KUKA Expands KR Series of SCARA Robots To Include Higher Payloads

KUKA has expanded its KR SCARA robot series to include the KR 20 and the KR 60. The new robots can handle increased payloads and are available in multiple reaches, expanding the series’ range of application possibilities. The KR SCARA series expansion aims to help customers enhance efficiency and cost-effectiveness in their production processes, addressing the challenges of modern production.

Latest KR SCARA Robots

KUKA’s newly-released four-axis robot, the KR 20, features a compact design and a payload of up to 20 kg. It is available with three reaches: 800 mm, 1000 mm, and 1200 mm. KUKA has designed the KR 20’s A1 axis with precision in mind, resulting in a rigid design for accurate and stable operation. The design also includes a cable connector plate on the top of the A2 axis, simplifying integration and installation into new and existing automation systems. 

KUKA's KR 60 SCARA robot is designed to handle even heavier payloads, up to 60 kg, and features a reach of up to 1200 mm. This makes for a 1:2 payload-to-weight ratio without compromising the robot's rigidity and accuracy. Like the KR 20, the KR 60 also features simplified installation, as the four-axis robot doesn't require any steel structure mounting or planar referencing. The KR 60 will soon be released as an addition to the KR SCARA series.

KR SCARA Series Applications

The KUKA KR series robots’ precision and speed, ISO Class 5 certification, and ESD protection make these robots suitable for use in the electronics industry, ensuring high performance, cleanliness, and safety. Potential applications include 3C, PCB assembly, soldering applications, and automotive electronics.

The KUKA KR series is also designed for use in the automotive industry, where operations are under high-cost pressure, and any downtime can lead to significant profit losses. Potential applications include small parts assembly and material handling.

Flexible Precision and Speed

In addition to the KR 20 and KR 60, KUKA's KR series has 6 kg, 12 kg, and 13 kg payload options. The 13 kg is exclusively available as a hygienic oil version, meaning it is specifically developed to meet the needs of the food industry. This is accomplished by using food-grade lubricants within the robot, ensuring that the robot can meet the standards where hygiene is paramount. Like its new releases, earlier KR SCARA robots focus on high precision, speed, and flexibility.
