FAQ

- Q: Is the C7 High Speed Large Lead Rolled Ball Screw for Robots suitable for high-precision robot scenarios?

A: The C7 High Speed Large Lead Rolled Ball Screw is mainly designed for general-purpose robots, with C7 precision grade (lead error ≤0.023mm/300mm), which can meet the basic positioning accuracy requirements of general-purpose robots such as handling and sorting. It is not suitable for high-precision robot scenarios such as welding robots and assembly robots that require micron-level positioning accuracy; for such high-precision scenarios, it is recommended to choose 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 robot. Regular lubrication and maintenance can effectively extend the service life.

- Q: How to choose the appropriate lead specification for different general-purpose robots?

A: For robots that need high-speed movement (such as sorting robots), it is recommended to choose a large lead (60mm-75mm) to maximize movement efficiency; for robots that need to balance speed and stability (such as handling robots), it is recommended to choose a medium lead (40mm-50mm); when selecting, it is also necessary to match the motor speed and load capacity of the robot to avoid overload operation.

- Q: What is the difference between this product and C5-level ball screws for robots?

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

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

A: Regular maintenance mainly includes two aspects: first, clean the surface of the ball screw regularly to remove dust and debris, and check the integrity of the dust-proof seal; second, add high-quality lithium-based 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.
