Introducing the New Rexroth CKR-280 Dual Belt Linear Axis: Revolutionizing High-Payload Linear Motion
Bosch Rexroth is setting a new benchmark in linear motion technology with the launch of its CKR-280 Dual Belt Linear Axis, a powerful and compact module designed specifically for high-payload industrial automation. This latest innovation brings together dual-carriage dynamics, high speed, precision, and exceptional load handling, ideally suited for modern machine tools, battery production lines, and heavy-duty multi-axis systems.
Why the CKR-280 is a Game-Changer
The Rexroth CKR-280 is a unique linear motion solution featuring two independently driven carriages in the same frame, each capable of carrying up to 385 kg. Combined, the system supports a total payload of 770 kg, making it one of the most capable compact modules for demanding high-load applications. Control.com+1
Thanks to its dual-belt configuration, the CKR-280 achieves high acceleration (up to 5 g) and travel speeds of up to 5 m/s, enabling ultra-fast cycle times without compromising stability or repeatability. Control.com According to Bosch Rexroth, the system offers precise repeatability at around ± 0.05 mm, which is exceptional for such heavy-duty motion axes. Control.com
Compact, Flexible, and Efficient
One of the standout advantages of the CKR-280 is its compact footprint. By combining two carriages in a single frame, the design minimizes installation space—an especially attractive feature for multi-axis or tightly packed machine setups. Control.com The axis is configurable to lengths up to 5.5 m, giving engineers flexibility for bespoke or large-scale motion systems. Control.com
Moreover, the CKR-280 is fully compatible with Bosch Rexroth’s digital engineering toolchain, including online configuration tools and e-tools that simplify selection, delivery, and system scaling. Control.com This ensures faster design cycles and smoother integration into existing automation ecosystems.
Applications That Benefit the Most
Battery production: With its dual carriage system, the CKR-280 allows for synchronized or independent motion—making it ideal for loading/unloading battery components, reducing idle times, and increasing throughput. Control.com
Machine tools: In CNC or machining applications, one carriage can handle a workpiece while the second handles a finished part, enabling parallel processing and better productivity. Control.com
Heavy-duty multi-axis gantries: The high load capacity combined with tight repeatability makes the CKR-280 ideal for Cartesian robots and gantry systems that need both strength and precision.
Intelligent and High Performance
The CKR-280 isn’t just about brute force — it’s engineered with intelligence. It integrates with Bosch Rexroth’s motion control systems and can be used with their ctrlX AUTOMATION toolkit, enabling synchronized control and high-level diagnostics. Bosch Rexroth Global+1 Such integration supports smart manufacturing and predictive maintenance, helping reduce downtime and optimize performance across the production line.
Energy Efficiency & Sustainability
Despite its heavy-load capabilities, the CKR-280 is designed with energy efficiency in mind. The dual-belt drive not only delivers high torque but also ensures smooth, low-loss motion, reducing power consumption and minimizing heat generation. This aligns with Bosch Rexroth’s commitment to sustainable automation.
Built for Easy Integration
Engineers will value how the CKR-280 fits into the larger Rexroth ecosystem. It is compatible with existing Rexroth compact modules, linear guides, and control systems, making it a plug-and-play option for upgrading or expanding automation solutions. The e-tool configurator speeds up design iterations, and global supply support ensures the modules can be sourced reliably. Control.com+1
