New Shaft Coupling Solves Resonance Problems In Ball Screws

Shaft Coupling Solves Resonance  Problems In Ball Screws from Miki Pulley / Zero-Max
Miki Pulley announces introduction of its Step-Flex Coupling for direct sale to OEMs in North America. The Step-Flex is an altogether new class of shaft coupling. This design was conceived to eliminate resonance in stepper motor ball screw assemblies. The innovative two part elastomer element combination dampens vibration caused by the actuator carrier struggling to find its home position by making small adjustments in rapid sequence.

New Ball Return Design for UltrasSpeed Series

UltraSpeed image.jpg


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.

Ultra Miniature Ball Screws for Life Sciences

Ultra Miniature Ball Screws for Life Sciences


Steinmeyer, Inc. announced an important addition to its standard line of miniature precision screws – the “world’s smallest commercially available ball screw.” New ULTRAMINIATURE ball screws are available in diameters as small as 3 millimeter with choice of two pitches – 1 millimeter or 0,5 millimeter, making this product ideal for medical applications, such as precise liquid dispensing, among others. Steinmeyer now offers an extensive range of miniature screws from 16 mm diameter (with up to 30 mm pitch), down to this incredibly tiny 3 mm diameter. The screws are equipped with one of four types of ball nuts, with or without preload. And, as with all other Steinmeyer ball screws, custom lengths are available with journals machined to a control drawing.
