It measures 20 millimeters in diameter and 39 inches in overall length, with a 6mm keyway cut to accept a standard key for positive rotational engagement. This type of shaft is used in linear motion systems where the shaft must transmit torque as well as support radial loads. Machinists, mechanical assemblers, and motion system technicians install this component as part of linear actuator assemblies, conveyor drives, and similar industrial mechanisms.\u003c\/p\u003e\n\u003cp\u003eThis shaft is suited for light-to-medium duty linear and rotary motion applications in industrial machinery. The 1045 steel grade offers a balance of strength and machinability, making it appropriate for precision-fit bearing bores, shaft couplings, and keyed hub assemblies. It is commonly specified in OEM machine builds and field repairs where a standard metric shaft diameter is required. The 39-inch length allows for single-span installations or can be cut to length in the field to suit the application.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e20mm shaft diameter machined to linear shafting tolerances for compatibility with standard metric linear bearings\u003c\/li\u003e\n  \u003cli\u003e6mm keyway provides positive torque transmission and prevents shaft rotation within keyed hubs or couplings\u003c\/li\u003e\n  \u003cli\u003e1045 carbon steel construction offers good tensile strength and machinability\u003c\/li\u003e\n  \u003cli\u003e39-inch overall length accommodates a range of span requirements and can be cut to length\u003c\/li\u003e\n  \u003cli\u003eSold as a single shaft (package quantity of 1)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or build component for industrial linear motion assemblies requiring a 20mm keyed round shaft in 1045 steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a machinist or mechanical technician. De-energize all equipment and lock out power before removing or installing shafting in a live machine. Use appropriate shaft support fixtures and ensure mating bearings, couplings, and keyways are properly aligned before final assembly. Refer to applicable machinery standards and the equipment manufacturer's service documentation for torque and fit specifications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShaft Diameter\u003c\/strong\u003e: 20mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 39 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShaft Type\u003c\/strong\u003e: Keyed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKey Size\u003c\/strong\u003e: 6mm\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: 1045\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.43 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 30266700\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: 20MMK1045ST-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":68388764746034,"sku":"20MMK1045ST-3","price":190.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8921e72356f8e4b3556a408fc6b8b804_102b393c-a29c-499e-86d9-897c0eef8fe7.jpg?v=1793904809","url":"https:\/\/voomisupply.com\/products\/value-collection-20mmk1045st-3-round-linear-shaft","provider":"Voomi Supply","version":"1.0","type":"link"}
