Precision Ground Ball Screws
Precision Ground Ball Screws (SG Series) are the choice when high linear accuracy (i.e., grades C3 or C5) and smooth movement is required.
A precision grinding process is used to create the ball screw thread. The drive side journal is machined ready for support bearing installation. The finished screw is matched with a high quality ball nut to create the final assembly.
These products are very highly efficient (about 90%) in translating rotary to linear motion.
