These miniature lead screws are among the smallest commercially available, with diameters as small as 0.5mm. That’s just under the size of a grain of sugar!
Miniature lead screw in action
The example lead screw in the video above is about 1mm in diameter. Actuating this miniature lead screw is super smooth. Indeed it’s so smooth that it can be actuated at the tip of a pin. Additionally, this nut and screw is made from 440 and 420 stainless steel, making for a high degree of cleanliness.
- Diameter: 1.0mm
- Pitch: 0.1mm
- Material: 420J2/440C
Taking a closer look
Below are some examples of miniaturized lead screws to give a better sense of what can be made. These micro lead screw diameters generally range from 4.0mm down to 0.5mm, with pitch sizes ranging from 5mm down to 0.15mm. Lengths and nut geometry for these screws are made to your specifications.
More about miniature lead screws
These miniature lead screws are commercially available from 4.0mm down to 0.5mm in diameter. Furthermore, with highly developed processing and material selection, these screws have a backlash of under 2μｍ. As a result, they work incredibly well for micro applications, where a high degree of accuracy and precision are a must. Additionally, they’re built to last, tested over 80km (50 miles) under continuous load of 2.5kg.
In need of smaller sizes?
Do you have a legitimate need for lead screw sizes smaller than 1mm in diameter? Challenge accepted! As technology advances in the medical sector and others, miniaturization has become a key area of need. Hence, these micro lead screws are part of a platform, paving the way for advancements in drug delivery, automated surgery, and more.
