2 Deflector method ball screws Features Nut dimensions for more compactness Provided with an improved ball circulation system called deflector type system, which enables the nut dimensions to be as small as possible. (Example) Comparison of nut body s between ball screws with different methods (when the screws have a _12 mm, 3 mm lead, and 2. mm ball ) ube type: R123D Outside of the body = ø26 mm Deflector type: DR123J Outside of the body = ø21 mm Delivers excellent rotation balance achieved by distributing ball recirculation components evenly along the circumference of the nut body. Nut dimensions for more compactness ball screws provided with 1 to 1 mm lead are suitable for machines and equipment which require small-pitch feeding and precise positioning. ummary of the specifications haft : ø6 to ø5 mm, lead: 1 to 1 mm (Refer to the list of s and lead combinations for more details.) Accuracy grade: C to C7 grades (C to C5 grades for ball screws with integral nut) Nut type: single nut, integral nut Recirculation system: deflector method Deflector Appearance Ball Nut eries product line-up eries name Nut type Accuracy grade haft line-up haft type Product line DP series ingle nut C3 ø6 ~ ø14 One end finished tandard (in-stock) product line ingle nut C ~ C7 ø6 ~ ø5 DR series Integral nut C ~ C5 ø16 ~ ø5 Free design Custom product line In the standard (in-stock) product line, only the end on the fixed side is finished. he other end on the supported side needs additional end machining to fulfill your needs and operating conditions. Refer to page E-1 and after in this catalog for the -end process drawings for standard (in-stock) products. For the custom ball screws, custom design to fulfill your needs and operating conditions is required. B2
