This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ16X70-40SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ16X70-40SB 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 ACPJ16X70-40SB
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ16X70-40SB is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø16mm bore and 70mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ16X70-40SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X70-40SB
This ACPJ16X70-40SB is a double acting compact cylinder with an adjustable stroke: a stop screw trims the 70 mm extend stroke by up to 40 mm, giving a usable range of 30-70 mm on site. The 16 mm bore delivers 100.5 N push and 75.4 N pull at 0.5 MPa, rising to 140.7 N push at 0.7 MPa, with a theoretical peak of 20.5 kgf at 1.0 MPa. The male rod thread (B code) suits knuckle and tooling attachments, and the fitted -S magnet accepts CMSE / DMSE switches for end-of-stroke sensing.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding where a full-length body cannot. For sizing, plan on about 60 N of usable push at 0.5 MPa, which lifts roughly 5 kg vertically with a 2:1 margin. Note this model is discontinued: the current-production replacement is the ACEJ16X70, so confirm ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X70-40SB (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 ACEJ16X70-40SB 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 ACPJ16X70-40SB Is Used
Fixture clamping in CNC cells
The 30-70 mm adjustable range lets one cylinder clamp brackets of varying thickness on a machining fixture, with 100.5 N push at 0.5 MPa enough for light workholding.
Position-checked ejector on assembly stations
The fitted -S magnet pairs with CMSE / DMSE switches so a PLC confirms the rod has reached the trimmed extend position before the next cycle starts.
Carton push-off in compact packaging heads
With a body about 50% shorter than an ISO 15552 profile cylinder, the 70 mm stroke fits inside tight packaging frames to nudge cartons onto a takeaway conveyor.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X70-40SB with the ACEJ16X70-40SB
Choose this model when a 16 mm bore fits the job: 100.5 N push at 0.5 MPa covers light clamping and part-present checks. If you need more force, the 20 mm bore gives 157.1 N push at 0.5 MPa; if less, the 12 mm bore gives 56.5 N. The 40 mm adjustment window means one cylinder can serve several stroke points between 30 and 70 mm. FA/FB flange and LB foot mountings bolt to the standard face, and the fitted -S magnet works with CMSE / DMSE switches. Remember the stop screw sets the extend position but is not a mid-stroke lock: on air loss the piston still drifts. Order the ACEJ16X70 as the current drop-in successor.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X70-40SB
- ✓ 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 ACPJ16X70-40SB FAQ
At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa it pushes 140.7 N and pulls 105.6 N; the theoretical maximum is 20.5 kgf at 1.0 MPa. The -40 code gives a 40 mm adjustment window, so the 70 mm extend stroke can be trimmed anywhere down to 30 mm with the stop screw. Operating pressure is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and the M5x0.8 port follows the 16 mm bore.
It is a short ISO 21287-class compact cylinder with a hard-anodized aluminium body, an 8 mm S45C hard-chrome rod, male rod thread, and a fixed TPU bumper at each end that only decelerates at the ends. FA/FB flange and LB foot mountings bolt straight to the standard face. The ACPJ family is discontinued; the current-production drop-in is the ACEJ16X70 (same bore, stroke and force class) - confirm the ISO 21287 mounting dimensions before swapping.
