This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE20X75B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE20X75B 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 ACP20X75B
The AirTAC Airtac ACP Compact Cylinder ACP20X75B is a double acting DIN-standard tight/compact air cylinder with a Ø20mm bore and 75mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE20X75B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP20X75B
A double acting DIN-standard compact cylinder, the ACP20X75B drives a 20 mm bore through a 75 mm stroke with a 10 mm male-threaded rod (the B code). At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa those figures rise to 219.9 N and 164.9 N, with a theoretical ceiling of 32 kgf at 1.0 MPa. In practice, budget roughly 94 N of usable push at 0.5 MPa, which corresponds to lifting about 8 kg vertically with a 2:1 margin - enough to match against a real part weight before you commit. The 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.
This model is discontinued and is no longer in production; the current drop-in is ACE20X75, which matches the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP was built to a DIN standard. Construction is a hard-anodized aluminium body with an S45C hard-chrome rod, fixed TPU bumpers at both ends, and an M5x08 air port. Note the port is M5x0.8. Speed range is 30-500 mm/s over 0.15-1.0 MPa (22-145 psi), with a 1.5 MPa (215 psi) proof pressure. There is no magnet fitted on this code; order the -S variant if you need CMSE or DMSE switch sensing. A plain unit also drifts when air is lost - add a rod lock or pilot check valve if the load must stay put.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE20X75B (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 (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 118 N |
| 0.7 MPa | 220 N | 165 N |
| Max (@1.0 MPa) | 32 kgf | |
The ACE20X75B 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 ACP20X75B Is Used
Bench-top press jig
With about 94 N of practical push at 0.5 MPa, this bore suits light press-fitting of bushings and dowels in small electronics or watch-assembly jigs.
Pick-down ejector on a 3D printer gantry
The 75 mm stroke ejects finished prints or drops small trays, lifting roughly 8 kg vertically with a 2:1 margin at 0.5 MPa.
Compact fixture clamp in CNC automation
The short body saves about 50% of the length of an ISO 15552 profile cylinder, letting the clamp sit inside crowded milling-fixture plates where a full-length unit will not fit.
Replacing the Airtac ACP Compact Cylinder ACP20X75B with the ACE20X75B
Size against neighbours: the 16 mm bore gives 100.5 N push at 0.5 MPa, while stepping up to 25 mm raises it to 245.4 N - so the 20 mm sits mid-range for light clamping and indexing. The 75 mm stroke is within the 100 mm maximum standard stroke for this bore, so no made-to-order build is needed. Mount with FA/FB flange, LB foot or CA/CB clevis brackets on the standard face, and add the -S code only if CMSE/DMSE position switches are required. For new projects, specify ACE20X75 instead - it is the current-production successor in the same force class.
Replacement checklist
- ✓ Current-production ACE → ACE20X75B
- ✓ 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 ACP20X75B FAQ
It is a double acting unit: 157.1 N push and 117.8 N pull at 0.5 MPa, 219.9 N push and 164.9 N pull at 0.7 MPa, with a theoretical maximum of 32 kgf at 1.0 MPa. The model is discontinued; the current-production replacement is ACE20X75, same bore, stroke and force class - confirm ISO 21287 mounting dimensions before swapping.
It uses a hard-anodized aluminium body with an S45C hard-chrome rod, fixed TPU bumpers at both ends, an M5x0.8 port and a male-threaded 10 mm rod. The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder. Position sensing needs the optional -S magnet code, which enables CMSE or DMSE switches; without -S there is no magnet. Operating range is 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s.
