C7 Precision Large Lead Ball Screw for Automation

As a specialized manufacturer, we developed the Maitu C7 Precision Large Lead Ball Screw for Automation specifically to address this market demand. Crafted from high-quality GCr15 bearing steel and subjected to rigorous heat treatment processes, this product achieves a hardness of HRC 58–62, thereby ensuring exceptional wear resistance and structural integrity. Our advanced cold-rolling technique not only boosts production efficiency but also effectively controls manufacturing costs, resulting in a cost-performance ratio that far surpasses that of products produced via traditional grinding processes.

Its large-lead design—featuring a diameter range of 32mm to 63mm and a lead range of 40mm to 70mm—enables automated equipment to achieve substantial linear displacement with fewer motor rotations, thereby significantly enhancing operational speed and production efficiency. Concurrently, its C7 precision rating (with a lead error of ≤0.023mm/300mm) is fully sufficient to meet the positioning accuracy requirements of general-purpose automated machinery, avoiding unnecessary precision redundancy while striking a perfect balance between performance and cost.

High-speed large-lead efficiency: The lead specifications range from 40mm to 70mm. Under the standard motor speed (3000RPM), the maximum linear speed can reach 3.0m/min, which is 2.5-3.0 times that of standard small-lead (10-20mm) ball screws, significantly improving the operation efficiency of automation equipment.

Cold-rolled process advantage: Advanced high-efficiency cold-rolled technology, production efficiency is more than 3 times that of grinding process, which can realize large-scale batch production, effectively control product costs, and have obvious price advantages in the automation component market.

Excellent load capacity and rigidity: Optimized nut structure and high-strength material selection ensure excellent load capacity. The dynamic load capacity is 75-210kN, which can meet the transmission needs of most general automation equipment and avoid deformation during operation.

Strong environmental adaptability: Equipped with integrated dust-proof and anti-corrosion seals, it can adapt to the general industrial workshop environment, prevent dust and impurities from entering the raceway, and ensure the stable operation of the equipment.

FAQ

Q: Is the C7 Precision Large Lead Ball Screw suitable for high-precision automation scenarios?

A: The C7 Precision Large Lead Ball Screw for Automation is mainly designed for general automation equipment. Its C7 precision grade (lead error ≤0.023mm/300mm) can meet the basic positioning accuracy requirements of sorting, assembly, handling and other scenarios. For high-precision automation scenarios such as precision processing and precision testing that require micron-level positioning accuracy, it is recommended to select C5 or higher precision ball screws.

Q: What is the service life of this product under long-term continuous operation?

A: Under normal operating conditions (proper lubrication and maintenance, no overload), the service life of the product can reach more than 55,000 hours. The specific service life will be affected by the operating frequency, load size and working environment of the equipment. Regular lubrication and maintenance can effectively extend the service life.

Q: How to select the appropriate lead specification for different automation equipment?

A: For equipment that needs high-speed movement (such as sorting equipment), it is recommended to select a large lead (60mm-70mm) to maximize movement efficiency; for equipment that needs to balance speed and stability (such as handling equipment), it is recommended to select a medium lead (40mm-50mm); when selecting, it is also necessary to match the motor speed and load capacity of the equipment to avoid overload operation.

Q: What is the difference between this product and C5 grade large lead ball screws for automation?

A: The core difference lies in precision and cost. C5 grade products have higher precision (lead error ≤0.015mm/300mm) and are suitable for high-precision automation scenarios; this product adopts C7 precision grade, which meets the basic positioning needs, and the cost is 30%-40% lower than C5 grade products, which is more suitable for general automation equipment pursuing cost-effectiveness.

Q: What maintenance measures are needed during the use of the product?

A: Regular maintenance mainly includes two aspects: first, regularly clean the surface of the ball screw to remove dust and debris, and check the integrity of the dust-proof seal; second, add high-quality lubricating grease every 6-12 months (depending on the operating frequency) to reduce friction between the ball and the raceway and extend the service life. For humid or dusty environments, the maintenance cycle should be shortened appropriately.
