Unveiling ball screws, bearings and linear guides from NSK
Among the exhibits by NSK at EMO are numerous products for machine tools from the company's comprehensive portfolio.
The highlights at the booth of global manufacturer, NSK, include the company's recently introduced range of DIN-standard ball screws and a new series of high-durability precision ball screws, optimised spindle bearings for precision and speed as well as a series of linear roller guides equipped with dustproof seals. The DIN-standard ball screws offer high-speed and high-load capacity with low noise. The TF bearing steel is said to achieve up to 1.4 times the dynamic load rate.
NSK’s latest range of precision ball screws have a newly developed surface processing technology that reduces wear, which provides maintenance-free operation for longer intervals. A special surface texture is applied to the raceways to greatly enhance oil film formation. It is normally difficult for a satisfactory oil film to form during low-speed, short-stroke and oscillating-type operations. Here, these ball screws, ideal for machining centres that perform high-accuracy operations like mould and die machining, as well as EDM machines, are three times more resistant to wear than standard NSK products, the company notes.
Another highlight, the interchangeable ball screw for automated transfer (pick and place) systems, in which the shaft and nut are individually picked to allow for random matching, provide a C7-accuracy grade.
Other highlights include NSK's newly introduced single-row cylindrical roller bearings with the designation “Robustride” and the company's new RA series of linear roller guides with highly dustproof V1 seals and V1 bottom seals, which help improve the operating life and reliability of machine tools.
At EMO, the company booth will be in Hall 7, Booth B34.
