SD series are economical Ball Screws which moves bi-directionally with a shaft, and perform centering, precise positioning. There are Precision Ball Screws C3, C5 grade.
Accuracy grades of SD series (Standardized Bidirectional Precision Ball Screws) are 2 kinds, JIS C3 and JIS C5. Axial play are 0 (Preload : C3) and 0.005mm or less(C5) corresponding to accuracy grades in stock.
Shafts and Nuts of SD series(Standardized Bidirectional Precision Ball Screws) adopts SCM415 (carburizing and quenching), surface hardness of Ball Screw part is HRC58-62.
SD series(Standardized Bi-directional Precision Ball Screws) are applied with anti-rust oil for rust prevention when unfinished end journal. Since anti-rust oil is not lubricant, apply Grease or lubrication oil before using Ball Screws. If there is no specific instruction, ABSSAC would recommend our original Grease (MSG No.2) as standard lubricant. Please feel free to contact us.
End-journal configuration of SD series (Standardized Bi-directional Precision Ball Screws) is not standardized. Please ask ABSSAC regarding additional machining with a drawing which shows end-journal profile.
Model number notation of SD series (Standardized Bi-directional Precision Ball Screws) is as follows.
