Mini Lead Screws

Miniature lead screws have become increasingly popular in recent years due to their ability to provide high precision linear motion in compact spaces.As leading precision lead screw manufacturer,our miniature lead screw diameter from 2mm to 12mm.

Mini lead screws are made up of several components,including screw shaft & nut.The screw shaft is typically made of materials such as stainless steel or carbon steel,while nut is made of materials such as brass bronze or plastic.

Micro lead screw is ideal for use in miniature linear motion systems such as microscopes and precision stages.These small diameter lead screws can also be integrated with miniature stepper motors for precise positioning in robotics and automation applications.
