This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X150-100S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X150-100S 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 ACPJ Adjustable Compact Cylinder ACPJ20X150-100S
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X150-100S is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø20mm bore and 150mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ20X150-100S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X150-100S
The ACPJ20X150-100S is a double acting compact cylinder with an adjustable stroke: a stop screw trims the extend stroke anywhere within the ordered 100 mm window, so the working range runs from 50 to 150 mm. At 0.5 MPa it pushes 157.1 N and pulls 117.8 N, rising to 219.9 N on the extend side at 0.7 MPa. The 150 mm stroke exceeds the 100 mm standard maximum for a 20 mm bore, so this unit is made to order. Note that the ACPJ family is discontinued; the current-production drop-in is the ACEJ20X150, and buyers should confirm ISO 21287 mounting dimensions before swapping.
The short ISO 21287 body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight jigs and guarding where a full-length body will not fit. The hard-anodized aluminium body carries an S45C hard-chrome rod, fixed TPU bumpers at both ends, and the -S magnet this model carries lets CMSE or DMSE switches report position. As a rule of thumb, plan on about 94 N (roughly 9.6 kg) of usable push at 0.5 MPa, so it lifts about 4.8 kg vertically with a 2:1 margin. Speed range is 30-500 mm/s over 0.15-1.0 MPa (22-145 psi).

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X150-100S (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 ACEJ20X150-100S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X150-100S Is Used
Ejection on a small press jig
The 50-150 mm adjustable window lets one cylinder serve several die heights on a compact stamping fixture, with 157.1 N of push at 0.5 MPa clearing light parts.
Position-verified clamp on an assembly cell
With the fitted -S magnet, CMSE or DMSE switches confirm the clamp is retracted before a robot picks the part, inside a guard too short for a full-length body.
Light part lowering on a packaging line
The stop screw sets a repeatable short extend stroke for placing cartons up to about 4.8 kg vertically, with TPU bumpers softening both ends at 30-500 mm/s.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X150-100S with the ACEJ20X150-100S
Size this bore by force: at 0.5 MPa the 20 mm bore gives 157.1 N push, while the 16 mm bore gives 100.5 N and the next class up starts at 32 mm bore. Keep the external stop as a stroke trim only - on air loss the piston still drifts, so it is not a load-holding brake. FA/FB flange and LB foot mountings plus I/Y rod knuckles bolt to the ISO 21287 face. Since this model is discontinued, order the ACEJ20X150 as the current replacement and verify mounting dimensions against your fixture.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X150-100S
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ACPJ Adjustable Compact Cylinder ACPJ20X150-100S FAQ
At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa it pushes 219.9 N and pulls 164.9 N. Theoretical maximum is 32 kgf at 1.0 MPa. The 20 mm bore has a 10 mm rod, an M5x0.8 port and an M6x1.0 female rod thread, and the 150 mm stroke is a made-to-order length above the 100 mm standard maximum for this bore.
The -100 code is a 100 mm window: an external stop screw shortens the extend stroke on site, giving a usable 50-150 mm range. It is a mechanical end stop, not a mid-stroke lock. The ACPJ family is discontinued; the ACEJ20X150 is the current ISO 21287 drop-in in the same bore, stroke and force class - confirm mounting dimensions before swapping.
