This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE32X20SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE32X20SB 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 ACP32X20SB
The AirTAC Airtac ACP Compact Cylinder ACP32X20SB is a double acting DIN-standard tight/compact air cylinder with a Ø32mm bore and 20mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE32X20SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP32X20SB
The ACP32X20SB is a double acting compact cylinder in the DIN-standard ACP series, with a 32 mm bore and a short 20 mm stroke. Air drives the piston both ways, so it pushes 402.1 N and pulls 345.6 N at 0.5 MPa, rising to 563 N on the extend stroke at 0.7 MPa. The hard-anodized aluminium body with an S45C hard-chrome rod keeps the mounting length roughly half that of an ISO 15552 profile cylinder, which is why this size fits so well inside tight jigs and guarding. A fixed TPU bumper sits at each end of the stroke.
This unit carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be fitted for end-of-stroke sensing, and the B code gives a male rod thread instead of the female version. For planning, treat about 240 N (roughly 24 kg of vertical lift with a 2:1 margin) as the usable working force at 0.5 MPa rather than the full 402.1 N rating. Note that ACP is discontinued: the current-production drop-in is the ISO 21287 ACE32X20 in the same bore, stroke and force class, so confirm ISO 21287 mounting dimensions before you swap.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE32X20SB (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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 kgf | |
The ACE32X20SB 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 ACP32X20SB Is Used
Fixture clamping on CNC pallets
The 20 mm stroke and 402.1 N extend force at 0.5 MPa suit short-travel clamps that lock workpieces on CNC pallet changers, with the male rod thread taking a knuckle directly.
Position-verified gate on a bottling line
Because the -S magnet is fitted, CMSE or DMSE switches confirm gate open and closed states on bottle diverters, inside a body about 50% shorter than an ISO 15552 profile cylinder.
Small press fit of bushings
Around 24 kg of usable vertical push at 0.5 MPa (with a 2:1 margin) handles light bushing or dowel pressing in electronics assembly, backed by the 82 kgf theoretical maximum at 1.0 MPa.
Replacing the Airtac ACP Compact Cylinder ACP32X20SB with the ACE32X20SB
At 32 mm bore this model sits in the mid force band: the 25 mm bore pushes 245.4 N at 0.5 MPa and the 40 mm bore reaches 628.3 N, so step up or down if your load sits near the 402.1 N extend figure. The 20 mm stroke is well inside the 200 mm maximum standard stroke for this bore. Remember the piston drifts when air is lost, so add a rod lock or pilot check valve if the load must stay put. FA/FB flange, LB foot and CA/CB clevis mountings bolt straight on, and the male rod thread suits I/Y knuckles. Order ACE32X20 as the current replacement and verify the ISO 21287 footprint.
Replacement checklist
- ✓ Current-production ACE → ACE32X20SB
- ✓ 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 ACP32X20SB FAQ
Push is 402.1 N and pull 345.6 N at 0.5 MPa; at 0.7 MPa push rises to 563 N and pull to 483.8 N, with a theoretical maximum of 82 kgf at 1.0 MPa. It is a double acting compact cylinder, 32 mm bore, 20 mm stroke, 12 mm rod with male thread, 1/8" port, running on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C, speed 30-500 mm/s, with a fixed TPU bumper at both ends.
AirTAC no longer produces the ACP family. The current-production successor is ACE32X20, an ISO 21287 compact cylinder in the same 32 mm bore, 20 mm stroke and force class. It is a drop-in in function, but because ACP was built to a DIN standard, confirm the ISO 21287 mounting dimensions before swapping. The ACE family also covers related variants such as single-acting ASP/ATP, double-rod ACPD and adjustable ACPJ types.
