Rotary tables - Import export

Hydrostatic bearings are characterized by practically frictionless movement. The corresponding linear guides are free from stick-slip effects and there is practically no wear on the guides. Gases (mostly air) or liquids (mostly oil) can be used as the carrying medium. Air-bearing guides are ideal, for example, for clean room applications or at high sliding speeds. If oil is used as the carrying medium, higher carrying forces can be achieved with the same size and better damping properties. Various designs are available, which can be customized at any time to meet special requirements in terms of installation space, load capacity, guide length / table diameter, drive type, position measuring system, etc.

Bearing assemblies with direct drive are suitable for applications where high performance and low space requirements are important criteria. The integration of the drive into the bearing housing means that wear-prone assemblies for transmitting drive power, such as toothed belts, shafts or chains, can be dispensed with. This reduces the required drive energy and also benefits more accurate positioning.

For our bearing assemblies and linear systems, we use high-quality lubricants as standard that are suitable for most applications. Special operating conditions require special lubricants. Standard and special greases are available in the respective container sizes from us as accessories. They can be used when our bearing elements are used for the first time or for relubricating slewing rings.

Within the HERMLE range of models, the C 250 is an entry-level model into the world of 5-axis & 5-sided machining. Nevertheless, the “large” models are in no way inferior. Thanks to the large swivelling range of the workpieces in the working area, the utilisation of the complete traverse range and the large collision circle between the table side walls, the C 250 offers the largest working area relative to the installation area. The C 250 is designed for daily use – maximum user-friendliness thanks to pivotable control panel and minimum table distance from the operator and optimum loading height with option ofloading by crane. Maximum precision thanks to the HERMLE swivelling rotary table concept. The table variants of the C 250 therefore stand for the highest quality and optimum use of material – from the cast housing to the installed gear motors: Made in Germany – made in Gosheim.

The DDA Direct Drive Motor is a rotary actuator that directly drives a rotary table with a motor without using any speed reducing mechanism such as a belt or reduction gears. Eliminating the speed reducing mechanism explains why high speed and excellent response can be attained with such a compact frame. The series includes models designed for high torque and high payload up to 90 or 270 kg. This makes it very easy, for example, to integrate rotary indexing tables in an automation system.
