UR18g-950 Compact Heavy-Duty Cobot

Q: What are the UR18g-950's payload and reach?

The Universal Robots UR18g-950 has an 18 kg (39.7 lb) payload, the highest in the g-Series, and a 950 mm (37.4 in) reach. It weighs 39.2 kg (86.4 lb) on a Ø204 mm footprint, repeats to ±0.05 mm and reaches 4 m/s at the tool center point. Universal Robots calls it the compact heavy-duty cobot and lists no separate extended payload.

Q: Can the UR18g-950 be mounted on a gantry?

Yes. Universal Robots says the UR18g-950 is light enough for easy mounting on most standard gantry systems, and its data sheet rates the arm for mounting in any orientation. With an 18 kg payload for larger end effectors and speeds up to 4 m/s, Universal Robots positions it for fast pick-and-place cells where reducing cycle time is crucial.

Q: Does the UR18g-950 replace the UR18?

Yes. Universal Robots lists the UR18g-950 as the successor to the UR18, as part of the g-Series robot family released in 2026 on the Gen 7 platform. It adds 1 Gb Ethernet, 24/48 V power and safety-rated inputs at the tool flange. Universal Robots says the UR18 remains fully supported, with service, spare parts and software updates continuing.

Q: Can the UR18g-950 run in dusty or washdown areas?

Yes. Every g-Series arm, including the UR18g-950, is rated IP65 for dust and water protection, and Universal Robots designs the family for dirty and washdown environments. It uses fewer components and an enclosed joint design built on the proven UR joint architecture. In the Gen 7 system, the CB7 Core controller and TP7 Core teach pendant are rated IP54.

Q: Who sells and supports the UR18g-950 in New Jersey?

The Knotts Company in Berkeley Heights, NJ, a Universal Robots partner since 2017, sells and supports the Universal Robots UR18g-950 for manufacturers in New Jersey, New York and Eastern Pennsylvania. Knotts can help you size the arm to your payload, reach and cell layout before you buy. Contact automate@knottsco.com or (908) 464-4800.
