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. The two independently driven carriages in a single frame enable dynamic applications with high drive torques and short cycle times. The compact dual handling system saves valuable installation space and increases productivity, while also saving time and costs for engineering, assembly and commissioning. The new solution can be ordered as a single axis or combined with other linear axes into a multi-axis system, with the option to also 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.
The two carriages of the dual belt axis can be moved independently of each other within the compact module’s sturdy aluminum frame. Thanks to the two integrated drive chains, a variety of tasks can now be performed with only one linear axis instead of two. This saves time, costs and installation space.
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 customer’s requirements, a wide 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.
