This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE16X20B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE16X20B 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 ACP16X20B
The AirTAC Airtac ACP Compact Cylinder ACP16X20B is a double acting DIN-standard tight/compact air cylinder with a Ø16mm bore and 20mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE16X20B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP16X20B
The ACP16X20B is a double acting compact cylinder with a 16 mm bore and 20 mm stroke, built to the DIN-standard short-body format with a hard-anodized aluminium body and an S45C hard-chrome piston rod. The B code gives a male rod thread, and the port is M5x0.8. 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. Its short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures and guarding where a full-length body will not fit.
A fixed TPU bumper sits at both ends to soften end-of-travel contact; it is not adjustable and it never locks or holds a load, so for a suspended part add a rod lock or pilot check valve. The magnet is not fitted on this code: order the -S version (ACP16X20BS) if you want CMSE or DMSE switches. Note this model is discontinued - the current-production drop-in is ACE16X20, matching the same bore, stroke and force class, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE16X20B (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.
Theoretical Output Force (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 101 N | 75 N |
| 0.7 MPa | 141 N | 106 N |
| Max (@1.0 MPa) | 21 kgf | |
The ACE16X20B produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac ACP Compact Cylinder ACP16X20B Is Used
Small-part ejection from plastic molds
The 100.5 N push at 0.5 MPa is enough to kick finished caps or bushings out of shallow mold pockets, and the 20 mm stroke keeps the die block short.
Presence checking on electronics assembly lines
Order the -S magnet code and add CMSE or DMSE switches to confirm a PCB or connector seated within the 20 mm travel.
Light hold-down of aluminum extrusions before sawing
About 60 N of usable clamping force at 0.5 MPa secures thin bar stock against a stop, and the compact body fits between the fence and blade guard.
Replacing the Airtac ACP Compact Cylinder ACP16X20B with the ACE16X20B
At 100.5 N push and 75.4 N pull at 0.5 MPa, this 16 mm bore suits light clamping and small part transfer. Step down to a 12 mm bore (56.5 N push) for lighter loads, or up to 20 mm (157.1 N push) if your part weight grows. As a rule of thumb, plan on roughly 60 N of usable work at 0.5 MPa, which lifts about 5 kg vertically with a 2:1 margin. Mounting options include FA/FB flange, LB foot and CA/CB clevis, all bolting to the ISO 21287 face. Since ACP16X20B is discontinued, spec ACE16X20 for new builds and verify the ISO 21287 hole pattern first.
Replacement checklist
- ✓ Current-production ACE → ACE16X20B
- ✓ 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 ACP16X20B FAQ
At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa, 140.7 N push and 105.6 N pull. Theoretical maximum is 20.5 kgf at 1.0 MPa. It is double acting, runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, with a fixed TPU bumper at both ends.
The current-production replacement is ACE16X20 - swap the P for an E - which matches the same 16 mm bore, 20 mm stroke and force class in the ISO 21287 short-body format; confirm the mounting dimensions before swapping since the ACP was DIN-standard. For switching, the magnet is the optional -S code (ACP16X20BS); without it no CMSE or DMSE sensor can be mounted.
