Ball Screw Stepper Motor integrates stepper motor and precision ball screw together. It directly converts motor rotation into high-precision linear reciprocating motion. It eliminates extra mechanical parts such as couplings and separate screw supports, featuring compact structure, high positioning accuracy and low friction. It is widely used in precision lifting stages, biotech pipetting systems, 3D printing, electronic component pick-and-place and optical fine-tuning equipment. We supply Ball Screw Stepper Motor in multiple flange sizes. Custom screw lead, stroke, closed-loop encoder and power-off brake are available.
Precision Preloaded Ball Nut to Eliminate Transmission Backlash
This Ball Screw Stepper Motor adopts preloaded ball nut structure to remove clearance of ball pair. Reverse positioning error is minimized during reciprocating linear movement and ensures high-precision repeated feeding. It is a widely used ball screw integrated stepper motor for precision linear stages.
Optional Dust Cover to Protect Ball Circulation Raceway from Contamination
Telescopic dust boot can be equipped to block dust and debris from entering ball raceway, reducing wear of steel balls and screw. It fits workshop environments with fine particles such as electronic assembly and powder inspection.
Hardened Screw Surface for Excellent Wear Resistance & Deformation Resistance
The screw thread surface is quenched and hardened to raise surface hardness. It reduces wear and plastic deformation under long reciprocating motion and maintains stable linear feeding accuracy after continuous operation.
Low Operating Friction to Reduce Motor Power Consumption and Heat
Ball rolling friction replaces sliding friction and greatly cuts transmission resistance. The motor bears lighter load under the same thrust output with less heat generation, ideal for automated inspection machines requiring long continuous feeding.
Fast Response with No Start-Stop Lag and Good Dynamic Following Performance
The ball screw features high transmission rigidity and minimal clearance. It can start and stop rapidly after receiving pulse commands, suitable for precision motion applications requiring frequent position switching and short-distance high-speed micro feeding.
Rich Customization & Complete Set Delivery Available
Our Ball Screw Stepper Motor supports custom screw stroke, lead, anti-rotation structure, encoder and power-off brake. You can order the integrated ball screw motor alone or get packages with stepper motor driver for one-stop purchase and shorten sample validation lead time.

Q: Can Ball Screw Stepper Motor run continuously with high-speed reciprocating feeding?
A: Yes, but the maximum linear speed must be controlled. High speed brings higher ball impact and noise. Match screw lead and motor speed for high-speed applications, reduce travel speed if necessary.
Q: How does the preload of ball screw nut affect Ball Screw Stepper Motor?
A: Preload eliminates screw backlash and improves positioning accuracy. However, excessive preload increases friction, raises motor load and temperature. Balance accuracy and load during selection.
Q: Will low ambient temperature affect the performance of Ball Screw Stepper Motor?
A: Low temperature changes viscosity of screw grease and increases motion resistance, which may lead to stuttering movement. Special low-temperature grease is required for cold environments, and motion resistance should be evaluated in advance.
Q: How to extend service life of Ball Screw Stepper Motor when operating under long reciprocating motion?
A: Keep the screw surface clean to prevent dust and debris entering the ball circulation groove. Operate within rated thrust with proper safety margin. Check lubrication regularly for continuous long-time operation.
Q: What happens if radial side load is applied to Ball Screw Stepper Motor?
A: Ball screw stepper motor is designed for axial thrust. Excessive radial load will damage ball circulation system, cause premature wear and affect positioning accuracy. Avoid side force during installation.
