Robot Linear KUKA KL 250 Payload 300kg Repeatability ±0.02mm

The linear unit is a single-axis track system and is used principally as an external axis of the robot. The robot is mounted on the carriage, allowing it to be moved along a linear axis. The carriage is moved by a drive of its own. It is controlled by the robot controller. The movement range of the carriage is limited by programmable software limit switches. It is additionally safeguarded by means of mechanical stops (buffers) on the rack side.

Up to four independently driven carriages can be operated on the linear unit. Each of these carriages can additionally be coupled to one or more tender carriages. The tender carriage does not have a drive of its own and is moved by the driven carriage. The rated travel of the carriage is defined specifically for each individual unit. The interval is 500 mm.

1. Overview

The KUKA KL 250 is a high-performance linear motion unit designed to serve as an external axis for industrial robots, expanding their workspace and enhancing flexibility. With a payload capacity of 300kg and repeatability of ±0.02mm, it is ideal for applications requiring precision, such as welding, machining, material handling, and assembly.

2. Key Specifications

• Payload Capacity: 300kg
  • Suitable for heavy-duty tasks, including handling large components or multiple tools.
• Repeatability: ±0.02mm
  • Ensures consistent positioning accuracy, critical for high-precision operations like welding seams or machining parts.
• Speed: Up to 1.41 m/s
  • Enables rapid movement, reducing cycle times in high-volume production.
• Stroke Length: Customizable (up to 30.1m in some variants)
  • Adaptable to various workspace requirements, from compact cells to large-scale systems.
• Mounting Positions: Ground-mounted (other options like ceiling or side mounting may be available depending on configuration).
• Protection Rating: IP 64
  • Dust- and water-resistant, suitable for industrial environments.
• Control Integration: Mathematically coupled to the robot controller
  • No additional controller required, simplifying setup and synchronization.

3. Core Features
