This compact coupling delivers a \u003cstrong\u003erated torque of 1.5 Nm\u003c\/strong\u003e and withstands a \u003cstrong\u003emaximum torque of 3 Nm\u003c\/strong\u003e, providing reliable torque transmission in critical motion control applications. Its \u003cstrong\u003eoverall length L of 31 mm\u003c\/strong\u003e and \u003cstrong\u003eouter diameter D of 22 mm\u003c\/strong\u003e allow seamless integration in constrained spaces without compromising performance. Built using an \u003cstrong\u003ealuminum body\u003c\/strong\u003e for lightweight strength and \u003cstrong\u003estainless steel bellows\u003c\/strong\u003e for enhanced durability, this part meets stringent industrial automation requirements. Its combination of robust materials and precise design makes it an ideal choice for reliable coupling in demanding environments.\u003c\/p\u003e\n\n\u003cp\u003eThe technical capabilities of the \u003cstrong\u003e8MSA4M.E0-31\u003c\/strong\u003e coupling center on its exceptional misalignment tolerance and clamping precision. It accommodates a \u003cstrong\u003eparallel misalignment of 0.2 mm\u003c\/strong\u003e and an \u003cstrong\u003eangular misalignment of 2°\u003c\/strong\u003e, thus reducing stress on connected shafts and bearings. The coupling secures shafts using a reliable \u003cstrong\u003eset screw clamping method\u003c\/strong\u003e, ensuring a firm hold under dynamic loads. Dual \u003cstrong\u003ebore diameters D1 and D2 of 8 mm\u003c\/strong\u003e enable symmetric shaft connections, simplifying installation and reducing inventory. The coupling’s \u003cstrong\u003ematerial – body: aluminum\u003c\/strong\u003e and \u003cstrong\u003ematerial – bellows: stainless steel\u003c\/strong\u003e combine to offer high strength-to-weight ratio and superior fatigue resistance.\u003c\/p\u003e\n\n\u003cp\u003eOperational features of the \u003cstrong\u003e8MSA4M.E0-31\u003c\/strong\u003e include an impressive \u003cstrong\u003eoperating temperature range of –40°C to +120°C\u003c\/strong\u003e, guaranteeing stable performance in extreme cold and high-heat conditions. The stainless steel bellows provide inherent flexibility, compensating for minor shaft misalignments while maintaining constant torque transmission. This flexibility minimizes bearing loads and extends the service life of connected equipment, reducing overall maintenance needs. Its compact dimensions and high torsional stiffness deliver precise rotational response, making it suitable for high-speed and high-precision industrial automation tasks.\u003c\/p\u003e\n\n\u003cp\u003eIntegration into existing systems is straightforward thanks to the coupling’s standardized dimensions and robust design. The \u003cstrong\u003e8MS Three Phase Synchronous Motors\u003c\/strong\u003e series compatibility ensures plug-and-play installation on B \u0026amp; R drives and motors. Typical applications include servo motor to gearbox connections, conveyor drives, packaging machinery, and robotic joints where precision, durability, and minimal backlash are critical. Engineers will appreciate the combination of lightweight construction, high torque capacity, and misalignment tolerance that the \u003cstrong\u003e8MSA4M.E0-31\u003c\/strong\u003e coupling brings to industrial automation solutions.\u003c\/p\u003e","brand":"B \u0026 R Automation","offers":[{"title":"Unused Surplus","offer_id":51689760555309,"sku":null,"price":13663.0,"currency_code":"USD","in_stock":true},{"title":"Refurbished","offer_id":52022411985197,"sku":null,"price":9113.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/7696\/9517\/files\/8MS_Three_Phase_Synchronous_Motor_Series__f1dd75b7-473e-4008-891a-5e73d2a3bdbe.webp?v=1757359245","url":"https:\/\/servosupplier.com\/products\/8msa4me0-31","provider":"Servo Supplier","version":"1.0","type":"link"}
