The triple-bearing design supports rotating workpieces while maintaining accurate alignment and reducing friction at the point of contact. With a maximum workpiece capacity of 1,322.8 pounds and a maximum spindle speed of 3,000 RPM, this unit is built for demanding production and toolroom turning. The standard 60-degree included-angle point is compatible with center-drilled workpieces. The center body is steel construction. Installation and setup are performed by machinists and tool-room technicians.\u003c\/p\u003e\n\u003cp\u003eThe UNK-80 is suited for general-purpose turning applications where a rotating live center is required to support the workpiece at the tailstock end. The MT4 shank fits standard MT4 tailstock bores found on mid-size to larger engine lathes. The 1,322.8-pound workpiece weight rating makes it appropriate for heavier stock turning in production machining, maintenance repair shops, and toolroom environments. The standard point style accommodates center-drilled workpieces across a wide range of shaft and cylindrical part diameters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMT4 taper shank fits standard MT4 tailstock bores on mid-size and larger engine lathes\u003c\/li\u003e\n  \u003cli\u003eTriple-bearing design supports high radial and axial loads up to 1,322.8 pounds workpiece capacity\u003c\/li\u003e\n  \u003cli\u003e3,000 RPM maximum speed rating for production turning operations\u003c\/li\u003e\n  \u003cli\u003eStandard 60-degree included-angle point accommodates center-drilled workpieces\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in machine shop environments\u003c\/li\u003e\n  \u003cli\u003eNon-carbide-tipped standard point suitable for general-purpose use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or upgrade live center for engine lathes equipped with an MT4 tailstock bore.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist or toolroom technician. Before installing or removing the center, ensure the lathe is fully powered down and the spindle is at rest. Clean the MT4 tailstock bore and shank taper thoroughly before seating to ensure proper contact and alignment. Use a suitable drift punch and soft mallet to eject the center from the tailstock bore when removal is required — never apply side force to the point or rotating head during removal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: 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: Triple\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Style\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Workpiece Weight\u003c\/strong\u003e: 1,322.8 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3,000\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Diameter\u003c\/strong\u003e: 1.2992 inches (33.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Length\u003c\/strong\u003e: 3.2100 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Length\u003c\/strong\u003e: 1.2400 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 2.0472 inches (52.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7.5591 inches (192.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Line Diameter\u003c\/strong\u003e: 31.60 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCarbide-Tipped Point\u003c\/strong\u003e: No\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: 2.52 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: UNK-80\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51697789534514,"sku":"UNK-80","price":142.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/39f378f3dc88de321aff556f537b7e8c.jpg?v=1788354326","url":"https:\/\/voomisupply.com\/products\/value-collection-unk-80-live-center-taper-shank-mt4","provider":"Voomi Supply","version":"1.0","type":"link"}
