Efficient lightweight axis made of carbon fiber

Today a good command of English is self-evident. How about your knowledge of technical terms? At regular intervals handling publishes interesting news and translates some vocabulary.

Components made of carbon fiber are making many advances in racing and automotive engineering. With the CFK-axis system CLD, Schunk is now showcasing for the first time, a standardized linear axis made of carbon fiber. It is the lightest directly driven linear axis on the market. Compared with aluminum profiles, the weight of the profile reduces by 58 per cent. For multi-axis handling systems, where complete Z- or Y- axis are moved, the lightweight design ensures efficiency and helps the axes to accelerate, saving a lot of energy in the process. The innovative linear module from Schunk offers many advantages. The carbon composite makes the axes extremely light, yet stable. Due to the higher E-module of the material, they dispose of a higher bending and torsional stiffness than aluminum profiles. The high dampening reduces vibrations and results in a higher dynamical stiffness. If the material heats up during operation, it stays dimensionally stable. These are the best pre-conditions for micron-precise use of inspection and handling applications. The efficient light-weight axes give an edge to the users in respect to cycle times and precision. pb

Needle roller bearings for the Shinkansen

With a range of components for the braking system of the new Shinkansen E5, the Rail Sector Management of Schaeffler Group Industrial has succeeded for the first time in being represented in the Japanese high speed train. The new series of the Shinkansen will start running between Tokyo und Shin Aomori from December 2010. The increase in travel speed along this line from 275 km/h to 320 km/h required a new high performance braking system, which was developed by Knorr-Bremse. The axle-mounted brake calipers in the system are fitted with needle roller bearings and drawn cup needle roller bearings, inner rings, axial bearing washers, bearing washers and axial needle roller and cage assemblies from INA. The drawn cup needle roller bearings are protected against corrosion by the Corrotect N coating. This is an extremely thin surface coating free from chromium VI, developed by the Schaeffler Group. It protects products and components against corrosion and especially against the formation of rust on the running surfaces under the seals, which could be caused by condensation, rainwater or contaminated water. pb
