Calculation
Example) MBKWB32-100Z (Basic, ø32 [32‑mm diameter], 100 mm stroke)
- Basic weight: 0.56 (Basic, ø32 [32-mm diameter])
- Additional weight: 0.16 / 50 stroke
0.56 + +0.16 × 100/50 = 0.88kg

Precautions
- *Models without air cushion will have a rubber bumper. Since the bumpers are attached to both sides of the piston, the overall length is longer than the cylinder with air cushion as follows: ø32 (32‑mm diameter), ø40 (40‑mm diameter): 6 mm; ø50 (50‑mm diameter), ø63 (63‑mm diameter): 8 mm; ø80 (80‑mm diameter), ø100 (100‑mm diameter): 10 mm.
- *Product pictures are of representational models.
- *See the SMC catalog for information other than that detailed above.
