Calculation (Example) MBKB32-100Z (basic type, ø32 mm, 100 st)

  • Basic weight: 0.47 kg (Basic type, ø32 mm)
  • Additional weight: 0.12 kg / 50 stroke
  • Cylinder stroke: 100 stroke

0.47 + 0.12 × 100/50 = 0.71 kg

  • *Seal kit includes 4, 5, 6 and 8. Order the seal kit using the kit number corresponding to each tube inner diameter.
  • *The seal kit includes a grease pack. (ø32 to 50 mm: 10 g, ø63 mm and ø80 mm: 20 g, ø100 mm: 30 g).
  • *Contact SMC if it is necessary to order a grease pack separately.
  • *Models without air cushion will have a rubber bumper. As bumpers are attached to both sides of the piston, the overall length is increased as follows: ø32 mm and ø40 mm: 6 mm, ø50 mm and ø63 mm: 8 mm, ø80 mm and ø100 mm: 10 mm.
