What do we need to know about the MB Series air and rubber cushions?

When the piston collides with the cover and stops at the cylinder stroke end, if the speed and load weight applied to the piston rod are high, impact (vibration and noise) will occur. If this impact is repeated, it will affect the durability of the cylinder and the machine. To absorb the impact generated at the stroke end, the following two cushion mechanisms are available, according to the purpose. ・ Rubber cushion: Urethane rubber is used to mitigate the impact noise. (Low cushioning effect) ・ Air cushion: Raises the back pressure just before the stroke end, absorbing impact. (Cushioning effect)

Is it possible to use the MB series with an auto switch attached to the MB cylinder without a magnet later?

Only the MDB type with a magnet built into the piston part can be used with an autoswitch (magnetic proximity switch). Note) Magnets alone are not shipped as parts.

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.
