Miniature Ball Screws include 3 mm size.

Press Release Summary:



ULTRAMINIATURE ball screws are offered in diameters as small as 3 mm, with choice of 1 mm or 0.5 mm pitch. Made from standard tool steel, screws are hardened and precision ground to meet ISO tolerances from T0 to T5. Nut types include: Series 1112 cylindrical with attaching thread, Series 1214 cylindrical with fitting key, and Series 1412 with flange. All include preload option. Series 1510 spring-preloaded, double nut compensates for torque variations.

New Ultraminiature Sizes Available in Precision Ground Ball Screws


Bedford, MA, March 26, 2003 -- Steinmeyer, Inc. announced an important addition to its standard line of miniature precision screws - the world's smallest 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. 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. By using Steinmeyer's internal ball deflector returns instead of external tubes, the nuts offer smooth low noise operation in a compact size. Several standard lengths are included in the production program, complete with finished ends. And, as with all other Steinmeyer ball screws, custom lengths are available with journals machined to a control drawing. The screws are manufactured from standard tool steel, hardened and then precision ground to meet ISO tolerances from T0 to T5. Stainless steel material is available as an option.

For maximum application flexibility, Steinmeyer miniature screws are offered with a choice of four nut types:

- series 1112, a cylindrical single nut with convenient attaching thread, available with play or preloaded using oversized balls.

- series 1214, a compact cylindrical single nut with fitting key, available with play or preloaded using oversized balls.

- series 1412, a single nut with flange, available with play or preloaded using oversize balls

- series 1510, a spring preloaded double nut, that effectively compensates for torque variations due to inaccuracies in the ground thread. The result is extremely smooth motion with near constant idling torque - a critical requirement in many scanning applications.

Applications for miniature ball screws include semiconductor production machines, inspection equipment, microscope stages, fiber-optic assembly mechanisms, medical devices, miniature robotics, and analytical equipment.
