This precision coupling features a dual clamp hub bore design with \u003cstrong\u003e11 mm\/11 mm bore diameters\u003c\/strong\u003e, enabling secure shaft attachment on both driving and driven axes. Constructed with an \u003cstrong\u003ealuminum hub\u003c\/strong\u003e and a medium-hard \u003cstrong\u003eelastomer insert\u003c\/strong\u003e (shore 98A typical), it balances torsional flexibility with torsional stiffness for smooth torque transfer. The coupling’s compact \u003cstrong\u003eSize 20\u003c\/strong\u003e footprint and lightweight construction simplify integration into space-constrained servo and motor systems without compromising performance.\u003c\/p\u003e\n\n\u003cp\u003eThis coupling’s technical specifications ensure consistent operation under dynamic conditions: it supports a \u003cstrong\u003etorque capacity of approx. 3.5 Nm\u003c\/strong\u003e and maximum rotational speeds of \u003cstrong\u003eup to 10,000 rpm\u003c\/strong\u003e. The \u003cstrong\u003eoverall length of approx. 34 mm\u003c\/strong\u003e and \u003cstrong\u003eouter diameter of approx. 28 mm\u003c\/strong\u003e minimize overhang and reduce system inertia. Clamping is achieved via \u003cstrong\u003eM4 clamping screws\u003c\/strong\u003e, delivering backlash-free engagement while facilitating rapid assembly and disassembly. Designed for use across a broad \u003cstrong\u003etemperature range from –30°C to +90°C\u003c\/strong\u003e, the coupling withstands thermal cycles typical of factory automation. Additional critical specifications include its classification as an \u003cstrong\u003eelastomer coupling\u003c\/strong\u003e and the use of a precision clamp hub \u003cstrong\u003ebore type\u003c\/strong\u003e for reliable torque transmission.\u003c\/p\u003e\n\n\u003cp\u003eOperational features of the 8ECR0020.1111C-0 coupling focus on durability and maintenance efficiency. The medium-hard elastomer insert absorbs minor misalignment and dampens vibration, extending bearing life and reducing noise. The aluminum hub material provides excellent corrosion resistance and mechanical rigidity for continuous operation in harsh factory conditions. Maintenance intervals are extended due to the insert’s resistance to fatigue and environmental factors, eliminating the need for frequent realignments or replacements. The compact form factor and low mass reduce the load on motor bearings and permit higher dynamic acceleration and deceleration profiles.\u003c\/p\u003e\n\n\u003cp\u003eSystem integration is streamlined by the coupling’s universal clamp hub interface, facilitating direct compatibility with standard motor and gearbox shaft diameters. Use cases include precision servo motors, stepper drives, gearboxes, and rotary encoders within automated assembly lines, packaging machinery, and CNC tooling centers. The robust design and broad operating temperature window make the 8ECR0020.1111C-0 particularly suitable for applications in automotive manufacturing, food processing, and material handling systems where reliability under thermal and mechanical stress is essential.\u003c\/p\u003e","brand":"B \u0026 R Automation","offers":[{"title":"Unused Surplus","offer_id":51690047930669,"sku":null,"price":1514.23,"currency_code":"USD","in_stock":true},{"title":"Refurbished","offer_id":51690047963437,"sku":null,"price":1376.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/7696\/9517\/files\/CM16_Motor_Cable_Series__7044952c-3ee5-46de-81ee-a0ad931b892c.webp?v=1760038990","url":"https:\/\/servosupplier.com\/products\/8ecr00201111c-0","provider":"Servo Supplier","version":"1.0","type":"link"}
