MOONS's ball screw linear stepper motors are designed based on the know-how technology of hybrid stepper motors, ball screws, and nuts. Provide high torque, high precision, and high efficiency to fit the application needs of designers. In the case of external linear actuators, the lead screw is permanently attached to the motor shaft and turns with the shaft when the motor is energized. If an externally threaded nut is mounted on the lead screw and secured against rotating by an external guide, the threaded nut moves along the lead screw.
The combination of motor styles, motor sizes, ball screws, and nuts, gives the freedom to use motors of different form factors to exactly fit in the application. And, it provides the best performance with any drive and power supply.

High mechanical efficiency

The Ball screws of Linear stepper Motors have outstanding transmission efficiency of over 90%, incomparably higher than lead screws. Their required torque is just less than a third of what the lead screws require. Therefore, it is easier to transfer a linear motion into a rotary motion.

High accuracy

The ball screw of the linear stepper motors adopts the Gothic arch groove profile, and its axial clearance can be adjusted at very fine intervals and can be rotated slightly. In addition, by giving a preload to the screw, the axial clearance could be adjusted to 0 to achieve higher accuracy. The repetitive positioning accuracy of the ball screw linear stepperping motor can reach ±0.02mm, the screw diameter is up to 10mm, and the lead starts from 0.01mm/rev. Various stroke lengths, lead wires, and end treatments of the screw rods can be customized.

High rigidity

The Ball screws of linear stepper motors maintain excellent durability achieved by carefully selected materials, proper heat treatment, and machining with advanced production technologies. Ball screws are generally manufactured to maintain the minimum standard hardness at 58 HRC with the materials listed on the right table.The overall hardness far exceeds the combination of threaded screws and nuts.

For safe use, you need to pay attention to the following points:


When using the ball screw products, lubricant should be required. If lubricant is not applied with, the problem such as increase of torque and shortened life occurs. Applying lubricant can minimize temperature increases, a decline of mechanical efficiency due to friction, and deterioration of accuracy caused by wear.

Fall carefully

Since a ball screw has a low friction factor, its shaft or nut could potentially fall off due to its own weight. When you move the product, please be careful not to slip due to your own weight.

Do not disassemble a nut.

When balls have been dropped off the nut or the nut has been removed from a shaft, do not attempt to reassemble them yourself and return them to our company for repair.(In this case, repairing charges are required.)If it necessary to disassemble the nut by yourself, Please consult with our technical department first.

Pay careful attention to mounting accuracy.

A moment load caused by misalignment of a ball screw, bearing, guide, nut, and housing and improper angularity may result in malfunction, extraordinary noise, abnormal vibration, shorter product life as well as breakage of screw shaft due to rotating bending fatigue. Be careful with such defects because they may lead to a serious accident.

Working Temperature

Normally,The BSM Series work temperature range is 0~60 ℃ .If it necessary to work beyond the recommended temperatures, Please consult with our technical department first.
