Introduction
Linear Motion Ball Screw , achieving ±0.01mm repeatability accuracy1. The module supports maximum stroke of 1050mm and speed up to 1000mm/s, compatible with 100W-400W servo motors and 57-step motors, ideal for high-speed automated production lines.
product highlights
1. Ball Screw Drive Principle
Utilizes recirculating balls within the nut to achieve rolling friction, boosting transmission efficiency to over 90%3. The screw shaft undergoes quenching treatment (HRC58-62) and C3 precision grinding to ensure micron-level positioning stability.
2. Dual Guide Rail Support Structure
Linear Motion Ball Screw Features 15mm-wide linear guides (2 per set) with dynamic load capacity up to 41400N11, combined with aerospace-grade aluminum base for optimal rigidity-weight balance.
3. Intelligent Lubrication System
Patented single-point lubrication design maintains both nut and slider, extending service life by 50%, operating temperature range from -10℃ to 60℃..

FAQ
Q: What are the conditions for achieving ±0.01mm repeatability accuracy?
A: Achieved under constant temperature (20±2℃), vibration-free environment, using C3-grade ball screws with dual guide rail parallelism calibration (error ≤0.02mm/m), combined with closed-loop servo motors. Actual accuracy may vary with load/speed/mounting rigidity – please use our load simulation software for evaluation.
Q: How to ensure parallelism of dual guide rails during installation?
A: Use a precision straightedge (0.01mm/m accuracy) with a dial indicator. Fix the primary rail to the base first, then adjust the secondary rail with locating pins or shims. Final parallelism should be ≤0.05mm over the full length.
Q: Does it support non-standard stroke customization? What is the minimum custom length?
A: Custom strokes from 50mm to 1050mm (in 50mm increments) are available. Minimum standard stroke is 100mm. For non-standard strokes, provide mounting hole distance drawings – lead time extends by 2-3 weeks.
