Linear bearing - 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.

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.

Cassette with star grip - standard Cassette with star grip or clamping lever for locking at any position on the guide track. The clamping acts without force on the guide system. It is used for manually movable devices, clamping and holding stops, delivery of tools and processing parts. Please consult us for further information. Cassette with clamp lever Cassettes with clamping levers allow the cassettes to be locked in any position along the guideway. The clamping acts without force on the guide system. It is used for manually movable devices, clamping and holding stops, delivery of tools and processing parts. We would be happy to advise you on application and design.

In the basic version the MMC 5000 consists of a main X-axis featuring a linear air bearing (feed axis), a linear roller bearing Z-axis (infeed axis) and the milling spindle (air bearing) mounted on top of the Z-axis. The main application is face milling of optical and mechanical precision components. A Y-axis is available as an option. Another useful accessory is a second milling spindle, used perpendicular to the first one, thus allowing for the machining of two sides of a workpiece to perpendicularity in one setup. Accessories, like vacuum chucks, different milling spindles, touch probes for part thickness measurement, machine interferometers and other sensors for insitu measurement of workpiece shape and roughness, make the MMC 5000 machines an effective tool. In addition, various sensors are available for measuring of the workpiece geometry and surface quality during the manufacturing process.

Low-noise, high-quality and high-speed ball chain (patented). The WRC ball chain (patented) design offers high contact area between the balls and the chain, which helps keep the lubricant film intact, hence allowing high-speed and low-noise operations with extended service life. — Dustproof design: The completely sealed design helps prevent dust ingress and reduce lubricant loss, which leads to extended service life. — O-type arrangement: The 4-row re-circulating balls design helps achieve equal load capacity in all four directions. — Patented design for high speed/impact: The L-shaped stainless-steel reinforcement plates with bottom latches help cover and strengthen the end caps, allowing high-speed/impact operations.

Acceleration test: The acceleration test is based on a slide-crank mechanism with a flywheel as the crank. The crank imparts high acceleration and speed to the block with finite stroke. By adjusting the rotational speed of the motor, the service life of the block can be determined at different accelerations and speeds. — Both downward-bolt and upward-bolt track rails available — High rigidity structure — Reduced lubrication requirements for environmental soundness and maintenance cost saving — Built-in lubricant storage and supply system — Dustproof design Standard seals (S) — Reinforcement plate design (Patented)
