Introducing the Rexroth CKR-280 Dual Belt Linear Axis — A Breakthrough in Heavy-Payload Linear Motion
In a major leap for industrial automation, Bosch Rexroth has unveiled the new Rexroth CKR-280 Dual Belt Linear Axis, a compact yet heavy-duty solution designed to handle ultra-high payloads with exceptional speed and precision. This linear motion system addresses the growing requirements of high-performance applications in battery production, machine tool automation, intralogistics and multi-axis systems.

High Payload, High Dynamics
The standout feature of the CKR-280 is its dual-carriage design inside a single frame: two independently driven carriages each capable of moving up to 385 kg, for a combined payload capacity of up to 770 kg. This dual axis integration enables handling two loads or two process stations in one unit — effectively replacing two separate systems and thus optimizing space, cost and engineering overhead.
At the same time, the CKR-280 is built for impressive dynamics: speeds up to 5 m/s, accelerations up to 5 g, and repeatability of ±0.05 mm. The drive torque is also robust, up to 250 Nm, enabling heavy loads to be moved with agility.
Efficiency Through Compact Integration
By combining two carriages into one compact module, the CKR-280 dramatically reduces installation footprint and simplifies system layout. Bosch Rexroth emphasises that “the functions of two linear axes into one linear system” help lower engineering, assembly and commissioning time. The module supports online configuration up to 5.50 m travel length, and longer ranges on request, allowing flexible adaptation to single-axis or multi-axis systems.
Smart Applications & Industry 4.0-Ready
The CKR-280 is ideally suited for next-generation manufacturing where precision, high throughput, and automation converge. In battery manufacturing lines, for example, the dual carriage can load one side while processing occurs on the other — reducing idle time and boosting throughput. In machine tool automation, one carriage can serve as part-feed while the other handles unloading, enabling parallel operation and faster cycle times. Its repeatability and dynamic performance make it well-matched for high-precision machining.
For intralogistics and material handling, the compact dual axis helps manage heavy pallets, modules or tooling with fewer components, lower footprint and higher speed. The ready-to-configure travel length and dual-drive option support flexible layouts and modern manufacturing demands.
Engineering Benefits & Reduced Total Cost
From an engineering perspective, the CKR-280 simplifies system design by reducing the number of axes and drives required. Since two carriages operate independently in a single frame, fewer sub-systems are needed, lowering component count, wiring, commissioning time, and maintenance. The integration into Bosch Rexroth’s online e-tool chain means the module can be configured and ordered quickly.
The enhanced rigidity of the size-280 frame supports high moment loads and improves stability during fast motion, giving greater positioning accuracy and machine reliability.
