Mechanical Limits and Stroke Specifications

The document specifies mechanical limit positions and effective stroke lengths for an electric cylinder actuator. The mechanical limit positions are indicated at 50 mm and 20 mm with additional dimensions such as 35 mm, 58 mm, and safety distances of 5 ± 1 mm. The effective stroke is defined as S, with additional parameters such as S+177 and S+107 indicating extended stroke ranges including safety margins.

Dimensions and Installation Details

Key dimensions include a rod movement range of 2.5 mm and a total length L calculated as L = S + 285 mm. The actuator includes an oil injection hole and mechanical limit positions are clearly marked. The motor installation method is specified as BL (Motor Left Side), and the electric cylinder installation is L1 (Base installation type).

Motor and Accessories

The motor referenced is a Fuyu servo motor rated at 750W with a 5x reducer, noted as a reference example with actual dimensions to be confirmed. Front-end connection accessories include joint bearings (SY type), internal thread (B), and external thread (A).

Stroke Lengths and Corresponding Dimensions

Optional motors include the Fuyu 750W servo motor weighing 2.05 kg and the 750W servo motor with reducer weighing 5 kg.

Tolerances and Surface Treatments

Dimensional tolerances are specified based on size ranges, for example ±0.1 mm for dimensions between 3-60.5 mm, increasing up to ±2 mm for dimensions between 2000-4000 mm. Geometric tolerances are also defined, with values such as 0.02 mm for ranges >10-30 mm and up to 0.4 mm for larger ranges. Surface roughness and heat treatment notes are included but not detailed in this excerpt.
