Calculation
Example: CA2WL40-100 (axial foot, ø40 [40-mm tube bore diameter], 100 mm stroke)
- Basic weight: 1.18 (axial foot, ø40 [40-mm tube bore diameter])
- Additional weight: 0.28 / 50 stroke
- Cylinder stroke: 100 stroke
1.18 + +0.28 × 100/50 = 1.74kg

Precautions
- *Minimum Stroke for Auto Switch Mounting: The minimum stroke for mounting varies with the auto switch type and cylinder mounting type. In particular, the center trunnion type requires careful attention. See the SMC catalog for details.
- *The images are representative models.
- *See the SMC catalog for information other than that detailed above.
