Mechanical Specifications and Dimensions

The document provides detailed mechanical dimensions and specifications for a component, including various screw sizes such as 12× M3, 54× M4, 6× M5, and N× M5 with torque specifications (e.g., N*M5 8). The effective stroke (S) ranges from 100 mm to 3900 mm, with corresponding total lengths (L) calculated as L = S + 224 mm, ranging from 324 mm to 4124 mm. Mechanical limits are specified at 105 and 109 mm.

Fastening and Assembly Details

Fastening details include quantities and sizes of screws required for assembly, such as 12 M3 screws, 54 M4 screws, and 6 M5 screws. Torque values for M5 screws are indicated as 8 Nm. The document also includes a table correlating stroke lengths (S), total lengths (L), and the number of fasteners (N), which increases with stroke length.

Material and Surface Treatment

Material codes and surface treatments are referenced, though specific materials are not detailed in the excerpt. Surface roughness values are indicated with typical values such as 0.25G, 1.6, 2.0, and 8.0 micrometers. Heat treatment and surface treatment processes are mentioned but not elaborated.

Tolerances

Dimensional tolerances are specified based on size ranges, for example:

• ±0.1 mm for dimensions between 3 mm and 60.5 mm
• ±0.2 mm for 30 mm to 120 mm
• Up to ±2 mm for dimensions between 2000 mm and 4000 mm

Geometric tolerances are also provided, with values ranging from 0.02 mm to 0.4 mm depending on the dimension range.

Document Control and Revision

The document includes a revision table with columns for date revised, summary, and reviser. It is marked as a technical document belonging to 福誉科技 (Fuyu Technology) and restricts unauthorized copying without permission from the document control center.

Model and Scale

The model referenced is A0FBL60-F40-L V2, with a scale of 1:5. The document appears to be part of a standardization process dated August 12, 2025.

Summary

This technical document outlines mechanical dimensions, fastening requirements, tolerances, and surface treatment guidelines for a mechanical component with variable stroke lengths. It emphasizes precise dimensional control and assembly specifications to ensure proper function and standardization.
