This shaft measures 1 inch in diameter and 12 inches in overall length, machined from steel with a Rockwell hardness of 60C. The diameter tolerance is held between 0.9990 and 0.9995 inches, providing the close fit required for linear bearings and bushings. The annealed end treatment supports easier machining or press-fit installation at the shaft terminus. Mechanical engineers, maintenance technicians, and machine builders install this type of component in actuator assemblies, slide mechanisms, and automated equipment.\u003c\/p\u003e\n\u003cp\u003eThis linear shaft is suited for light-industrial and commercial mechanical applications where controlled shaft diameter and surface finish are critical. Typical installations include linear bearing rails, rod-end assemblies, pneumatic slide guides, and custom automation frames. The 12-inch length suits shorter-stroke or sub-assembly configurations. The steel construction and 60C hardness make this shaft appropriate for applications with moderate lateral loads and repetitive sliding contact against bronze, polymer, or recirculating-ball linear bearings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1 inch nominal diameter with tight tolerance range of 0.9990 to 0.9995 inches\u003c\/li\u003e\n  \u003cli\u003e12 inches overall length for compact linear motion assemblies\u003c\/li\u003e\n  \u003cli\u003eSteel construction with 60C Rockwell hardness for wear resistance under sliding load\u003c\/li\u003e\n  \u003cli\u003eAnnealed end for improved machinability and press-fit compatibility\u003c\/li\u003e\n  \u003cli\u003eRound cross-section compatible with standard linear bearing bores and shaft supports\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or original-fit linear shaft for mechanical assemblies requiring a 1-inch diameter steel round shaft with close diameter tolerances.

De-energize and lock out all power sources before removing or installing shafting in any powered assembly. Use proper shaft alignment tools to avoid side-loading linear bearings during installation. Do not strike the shaft directly with a steel hammer; use a soft mallet or press to seat the shaft without damaging the surface finish or tolerance zone.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShaft Diameter (Nominal)\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Diameter Tolerance\u003c\/strong\u003e: 0.9990 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Diameter Tolerance\u003c\/strong\u003e: 0.9995 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 60C Rockwell\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShaft Type\u003c\/strong\u003e: Annealed End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.66 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 1 L SMAE L 12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"THOMSON INDUSTRIES","offers":[{"title":"Default Title","offer_id":67905953694002,"sku":"1 L SMAE L 12","price":112.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/936323116bd138bd5acb643b0c3ae47b.jpg?v=1791160754","url":"https:\/\/voomisupply.com\/products\/thomson-industries-1-l-smae-l-12-round-linear-shaft","provider":"Voomi Supply","version":"1.0","type":"link"}
