This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X150-100 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X150-100 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 ACPJ20X150-100
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X150-100 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 ACEJ20X150-100 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X150-100
This double acting ACPJ20X150-100 gives a 20 mm bore and a 150 mm stroke with a 100 mm adjustment window, so an external stop screw trims the extend stroke anywhere in a 50-150 mm range on site. At 0.5 MPa it pushes 157.1 N and pulls 117.8 N, and the short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder - useful in tight gantries and guarding. Note that the 150 mm stroke exceeds the 100 mm maximum standard stroke for this bore, so it is a made-to-order item.
The hard-anodized aluminium body carries an S45C hard-chrome rod, M5x0.8 ports and a fixed TPU bumper at each end, running at 30-500 mm/s on 0.15-1.0 MPa (22-145 psi) filtered air. As a planning figure, treat about 94 N (roughly 9.5 kg lifted vertically with a 2:1 margin) as the practical output at 0.5 MPa. This model is discontinued: the current-production drop-in is the ACEJ20X150, so confirm ISO 21287 mounting dimensions before swapping. No magnet is fitted on this version; the optional -S code adds one for CMSE / DMSE switches.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X150-100 (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 ACEJ20X150-100 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 ACPJ20X150-100 Is Used
Jig clamping on CNC fixtures
The 50-150 mm trimmed extend range lets one cylinder serve several fixture heights, with 157.1 N push at 0.5 MPa holding aluminium workpieces during drilling.
Small-part ejection from packaging lines
A 150 mm stroke ejects cartons or blisters off a conveyor, and the short body fits where an ISO 15552 profile cylinder would be about twice as long.
Vertical lift in a test station
With about 9.5 kg of practical vertical lift at 0.5 MPa (2:1 margin on the 157.1 N push), it raises sensor heads or small assemblies in automated test rigs.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X150-100 with the ACEJ20X150-100
Size against neighbours: the 16 mm bore delivers 100.5 N push at 0.5 MPa, while stepping up to a larger bore raises force further - pick 20 mm when 157.1 N push / 117.8 N pull at 0.5 MPa matches the job. The stop screw only shortens the extend stroke within the 100 mm window and is a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost. FA/FB flanges and LB feet bolt to the ISO 21287 face. Order the -S variant if you need the optional magnet for CMSE / DMSE switches. Replacement: ACEJ20X150.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X150-100
- ✓ 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 ACPJ20X150-100 FAQ
At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa push rises to 219.9 N and pull to 164.9 N. The theoretical maximum is 32 kgf at 1.0 MPa. The rod is 10 mm with an M6x1.0 female thread, ports are M5x0.8, and the extend stroke is trimmed by a stop screw within the 100 mm window (usable 50-150 mm).
The ACPJ family is discontinued; the current drop-in is the ACEJ20X150 in the same bore, stroke and force class - confirm ISO 21287 mounting dimensions before swapping. On this unit the -100 code sets a 100 mm adjustment window: a mechanical stop screw shortens the 150 mm extend stroke down to 50 mm. It is an end stop only, not a load-holding lock, and the 150 mm stroke is a made-to-order length because the bore's standard maximum is 100 mm.
