Precision Rolled Ball Screws

Precision Rolled Ball Screws (SR Series) are the choice where high efficiency and lower cost are important. A rolling process is used to create the ball screw thread. The rolled screw is matched with a high quality ball nut to create the final assembly.

These products are with screw accuracy grades ranging from C7 TO C10 are the most economical ball screw products.

Cost-Effectiveness: The rolling process is generally faster and less resource-intensive than grinding, making rolled ball screws significantly more economical to produce. This makes them accessible for a broader range of applications.
Good Lead Accuracy: While not as precise as ground ball screws, modern rolling techniques can achieve very respectable lead accuracies, often sufficient for a wide variety of industrial and commercial applications.
Work Hardening Benefits: The cold-forming process of rolling actually work-hardens the surface of the screw threads. This increases their hardness and strength, contributing to improved wear resistance and overall durability.
Smooth Surface Finish: The rolling process can produce a smooth surface finish on the threads, contributing to efficient operation and reduced friction.
Faster Production: The nature of the rolling process allows for higher volume production, making rolled ball screws more readily available for large-scale manufacturing needs.
