With a 1.25-inch inside diameter and a 520-pound dynamic load capacity, this fixed-alignment bushing is built to handle demanding reciprocating loads in tooling and industrial equipment. The round bore and closed bearing style keep the ball elements retained and protected, making it suitable for die set guide post assemblies and similar precision machinery. Machinists, toolmakers, and maintenance technicians install this component as part of die set guide systems requiring consistent, repeatable linear travel.\u003c\/p\u003e\n\u003cp\u003eThe DS20 is used in die set assemblies where a guided bushing must ride along a hardened guide post with minimal play and consistent load transfer. Its fixed alignment style means it is intended for installations where shaft and housing alignment is controlled at assembly. This bushing is a direct fit in applications calling for a 1.25-inch bore linear ball bushing with a 2.31-inch outside diameter, including punch press tooling, stamping dies, and precision fixture guides commonly found in metalworking and manufacturing environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.25-inch inside diameter with a precision bore diameter of 1.2498 inches for close-tolerance shaft fit\u003c\/li\u003e\n  \u003cli\u003e520-pound dynamic load capacity for use in demanding reciprocating and linear load applications\u003c\/li\u003e\n  \u003cli\u003eClosed bearing style retains ball elements and provides protection in die set environments\u003c\/li\u003e\n  \u003cli\u003eFixed alignment style for installations with controlled shaft and housing alignment\u003c\/li\u003e\n  \u003cli\u003e2.31-inch outside diameter with a matching center-to-center bore length of 2.31 inches\u003c\/li\u003e\n  \u003cli\u003eRound bore design for standard cylindrical guide post applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct installation component for die set guide post assemblies requiring a closed, fixed-alignment linear ball bushing with a 1.25-inch bore and 2.31-inch outside diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by toolmakers or maintenance technicians familiar with die set assembly procedures. Press the bushing into the housing bore using an arbor press and appropriate installation tooling to avoid damage to the ball retainer or bore surface. Ensure the guide post and housing bore are clean and within specified tolerances before installation. Always de-energize and lock out the press or machine before servicing die set components.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDynamic Load Capacity\u003c\/strong\u003e: 520 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter (Precision)\u003c\/strong\u003e: 1.2498 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 2.31 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter-to-Center Bore Length\u003c\/strong\u003e: 2.31 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBearing Type\u003c\/strong\u003e: Linear Ball Bushing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBearing Style\u003c\/strong\u003e: Closed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Type\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAlignment Style\u003c\/strong\u003e: Fixed\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: THOMSON INDUSTRIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: DS20\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"THOMSON INDUSTRIES","offers":[{"title":"Default Title","offer_id":67916634751282,"sku":"DS20","price":710.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/39f0347ed6dec4cfbabbbb51fe51caba_d374835a-71db-4523-b97a-0f10c37fb5bb.jpg?v=1791258711","url":"https:\/\/voomisupply.com\/products\/thomson-industries-ds20-die-set-linear-ball-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
