The shaft measures 0.625 inches in nominal diameter with a close tolerance range of 0.6240 to 0.6245 inches and a total length of 20 inches. It is designed for use in linear motion assemblies where a hardened, precision-ground shaft supports sliding bearings or linear bushings. Mechanical engineers, machine builders, and maintenance technicians install this type of shaft in actuators, automation equipment, and industrial motion systems.\u003c\/p\u003e\u003cp\u003eThis shaft is suited for linear motion applications in both industrial and commercial settings. The 20-inch length makes it appropriate for mid-travel linear slides, conveyor guide systems, and custom actuator builds. The tight diameter tolerance supports accurate alignment with standard linear bearings and bushings sized for 5\/8-inch shafting. It is a standard-catalog component intended for direct installation or cut-to-length use in new builds and replacement applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1566 steel construction provides high strength and wear resistance in linear motion service\u003c\/li\u003e\n\u003cli\u003eHardness of 60 to 65 Rockwell C for extended service life under sliding contact loads\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of 0.6240 to 0.6245 inches ensures precise fit with mating linear bearings\u003c\/li\u003e\n\u003cli\u003e20-inch overall length supports a wide range of linear travel requirements\u003c\/li\u003e\n\u003cli\u003eStandard 5\/8-inch nominal diameter compatible with widely available linear motion components\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-build component for linear motion assemblies using standard 5\/8-inch round shaft bearings and bushings.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by mechanical technicians or machine builders as part of a linear motion assembly. Secure all bearing blocks and end supports before loading the shaft, and verify alignment to prevent side-loading on mating bearings. Clean the shaft surface before installation to remove any contamination that could affect bearing fit or introduce abrasion. Consult applicable machinery safety standards and de-energize any connected actuators before replacing a shaft in an existing assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft Type\u003c\/strong\u003e: Standard Round Linear Shaft\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 0.625 inches (5\/8 inch fraction)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Diameter Tolerance\u003c\/strong\u003e: 0.6240 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Diameter Tolerance\u003c\/strong\u003e: 0.6245 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 20 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 1566\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 60 to 65 Rockwell C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.72 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 5\/8 L CTL 20\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"THOMSON INDUSTRIES","offers":[{"title":"Default Title","offer_id":67910204522802,"sku":"5\/8 L CTL 20","price":65.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/936323116bd138bd5acb643b0c3ae47b_ff011688-22b8-4f7c-af11-cdfee05b7d3a.jpg?v=1791196666","url":"https:\/\/voomisupply.com\/products\/thomson-industries-5-8-l-ctl-20-round-linear-shaft","provider":"Voomi Supply","version":"1.0","type":"link"}
