Bosch Rexroth is expanding its CKR series of compact linear motion modules with an innovative dual belt axis, offering dynamic handling and a total load capacity of up to 770 kg. The new CKR-280 heavy-duty axis integrates the functionality of two linear axes into a single system. Its two independently driven carriages in a single frame enable dynamic applications with high drive torques and short cycle times.
Two drive chains, one axis
This is ideal for applications in battery production, intralogistics and machine tool automation. Many industries are increasingly seeking compact handling solutions that can move large payloads with high dynamics. With the CKR compact modules in size 280, Bosch Rexroth offers a heavy-duty axis that optimises space and can handle two payloads of up to 385 kg each, as well as drive torques of up to 250 Nm. The two carriages can move independently within the sturdy aluminium frame of the compact module. Thanks to the two integrated drive chains, a variety of tasks can now be performed using just one linear axis instead of two. This saves time, costs and installation space.
The compact modules can be configured online in lengths of up to 5.50 metres to enable fast and easy engineering. Bosch Rexroth can also deliver longer travel ranges on request. High accelerations of up to 5 g and a maximum speed of 5 m/s provide optimal conditions for achieving short cycle times with high precision and repeatability of ±0.05 mm. A wide variety of travel profiles can be implemented independently depending on the customer’s requirements.
