The maximum dimension L1 is, as a rule, twice the thread size. (Example) For M3: L1 = 6 . Applicable shaft type: Y Machine female threads into the short shaft. . The maximum dimension L2 is, as a rule, twice the thread size. (Example) For M4: L2 = 8 . Applicable shaft type: Y Machine female threads into the long shaft. . The maximum dimension L1 is, as a rule, twice the thread size. (Example) For M3: L1 = 6 . Applicable shaft types: J, K, T Machine female threads into the short shaft. . The maximum dimension L2 is, as a rule, twice the thread size. (Example) For M4: L2 = 8 . Applicable shaft types: J, Z The long shaft can be further shortened by machining it into a stepped round shaft. (If shortening the shaft is not required, indicate “.” for dimension X.) (If not specifying dimension C1, indicate “.” instead.) . Applicable shaft types: J, K, T . Equal dimensions are indicated by the same marker. The short shaft can be further shortened by machining it into a stepped round shaft. (If shortening the shaft is not required, indicate “.” for dimension Y.) (If not specifying dimension C2, indicate “.” instead.) . Applicable shaft type: K . Equal dimensions are indicated by the same marker. Machine female threads into the short shaft. . The maximum dimension L2 is, as a rule, twice the thread size. (Example) For M5: L2 = 10 . Applicable shaft types: K, T, X Machine female threads into the long shaft. . The maximum dimension L1 is, as a rule, twice the thread size. (Example) For M3: L1 = 6 . Applicable shaft types: X, Z Additional Reminders 1. Enter the dimensions within a range that allows for additional machining. 2. SMC will make appropriate arrangements if no dimensional, tolerance, or finish instructions are given in the diagram. 3. The length of the unthreaded portion is 2 to 3 pitches. 4. Unless specified otherwise, the thread pitch is based on coarse metric threads. M3 x 0.5, M4 x 0.7, M5 x 0.8 M6 x 1 5. Enter the desired figures in the portion of the diagram. 6. XA31 to XA59 are the standard products that have been additionally machined. 7. Chamfer face of the parts machining additionally is C0.5.
