NSK: Heavy Duty Ball Screws with Longer Service Life

08/23/2022


The key element for the further development of the HTF-SRC series from NSK, resin, is a technology that results in more load distribution. The current increase in service life is made possible by the combination of three factors: high-precision processing machines, some of which were developed by NSK itself, simulations with the digital twin of the engine components to be developed and the use of precision measurement systems, which, among other things, have been significantly improved Larger due to correlation with processing data that provides measurement accuracy.

Advantages of the new ball screws include the ability to use smaller axle diameters in many applications, reducing engine dimensions. Take advantage of this eg b. Manufacturers of injection molding machines and servo presses that convert their machines from hydraulic drive systems to electric drive systems with servo motors and ball screws.

These solutions are especially valued by users in plastic processing. For example, there is a growing demand for high-throughput electric injection molding machines that can process more complex shapes and larger formats. Plastic processors want high-performance machines that can consistently perform highly demanding load cycles for short processing times. Shorter cycle times with higher loads in turn require the use of ball screws with a long service life.

In light of this trend, NSK has developed new Super Long Life technology for the HTF-SRC series of high-speed, heavy-duty ball screws with shaft diameters from 100 to 200 mm. Dimensions are completely identical to the previous series, so no changes are required in the design of the machine.
