This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ16X90-40B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ16X90-40B 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 ACPJ16X90-40B
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ16X90-40B is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø16mm bore and 90mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ16X90-40B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X90-40B
The ACPJ16X90-40B is a double acting compact cylinder with an adjustable extend stroke: a stop screw trims the 90 mm stroke by up to 40 mm, giving a usable range of 50-90 mm on site. At 0.5 MPa the 16 mm bore delivers 100.5 N push and 75.4 N pull, rising to 140.7 N push at 0.7 MPa, with a theoretical peak of 20.5 kgf at 1.0 MPa. The 90 mm stroke exceeds the 75 mm standard maximum for bore 16, so this unit is made to order. Note: this model is discontinued; the current-production replacement is the ACEJ16X90.
The hard-anodized aluminium body with an S45C hard-chrome rod follows the ISO 21287 short-body format, saving 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 cannot fit. A fixed TPU bumper sits at both ends and the rod carries a male thread (B code). For planning: treat about 60 N (0.6 of the 100.5 N push) as the realistic working force at 0.5 MPa, which lifts roughly 5 kg vertically with a 2:1 margin. Operating window is 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s. No magnet is fitted; the optional -S code adds one for CMSE / DMSE switches.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X90-40B (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 (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 101 N | 75 N |
| 0.7 MPa | 141 N | 106 N |
| Max (@1.0 MPa) | 21 kgf | |
The ACEJ16X90-40B 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 ACPJ16X90-40B Is Used
Fixture clamp with trimmable travel
On a small machining fixture, the stop screw lets a setter dial the clamp stroke anywhere between 50 and 90 mm, so one cylinder serves several part heights without re-plumbing. The 100.5 N push at 0.5 MPa suits light aluminum or plastic parts.
Ejector on an electronics assembly bench
Pushing finished PCB trays off a nest needs short, repeatable travel; the 60 N practical working force and 30-500 mm/s speed band keep cycle times tight inside a compact guard where a full-length body would not fit.
Small carton flap tucker
A packaging machine closing top flaps on cosmetic cartons uses the male rod thread with a knuckle to swing the flap home; the fixed TPU bumper quiets the end of travel at up to 500 mm/s.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X90-40B with the ACEJ16X90-40B
Size between bores: the 12 mm bore gives 56.5 N push at 0.5 MPa, while stepping up to 20 mm raises it to 157.1 N, so the 16 mm at 100.5 N sits mid-range for light clamping and part ejection. If your stroke must be trimmed in the field, the -40 window here allows 50-90 mm of extend travel; remember the stop screw is a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost. Mounting uses the FA/FB flange or LB foot on the ISO 21287 face, and the male rod thread (B) suits knuckle brackets. Since this model is discontinued, order the ACEJ16X90 as the drop-in successor and confirm the ISO 21287 mounting dimensions before swapping, as the ACP was DIN-standard.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X90-40B
- ✓ 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 ACPJ16X90-40B FAQ
At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa that rises to 140.7 N push and 105.6 N pull, with a theoretical maximum of 20.5 kgf at 1.0 MPa. For real work, plan on about 60 N (0.6 of the push figure), which corresponds to lifting roughly 5 kg vertically with a 2:1 margin. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the port is M5x0.8 on the 16 mm bore.
The -40 code is a 40 mm adjustment window: an external stop screw shortens the 90 mm extend stroke on site, so usable travel is 50-90 mm. It cannot lengthen the stroke beyond 90 mm, and it is a mechanical end stop only - it does not hold a load if air pressure is lost. This model is discontinued; the current-production drop-in is the ACEJ16X90 (same bore, stroke and force class). Confirm the ISO 21287 mounting dimensions before swapping, since the ACP was DIN-standard. Also note no magnet is fitted unless you order the optional -S code for CMSE / DMSE switches.
