Precision Ball Screw Drives

Precision ball screw drives convert rotary to linear motion with high precision, reversibility, high efficiency. For tool machines and CNC.

Nominal diameter: larger diameter carries higher axial load. Match to your load and life requirement.
Lead: lead sets displacement per revolution - higher lead gives higher speed but lower precision per step.
Precision grade: select the C-series grade (C10/C7/C5) per your positioning-accuracy requirement; higher grade = tighter tolerance.
Nut type: flange (KGF), cylindrical (KGM) or compact ball nut, based on mounting space.
Pre-loading: high-rigidity applications need pre-loaded nuts for zero-backlash and higher load capacity.

What is the main function of a ball screw drive?: To convert rotary motion into linear motion. During operation, both ends of the ball screw are connected to the motor, the ball nut is mounted in the middle, and it is linked to the component that needs linear reciprocating motion. As the ball screw rotates, it drives the ball nut in linear reciprocating motion.
What are the key features of ball screw drives?: Ball screw drives offer high precision, reversibility, and high efficiency. They are the most commonly used transmission working axis in tool machines and precision machinery.
What is the difference between a ball screw drive and a trapezoidal screw?: Ball screw drives use a ball-circulation transmission with low friction, high transmission efficiency, and good reversibility, making them suitable for high-precision linear motion applications. Selection should be based on accuracy and load requirements.
How do I choose the right precision grade for my ball screw?: Select the C-series precision grade (C10, C7, C5, etc.) based on your positioning-accuracy requirement. Higher grades offer tighter tolerances and higher precision for demanding applications.
Can you provide a selection calculation for ball screws?: Yes. We provide selection calculations based on axial load, speed, stroke and precision requirements. Contact us with your application parameters and we will recommend the appropriate specification.
