Epson G20 SCARA Robots - 850mm

Long Reach, Heavy Payloads, and High Performance

  • Super Heavy Payloads with High Performance
  • Tabletop, Ceiling and Wall Mount Models
  • ISO Clean & ESD Compliant Models
  • IP54 and IP65 Washdown/Dustproof Models
  • Also available in 1000mm arm length

Epson G20 SCARA robots are the heavyweight champion when it comes to SCARA robots performance under heavy payloads. With Epson's new high rigidity arm design, G20 robots can handle up to 20Kg payloads at high speeds. Most robots available today that promise higher payloads do so with extremely reduced cycle times and poor duty cycles. Epson G20 SCARA robots were designed for heavy payloads while running 24/7 at high speeds. G20 SCARA's are perfect for higher payload applications such as machine load/unload, palletizing, mechanical assembly, pick and place applications, food handling and hundreds of other applications. With applications running in demanding industries such as Automotive, Medical, Semi Conductor, Food, Pharmaceutical, Consumer, and many others, Epson G20 SCARA's deliver the high performance required for todays demanding applications when other SCARA robots can't.

G20 SCARA arms are available in 850 and 1000mm lengths with either 180 (150 clean) or 420 (390 clean) Z-Axis lengths. They are also available in table top , wall or ceiling mount configurations. Clean/ESD, Washdown and Dustproof models are also available. That makes for a lot of choices to make sure you get the right robot for your next application.

G20 SCARA robots incorporate the new Max-E work envelope design. With Max-E, Epson G-Series SCARA robots are able to do jobs that previously required 50mm or more of additional reach. Smaller footprints are what make this happen and that translates to less factory space requirements and less overall factory costs.

The G20 SCARA lineup handles the heaviest payloads while still providing high performance motion and speed. G20 high rigidity arms combined with our PowerDrive servo technology yield high performance results that customers have come to expect from Epson. Add to that industry leading ease of use, and it's no wonder that the G20 is the robot of choice for heavyweight SCARA applications.

High Performance
  • Best in Class Motion Range with Max-E design allows maximum footprint efficiency
  • Champion Cycle times of 0.369 seconds improve total part throughput
  • Outstanding Accel/Decel Rates (even with heavy payloads) with smooth start/stop motion
  • Top speeds of 11,500 mm/sec gets parts moved fast and precisely
  • Low residual vibration due to unique high rigidity arm design

High Payload AND High Performance
  • Payloads up to 20Kg with Rated Payloads of 10Kg
  • Maintain higher duty cycles and overall performance vs. competitive models

Wide Variety of Arms and Configurations
  • Arm lengths of 850 and 1000mm provide customers the ability to choose the best arm for the job
  • Tabletop, Ceiling and Wall Mount Models
