SFK1002-3RL-139-195-C7: high-precision 10mm diameter bi-directional ball screw

 
The SFK1002-3RL-139-195-C7 is a bidirectional rolled ball screw manufactured by Hojama. Produced via precision rolling processes and graded at accuracy class C7, it delivers a repeat positioning accuracy of ±0.05 mm per 300 mm. Equipped with two compact flanged nuts, this ball screw enables synchronous, counter-directional movement of the two nuts along left-hand and right-hand thread paths when the screw shaft rotates, ensuring exceptional high-speed performance and heavy-load bearing capacity.
 
Key Features of the SFK Series Ball Screws
1. Compact Design: Fitted with two small-sized flanged ball nuts on the screw shaft, the SFK rolled ball screw is ideally suited for applications requiring small leads and operating within confined installation spaces.
 
2. Low-Noise Operation: Thanks to its optimized internal ball circulation structure and precision-machined ball retainment system, the SFK series minimizes frictional resistance during operation, resulting in ultra-low operational noise.
 
3. Superior Durability: Hojama ball screws are crafted from high-quality bearing steel or stainless steel and integrated with proprietary precision manufacturing techniques. This combination ensures outstanding wear resistance and positioning accuracy under heavy-load conditions, while also providing excellent corrosion resistance for specialized working environments, laying a stable and reliable material foundation for automated transmission systems.
 
As a leading manufacturer in the ball screw industry, Hojama offers an extensive range of ball screw models and specifications, along with comprehensive customization services to meet diverse customer requirements. Beyond ball screws, our linear transmission portfolio includes sliding screws, linear guides, ball splines, and linear modules.
