Linear guides for automation and heavy duty applications
CRD Devices now offers a number of different linear guides to meet the needs of different applications. Products include the Hiwin EG series of low profile ball type linear guides for automation applications, and the new Hiwin RG series of roller type guideways for heavy and super-heavy loads demanding the highest levels of rigidity.
>These two ranges of linear guides are available in standard lengths from 100mm to 4000mm, and rails can be combined to provide travel lengths of several kilometres where required. The linear guides are provided in several accuracy classes, from high precision right up to ultra precision that guarantees tight dimensional tolerance and the greatest accuracy of running parallelism.
>The design of the EG series offers a low profile of 24-48mm, high load capacity (up to 33kN dynamic load, 64kN static load), and high rigidity. It also features an equal load rating in all four directions and self-aligning capability to absorb installation-error, allowing for higher accuracies. Additionally, the lower assembly height and the shorter length make the EG series more suitable for high-speed, automation machines and applications where space is limited.
>Applications for the EG series include automation devices, high-speed transportation equipment, precision measuring equipment, semiconductor manufacturing equipment and woodworking machinery.
>For the heaviest loads and increased operating life, the new RG series features a roller as the rolling element instead of steel balls. The roller series offers super high rigidity and very high load capacities - up to 275kN dynamic, 572kN static. The RG series is designed with a 45-degree angle of contact. Elastic deformation of the linear contact surface, during load, is greatly reduced thereby offering greater rigidity and higher load capacities in all four load directions. Further, the unique design of the circulation path allows the RG series linear guideway to offer smoother linear motion.
>RG series linear guideways are classified into non-interchangeable and interchangeable types - interchangeable types of blocks and rails can be freely exchanged and still maintain p-class accuracy. Because of this strict dimensional control, the interchangeable type linear guideways are ideal when rails do not need to be matched for an axis. Applications for the RG series include CNC machining centres, heavy duty cutting machines, CNC grinding machines, injection moulding machines, plano millers and electric discharge machines.
>CRD Devices also have the largest range of Hiwin linear actuators from stock. As well as actuators CRD Devices supply screw jacks, ball screws, linear motors, linear bearings, solenoids and electromagnets.
