Fast high-load ball screws
05 March 2018
With linear speeds of up to 3 m/s (twice as quick as conventional balls screws in this type of application), NSK is introducing what is claimed to be the world's fastest high-load ball screw.
The latest additions to the HTF-SRE and HTF-SRD series mean that the clamping and dynamic axes of all-electric plastic injection moulding machines can now benefit from faster acceleration and higher final speed.
In the HTF-SRE series, NSK previously only offered relatively large spindle diameters of 140 to 200 mm. Now, for the latest injection moulding machines with very high dynamic performance requirements, small and medium diameters (starting from 50 mm) have been added.
The HTF-SRD series, which is suitable for the clamping units of plastic injection moulding machines, has been expanded with versions featuring larger leads. Machinery designers can now utilise high-load ball screws with top feed speeds of 2 to 3 m/s, which in turn allows end users to benefit from shorter cycle times and increased productivity.
