Machined from hardened steel with a Rockwell hardness of 60 to 65C, this shaft provides the rigidity and surface quality required in linear bearing systems. The shaft diameter is 12mm (nominally 0.472 inches) with a tight tolerance range of 0.4720 inches to 0.4724 inches, ensuring consistent fit with compatible linear bearings and bushings. At 60 inches in overall length, it suits a wide range of industrial and automation assemblies. Installation is performed by mechanical and automation technicians in both OEM equipment builds and aftermarket repair applications.\u003c\/p\u003e\n\u003cp\u003eThis linear shaft is suited for use in linear motion systems found in industrial machinery, automation equipment, CNC assemblies, and material handling systems. The standard shaft type makes it a direct-fit replacement or new-build component wherever a 12mm diameter hardened steel shaft of 60 inches length is specified. Its hardness and diameter tolerance make it compatible with standard 12mm linear bearings, pillow block assemblies, and open linear guides commonly used in light-to-medium-duty motion systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHardened steel construction with 60 to 65C Rockwell hardness for wear resistance\u003c\/li\u003e\n  \u003cli\u003eTight diameter tolerance of 0.4720 inches to 0.4724 inches for precision bearing fit\u003c\/li\u003e\n  \u003cli\u003e12mm (0.472 inch) nominal shaft diameter in standard configuration\u003c\/li\u003e\n  \u003cli\u003e60 inches overall length accommodates a wide range of travel distances\u003c\/li\u003e\n  \u003cli\u003eStandard shaft type for broad compatibility with linear bearing systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-build shaft for 12mm linear motion systems using standard-tolerance hardened steel round shafting.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by mechanical technicians or automation engineers. Ensure mating linear bearings and support rail end blocks are rated for 12mm shafting before assembly. Secure shaft ends in appropriate end support blocks and verify alignment before loading the system. Follow equipment manufacturer torque specifications for all fasteners and consult applicable machinery safety standards during integration.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShaft Diameter\u003c\/strong\u003e: 12mm (0.472 inches nominal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 60 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Diameter Tolerance\u003c\/strong\u003e: 0.4720 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Diameter Tolerance\u003c\/strong\u003e: 0.4724 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: 60 to 65C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShaft Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3 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: THOMSON INDUSTRIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: QSM 12 L 60\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"THOMSON INDUSTRIES","offers":[{"title":"Default Title","offer_id":67918470971698,"sku":"QSM 12 L 60","price":112.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f40dc496edc3bc4ba5885fdf68cc9387_776488f9-1498-4d71-89e5-024dfa496a03.jpg?v=1791270162","url":"https:\/\/voomisupply.com\/products\/thomson-industries-qsm-12-l-60-round-linear-shaft","provider":"Voomi Supply","version":"1.0","type":"link"}
