Its rigid brass design also works well in setups where a \u003cstrong\u003emotor pump coupling rubber\u003c\/strong\u003e option or a precise \u003cstrong\u003ewheel coupling\u003c\/strong\u003e is required. Because of its stable clamping force and durable machining, this adapter supports both small robotics builds and fine mechanical assemblies effectively. \u003cbr\u003e\u003cbr\u003eBy using the four M3 screws, each shaft is tightened securely into the coupler, preventing slip even during continuous rotation. This layout makes the \u003cstrong\u003emotor gearbox coupling\u003c\/strong\u003e dependable in RC models, automation modules, and motion prototypes. Additionally, projects involving \u003cstrong\u003emotor pump coupling rubber\u003c\/strong\u003e interfaces or tighter \u003cstrong\u003ewheel coupling\u003c\/strong\u003e alignments benefit from its rigid, balanced structure.\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003e\u003cstrong\u003eTechnical Details\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eMaterial: Brass\u003c\/li\u003e\n\u003cli\u003eConnection Range: 2mm shaft to 4mm shaft\u003c\/li\u003e\n\u003cli\u003eOverall Length: 20 mm\u003c\/li\u003e\n\u003cli\u003eOuter Diameter: 9 mm\u003c\/li\u003e\n\u003cli\u003eLocking System: M3 tightening screws (4 pcs)\u003c\/li\u003e\n\u003cli\u003eCoupler Type: Straight rigid sleeve\u003c\/li\u003e\n\u003cli\u003eWeight: 8 g\u003c\/li\u003e\n\u003cli\u003eFinish Color: Gold\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eStrong brass body ideal for \u003cstrong\u003emotor gearbox coupling\u003c\/strong\u003e setups\u003c\/li\u003e\n\u003cli\u003eFour M3 screws ensure tight and even clamping\u003c\/li\u003e\n\u003cli\u003eUseful alternative to \u003cstrong\u003emotor pump coupling rubber\u003c\/strong\u003e in rigid systems\u003c\/li\u003e\n\u003cli\u003eReliable torque transfer for precise \u003cstrong\u003ewheel coupling\u003c\/strong\u003e applications\u003c\/li\u003e\n\u003cli\u003eCompact form suitable for confined mechanism layouts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003e\u003cstrong\u003eApplications\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eRobot drive stages and gearbox alignment\u003c\/li\u003e\n\u003cli\u003eRC propulsion systems and miniature power trains\u003c\/li\u003e\n\u003cli\u003eMotion prototypes using \u003cstrong\u003emotor pump coupling rubber\u003c\/strong\u003e alternatives\u003c\/li\u003e\n\u003cli\u003eCustom \u003cstrong\u003ewheel coupling\u003c\/strong\u003e linkages\u003c\/li\u003e\n\u003cli\u003eDIY CNC and mechanical transmission builds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003e\u003cstrong\u003ePhysical Attributes\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eBody Length: 20 mm\u003c\/li\u003e\n\u003cli\u003eSleeve Diameter: 9 mm\u003c\/li\u003e\n\u003cli\u003eBore Diameters: 2 mm and 4 mm\u003c\/li\u003e\n\u003cli\u003eThread Specification: M3\u003c\/li\u003e\n\u003cli\u003eClamp Screws Provided: 4 pcs\u003c\/li\u003e\n\u003cli\u003eTotal Mass: 8 g\u003c\/li\u003e\n\u003cli\u003eBuild Style: Solid cylindrical tube\u003c\/li\u003e\n\u003cli\u003eSurface Texture: Smooth machined brass\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003e\u003cstrong\u003ePackage Includes\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003e1 × Double Pass Brass Coupling (2mm × 4mm)\u003c\/li\u003e\n\u003cli\u003e4 × M3 Clamp Screws\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"KitsGuru","offers":[{"title":"Default Title","offer_id":48429785547004,"sku":"LGRO070","price":59.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/files\/motor-gearbox-coupling-brass-2mm-4mm-1.jpg?v=1764738665","url":"https:\/\/kitsguru.com\/es\/products\/double-pass-brass-universal-adapter-coupling-2mm-x-4mm","provider":"KitsGuru","version":"1.0","type":"link"}
