Epson G20 SCARA Robots

850 | 1000

Long Reach, Heavy Payloads, and High Performance

  • Super Heavy Payloads with High Performance
  • Tabletop, Ceiling and Wall Mount Models
  • Arm lengths of 850 and 1000mm
  • ISO Clean & ESD Compliant Models
  • IP54 and IP65 Washdown/Dustproof Models

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.
