FAQ

Rolled ball screws are manufactured through a thread-rolling process, providing a more cost-effective solution for a wide range of industrial automation and material-handling applications. Most rolled ball screws available on the market are typically offered in accuracy grades ranging from C7 to C10, while GTEN rolled ball screws can achieve C5 accuracy.
Ground ball screws are manufactured by precision grinding the ball raceway grooves, enabling higher lead accuracy and positioning performance. They are commonly used in machine tools, semiconductor equipment, and high-precision positioning systems, although they generally involve a higher manufacturing cost.
