This model is discontinued

AirTAC has phased out the MAL series. The drop-in replacement is ACE16X40SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE16X40SB in place of this model. The ACE replacement is a current-production ISO 21287 compact cylinder in the same bore, stroke and force class, with a matching short body and the same mounting-accessory family, so it fits the same envelope. Confirm mounting-interface dimensions against the ACE datasheet before ordering.

Airtac ACP Compact Cylinder ACP16X40SB

The AirTAC Airtac ACP Compact Cylinder ACP16X40SB is a double acting DIN-standard tight/compact air cylinder with a Ø16mm bore and 40mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE16X40SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP16X40SB

The ACP16X40SB is a double acting compact cylinder in the discontinued AirTAC ACP DIN-standard series, with a 16 mm bore and 40 mm stroke. At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa those rise to 140.7 N and 105.6 N, with a theoretical peak of 20.5 kgf at 1.0 MPa. The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures where a full-length body cannot. The S code means the optional -S magnet is fitted, so CMSE or DMSE reed and solid-state switches can be mounted directly on the hard-anodized aluminium body.

Practically, plan on about 60 N (roughly 6 kg of force) of usable work at 0.5 MPa instead of the full 100.5 N rating; halving the vertical-lift equivalent of about 10 kgf gives a 2:1 margin, so this cylinder comfortably lifts about 5 kg vertically. The B code gives a male rod thread on the 8 mm rod, the port is M5x0.8, and a fixed TPU bumper sits at each end. Note this model is discontinued: the current-production drop-in is ACE16X40, and buyers should confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE16X40SB (ISO 21287) carries the same bore/stroke/force class; confirm mounting-interface dimensions against the ACE datasheet before installation. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G.

Where the Airtac ACP Compact Cylinder ACP16X40SB Is Used

sensors

Position-flagged slide on a small assembly cell

The fitted -S magnet lets a CMSE or DMSE switch confirm end-of-stroke on a 40 mm slide, while the 100.5 N push at 0.5 MPa seats light connectors or clips.

precision_manufacturing

Compact jig clamping in electronics fixtures

With about 6 kg of usable clamping force at 0.5 MPa and a body roughly 50% shorter than an ISO 15552 profile cylinder, it clamps PCB trays inside crowded jig plates.

vertical_align_bottom

Light part ejection under a small press head

The 140.7 N push at 0.7 MPa ejects finished components weighing up to about 5 kg from a nest, with the male rod thread picking up an I/Y knuckle directly.

Replacing the Airtac ACP Compact Cylinder ACP16X40SB with the ACE16X40SB

At 16 mm bore you sit between the 12 mm size (56.5 N push at 0.5 MPa) and the 20 mm size (157.1 N push at 0.5 MPa); if your load needs more than about 60 N of real work, step up to the 20 mm bore. The 40 mm stroke is well inside the 75 mm maximum standard stroke for this bore, so it is a catalogue item, not a made-to-order length. The male rod thread (B) suits I/Y rod knuckles, and FA/FB flange, LB foot or CA/CB clevis mounts bolt to the same face. A plain cylinder drifts when air is lost, so add a rod lock or pilot check valve if the load must be held. Order ACE16X40 as the current replacement and verify the ISO 21287 mounting dimensions first.

Replacement checklist

  • ✓ Current-production ACE → ACE16X40SB
  • ✓ Same bore / stroke / force class
  • ✓ Confirm ISO 21287 mounting dimensions
  • ✓ Port/thread type (PT / G)
  • ✓ Add -S for magnet if you need sensors

Airtac ACP Compact Cylinder ACP16X40SB FAQ

Double acting on a 16 mm bore: push 100.5 N and pull 75.4 N at 0.5 MPa; push 140.7 N and pull 105.6 N at 0.7 MPa; theoretical maximum 20.5 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, rod 8 mm with male thread, port M5x0.8. The model is discontinued; ACE16X40 is the drop-in replacement.

The S in ACP16X40SB means the optional -S magnet is fitted, so CMSE reed or DMSE solid-state switches clamp onto the aluminium body for end-of-stroke signalling. Without the -S code there is no magnet in the piston. Also note the fixed TPU bumpers only decelerate at the ends - they do not hold the load, so use a rod lock or pilot check valve where a held position matters.
