Steinmeyer, Inc. announced today a new design to the ball return for its UltraSpeed line of precision ball screws. This new design is based on a new ball return system that uses precision ball deflectors to guide the balls into a return channel spanning the whole nut length. The deflectors are precision milled and utilize a complex geometry that minimizes friction thus allowing higher speeds with less wear and better smoothness.
Steinmeyer’s UltraSpeed series of ballscrews is available in nominal diameters from 32 mm to 100 mm, and enable speed ratings up to and beyond dN=160,000. Through advanced thread grinding technology, and with lead-to-diameter ratios from 0.5:1 to 1:1, linear velocities of 4,000 inches per minute are possible at accelerations of 2 g's and higher.
