This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ16X40-30SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ16X40-30SB 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 ACPJ16X40-30SB
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ16X40-30SB is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø16mm bore and 40mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ16X40-30SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X40-30SB
The ACPJ16X40-30SB is a double acting compact cylinder with an adjustable extend stroke: the -30 stop screw trims the 40 mm stroke by up to 30 mm on site, giving a usable range of 10-40 mm. At 0.5 MPa it pushes 100.5 N and pulls 75.4 N, rising to 140.7 N at 0.7 MPa, with a theoretical peak of 20.5 kgf at 1.0 MPa. The male (B code) rod thread and M5x0.8 ports suit small clamping fixtures. Note: this ACPJ series is discontinued - the current drop-in is the ACEJ16X40.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jig plates and guarding where a full-length body cannot. Because the S code is ordered, the magnet is fitted, so CMSE or DMSE reed and solid-state switches mount directly on the hard-anodized aluminium body. Plan on about 60 N (roughly 6 kg of vertical lift) of practical work at 0.5 MPa rather than the full rating. Operating range is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, with a fixed TPU bumper at each end and an S45C hard-chrome rod.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X40-30SB (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 ACEJ16X40-30SB 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 ACPJ16X40-30SB Is Used
Small-parts press fitting
Seating dowel pins or bushings into aluminium housings on an electronics assembly bench, where the 100.5 N push at 0.5 MPa is enough and the 10-40 mm trim range lets one cylinder serve several part heights.
Position-verified gate on a test rig
Because the -S magnet is fitted, CMSE or DMSE switches confirm the clamped position on a leak-test fixture, with the stop screw set so the 40 mm stroke lands exactly on the seal face.
Compact ejection in a jig plate
Kicking finished brackets off a drilling jig where the short body fits under the drill head - about 50% shorter than an ISO 15552 profile cylinder, with the male rod thread driving a knuckle on the ejector pin.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X40-30SB with the ACEJ16X40-30SB
Size up or down by force: the 12 mm bore gives 56.5 N push at 0.5 MPa, while the 20 mm bore reaches 157.1 N - pick the 16 mm when 100.5 N at 0.5 MPa covers the job with margin. The 40 mm stroke sits inside the 75 mm maximum standard stroke for this bore, so no made-to-order build is needed. FA/FB flanges and LB feet bolt to the same mounting family, and the male rod thread takes I/Y knuckles directly. The stop screw shortens the extend stroke only - it is not a mid-stroke lock, so the rod can drift if air is lost. For new projects, order the ACEJ16X40 and confirm ISO 21287 mounting dimensions before the swap.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X40-30SB
- ✓ 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 ACPJ16X40-30SB FAQ
At 0.5 MPa: 100.5 N push and 75.4 N pull. At 0.7 MPa: 140.7 N push and 105.6 N pull. Theoretical maximum is 20.5 kgf at 1.0 MPa. As a rule of thumb, plan on about 60 N of usable push at 0.5 MPa - roughly 6 kg of vertical lift with a sensible margin. Operating pressure is 0.15-1.0 MPa (22-145 psi) and speed is 30-500 mm/s.
The -30 code is a 30 mm window: an external stop screw shortens the 40 mm extend stroke on site, so the working range is 10-40 mm. It cannot lengthen the stroke past 40 mm, and it is a mechanical end stop only - on air loss the piston still drifts. The ACPJ series is discontinued; the current-production replacement is the ACEJ16X40 in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.
