This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ20X150-10SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ20X150-10SB 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 ACPJ20X150-10SB
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ20X150-10SB 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 ACEJ20X150-10SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X150-10SB
The ACPJ20X150-10SB is a double acting compact cylinder with an adjustable extend stroke: a stop screw trims the 150 mm stroke by up to 10 mm, giving a usable range of 140-150 mm. The 20 mm bore delivers 157.1 N push and 117.8 N pull at 0.5 MPa, rising to 219.9 N push at 0.7 MPa. The 150 mm stroke exceeds the 100 mm maximum standard stroke for this bore, so it is a made-to-order item. This model is discontinued; the current-production replacement is the ACEJ20X150, which matches the same bore, stroke and force class.
Its short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight gantries and guarding where a full-length body will not reach. The male rod thread (B code) suits external knuckles and tooling plates, and the fitted -S magnet lets you add CMSE or DMSE switches for end-of-stroke sensing. At 0.5 MPa the push force lifts about 16 kg vertically; halve that for a 2:1 margin and plan on roughly 8 kg of real lift. Fixed TPU bumpers at both ends absorb the rod at each limit, and speed spans 30-500 mm/s across 0.15-1.0 MPa (22-145 psi) of clean, 40 um filtered air.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X150-10SB (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 ACEJ20X150-10SB 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 ACPJ20X150-10SB Is Used
Small-parts press fitting
The 219.9 N push at 0.7 MPa seats bearings or dowel pins into aluminium housings on an electronics assembly cell, with the 10 mm trim dialing the stroke to the fixture depth.
Gantry pick-and-place indexing
A 150 mm reach moves PCB trays between conveyor lanes, and the fitted -S magnet drives CMSE switches to confirm extend and retract on the PLC.
Packaging machine gate drop
The rod swings a divert gate down at the end of a carton line; about 8 kg of practical vertical lift at 0.5 MPa with a 2:1 margin covers lightweight gate tooling.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X150-10SB with the ACEJ20X150-10SB
Size the load against 157.1 N push at 0.5 MPa; if your jig needs more, step up to a 25 mm or 32 mm bore, and if the force is generous, a 16 mm bore (100.5 N push at 0.5 MPa) saves space. The 10 mm adjustment window only shortens the extend stroke - it is a mechanical end stop, not a mid-stroke lock, so the rod can still drift if air is lost. Match FA/FB flange or LB foot mounts to the ISO 21287 face, and remember the -S magnet is what enables CMSE / DMSE switch mounting. For new builds, order the ACEJ20X150 instead and confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X150-10SB
- ✓ 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 ACPJ20X150-10SB FAQ
Push is 157.1 N and pull 117.8 N at 0.5 MPa; at 0.7 MPa push rises to 219.9 N and pull to 164.9 N, with a theoretical maximum of 32 kgf at 1.0 MPa. It is double acting with a 10 mm adjustment window on the 150 mm stroke, runs 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, M5x0.8 ports and a 10 mm male-thread rod. The 150 mm stroke is non-standard for this bore and made to order.
An external stop screw shortens the extend stroke by up to 10 mm, so the effective range is 140-150 mm; it cannot lengthen the stroke past 150 mm, and it is an end stop only - it never brakes or holds a load if air is lost. The ACPJ family is discontinued; the current drop-in is the ACEJ20X150 (same bore, stroke and force class). Confirm the ISO 21287 mounting dimensions before swapping, because the ACP is DIN-standard.
