This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACE20X125SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACE20X125SB 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 ACP20X125SB
The AirTAC Airtac ACP Compact Cylinder ACP20X125SB is a double acting DIN-standard tight/compact air cylinder with a Ø20mm bore and 125mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE20X125SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP20X125SB
Double acting on both strokes, the ACP20X125SB is a DIN-standard compact cylinder with a 20 mm bore, a 125 mm made-to-order stroke and a male rod thread (B code). Push force is 157.1 N and pull 117.8 N at 0.5 MPa, rising to 219.9 N at 0.7 MPa, with a theoretical maximum of 32 kgf at 1.0 MPa. The hard-anodized aluminium body carries M5x0.8 ports, and the S45C piston rod is hard-chrome plated for long service.
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 and guarding. This model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be mounted for end-position sensing. For sizing, plan on about 94 N of usable push at 0.5 MPa, which lifts roughly 8 kg vertically with a 2:1 margin. Note the ACP family is discontinued; the current-production drop-in is ACE20X125.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE20X125SB (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 ACE20X125SB 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 ACP20X125SB Is Used
Compact jig clamping
The 157.1 N push at 0.5 MPa clamps small aluminium brackets in drilling jigs, and the short body fits where a full-length profile cylinder cannot.
Push-off on packaging lines
With about 8 kg of vertical-lift margin, this bore nudges cartons or trays off a conveyor lane at speeds from 30 to 500 mm/s.
Position-checked test stations
The fitted -S magnet accepts CMSE or DMSE switches, so a QC bench can confirm full retraction before the next cycle starts.
Replacing the Airtac ACP Compact Cylinder ACP20X125SB with the ACE20X125SB
At 20 mm bore this sits between the 16 mm (100.5 N push at 0.5 MPa) and the 25 mm (245.4 N push at 0.5 MPa), so step up if your load needs more than about 94 N of working force. The 125 mm stroke exceeds the 100 mm standard maximum for this bore, so it is built to order. Choose the male rod thread (B) when your tooling threads onto the rod; FA/FB flange, LB foot or CA/CB clevis mountings bolt to the same face. Remember the piston drifts when air is lost - add a rod lock or pilot check valve if the load must stay put. Order ACE20X125 as the current replacement and confirm ISO 21287 mounting dimensions before swapping.
Replacement checklist
- ✓ Current-production ACE → ACE20X125SB
- ✓ 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 ACP20X125SB FAQ
At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa that rises to 219.9 N push and 164.9 N pull. The theoretical maximum is 32 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with proof pressure of 1.5 MPa (215 psi), and speed runs 30-500 mm/s.
No - the standard maximum for a 20 mm bore is 100 mm, so 125 mm is a made-to-order stroke. The ACP family is discontinued; the current-production successor is ACE20X125, which matches the bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP was built to the DIN standard.
