June 26, 2025 - Bosch Rexroth is expanding its CKR series of compact modules with an innovative dual belt axis for dynamic handling with a total load capacity of up to 770 kg. The new CKR-280 heavy-duty axis combines the functions of two linear axes into one linear system. Two, independently driven carriages in a single frame enable dynamic applications with high drive torques and short cycle times. The compact, dual-handling system reduces valuable installation space and increases productivity, while saving time and costs for engineering, assembly and commissioning. The new solution can be utilized as a single axis or combined with other linear axes into a multi-axis system, with the option also to include a drive package.
Whether in battery production, intralogistics or machine tool automation, many industries are increasingly seeking compact handling solutions that can move large payloads with high dynamics. With the new dual belt version of the CKR compact module series in size 280, Bosch Rexroth offers a space-optimized, heavy-duty axis that can handle two payloads up to 385 kg each and drive torques up to 250 Nm. To enable fast and easy engineering, the compact modules can be configured online in lengths up to 5.50 m. Bosch Rexroth can also deliver longer travel ranges on request.
High accelerations of up to 5g and a maximum speed of 5 m/s provide the optimal conditions for short cycle times with high precision and a repeatability of +/- 0.05 mm. Depending on the requirements, a variety of travel profiles can be implemented independently. After its market launch, the CKR-280 heavy-duty axis will also be integrated into the e-tool chain as a new size for single-axis and multi-axis systems.
