003cli\u003e60-degree included point angle, standard for general turning work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style live center replacement or addition for lathes with an MT4 Morse Taper tailstock socket.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Before seating the taper, power down the lathe and confirm the tailstock bore and taper size match MT4 specifications. Clean the tailstock socket and taper shank thoroughly to ensure full contact and prevent fretting. Never use the center beyond its rated RPM or workpiece weight limits, as overloading the bearings can cause premature failure or loss of workpiece control.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Morse Taper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTaper Size\u003c\/strong\u003e: MT4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBearing Type\u003c\/strong\u003e: Quad\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Workpiece Weight\u003c\/strong\u003e: 5,060 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 5,500\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrust Load\u003c\/strong\u003e: 1,438 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.0001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Diameter\u003c\/strong\u003e: 1.14 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Length\u003c\/strong\u003e: 1.58 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 2.40 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 2.17 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCarbide-Tipped Point\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 4.15 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23153103\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: DORIAN TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 73310148221\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DORIAN TOOL","offers":[{"title":"Default Title","offer_id":67910630670642,"sku":"73310148221","price":820.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_daac93ea-3766-4610-8fce-f4ea72dc3f23.jpg?v=1791199265","url":"https:\/\/voomisupply.com\/products\/dorian-tool-73310148221-live-center-mt4-morse-taper","provider":"Voomi Supply","version":"1.0","type":"link"}
