Ball Screw Driven Linear Actuators for Precision Linear Motion
DLY supplies ball screw linear actuators for automation equipment, CNC machinery, testing systems, packaging machines, robotic positioning and custom industrial motion projects. A ball screw linear actuator converts rotary motion into accurate linear movement through a ball screw, nut, guide rail, bearing support and actuator housing.
Compared with common belt drive actuators or lead screw actuators, a linear actuator with ball screw offers higher efficiency, better load capacity, smoother motion and more stable repeat positioning. For applications that require precision, thrust, rigidity and long service life, a ball screw driven linear actuator is often a better choice.
DLY can provide standard and customized ball screw linear actuators according to stroke length, load, speed, accuracy, installation direction, motor type and working environment.
What Is a Ball Screw Linear Actuator?
A ball screw linear actuator, also called a linear ball screw actuator or linear actuator ball screw system, is a mechanical motion unit that uses a ball screw and nut assembly to create linear movement.
When the motor rotates the ball screw, the ball screw nut moves along the screw shaft. The nut then drives the carriage, table or connected load in a straight line. Because balls roll between the screw shaft and the nut, friction is much lower than in a normal lead screw mechanism.
Rolling contact reduces friction and helps the actuator run smoothly under repeated motion.
High Efficiency
Suitable for automation systems that need repeatable movement and controlled linear travel.
Stable Positioning
A ball screw linear actuator assembly may include screw, guide rail, support bearing, housing, coupling and motor mount.

Main Components of a Ball Screw Linear Actuator
Ball Screw and Nut Assembly
The ball screw is the core transmission part of the actuator. It affects speed, thrust, efficiency, accuracy and service life. Common ball screw specifications may include 1204, 1605, 2005, 2510 and other models depending on the load, lead and stroke requirement.
Linear Guide Rail and Slider
A ball screw linear guide stage motion slide actuator usually combines a ball screw with a linear guide rail. The ball screw drives the movement, while the linear guide rail supports the load and controls straight-line accuracy.
Bearing Support and End Support
The bearing support fixes the ball screw and helps maintain axial rigidity. A proper fixed-end and support-end structure can reduce vibration, improve positioning stability and extend service life.
Motor Mount and Coupling
The actuator can be connected with a stepper motor, servo motor or other electric drive. For a ball screw linear actuator with stepper motor, the screw lead and motor torque should be matched carefully.
Actuator Housing and Protective Cover
The housing keeps the actuator structure aligned and protects internal parts. Depending on the working environment, the actuator can be designed as open type, semi-covered type, fully covered type or compact profile type.
How to Choose a Ball Screw Linear Actuator
For example, customers may need a 300mm, 500mm, 800mm or customized stroke linear actuator ball screw solution.
Stroke Length
For heavy load applications, a heavy duty electric ball screw linear actuator may be needed.
Load Capacity
The actuator speed depends on screw lead and motor speed. Larger lead can increase travel speed but requires more torque.
Speed Requirement
The final accuracy depends on the ball screw, guide rail, bearing support, actuator base, assembly and motor control.
Accuracy
Horizontal, vertical and inclined installation require different load and safety checks.
Installation Direction
Dust, chips, coolant, humidity and temperature may affect actuator life and protection design.
Working Environment
Ball Screw Linear Actuator vs Lead Screw Actuator
Many buyers compare linear actuator vs ball screw or ask whether a lead screw actuator is enough. A lead screw actuator is simple and low cost, but it has higher friction and lower efficiency. It is suitable for low-speed, light-duty or cost-sensitive applications.
A ball screw type linear actuator uses rolling contact between the screw and nut, so it provides smoother motion, higher efficiency, lower heat generation and better long-term repeatability. For industrial equipment, repeated positioning, higher thrust and better service life, a ball screw actuator is usually the better choice.
Ball Screw Linear Actuator vs Belt Driven Actuator
A belt driven actuator is suitable for long stroke and high speed light-load movement. However, it may not provide the same rigidity and thrust as a ball screw actuator.
A ball screw driven linear actuator is more suitable for higher thrust, better positioning accuracy, CNC axis movement, vertical lifting, precision feeding, testing equipment and industrial positioning.
