This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ16X70-30SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ16X70-30SB 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 ACPJ16X70-30SB
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ16X70-30SB 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 ACEJ16X70-30SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X70-30SB
This is a double acting compact cylinder with an adjustable stroke, now discontinued: the current-production replacement is the ACEJ16X70, which keeps the same 16 mm bore, 70 mm stroke and force class. The -30 code gives a 30 mm adjustment window, so an external stop screw trims the extend stroke anywhere between 40 and 70 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. Because the short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, it slots into tight jigs and guarding where a full-length body will not fit.
For sizing, plan on about 60 N of real work at 0.5 MPa (roughly 0.6 of the rated push) rather than the full 100.5 N, which corresponds to lifting about 5 kg vertically with a 2:1 margin. The S code means the magnet is fitted, so CMSE or DMSE reed and solid-state switches can be mounted directly on the body; the B code gives a male rod thread. A fixed TPU bumper sits at both ends, and the hard-anodized aluminium body carries an S45C hard-chrome rod with M5x0.8 ports.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X70-30SB (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 ACEJ16X70-30SB 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 ACPJ16X70-30SB Is Used
Small-parts ejection on assembly fixtures
The 40-70 mm trimmed extend stroke and 100.5 N push at 0.5 MPa suit kicking finished bushings or clips off a jig table, with the male rod thread taking an I-type knuckle.
Position-verified clamping in test rigs
Because the -S magnet is fitted, CMSE or DMSE switches report rod position on the 70 mm stroke, useful for confirming a workpiece is seated before a leak or electrical test starts.
Compact press-fit of connectors
About 60 N of practical force at 0.5 MPa presses small terminals or dowels into plastic housings inside tight machine frames where a full-length ISO 15552 profile body would not fit.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X70-30SB with the ACEJ16X70-30SB
At 16 mm bore this unit sits between the 12 mm size (56.5 N push at 0.5 MPa) and the 20 mm size (157.1 N push at 0.5 MPa), so step up if your load needs more than about 60 N of usable force. The stop screw only shortens the extend stroke within the 30 mm window and does not lock the piston: on air loss the rod still drifts, so add a separate holding valve if the load must stay put. FA/FB flange and LB foot mountings bolt to the standard face, and the fitted -S magnet pairs with CMSE / DMSE switches. Before ordering, note this model is discontinued and confirm the ISO 21287 mounting dimensions of the ACEJ16X70 drop-in replacement.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X70-30SB
- ✓ 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 ACPJ16X70-30SB FAQ
At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa those figures rise to 140.7 N push and 105.6 N pull, with a theoretical maximum of 20.5 kgf at 1.0 MPa. The -30 code sets a 30 mm adjustment window: a stop screw shortens the 70 mm extend stroke by up to 30 mm, giving a usable range of 40-70 mm. The stop is a mechanical end stop only, not a mid-stroke lock, so the rod can still drift if air is lost.
No, the ACPJ family is discontinued. The current-production drop-in is the ACEJ16X70, which matches the same 16 mm bore, 70 mm stroke and force class in the ISO 21287 short-body format. Confirm the ISO 21287 mounting dimensions against your existing fixture before swapping, since the ACP was built to the DIN standard. Also note the magnet on this unit comes from the -S code; on a replacement order you must specify S again to keep CMSE / DMSE switch capability.
