This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ16X25-10S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ16X25-10S 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 ACPJ16X25-10S
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ16X25-10S is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø16mm bore and 25mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ16X25-10S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X25-10S
Double acting and adjustable, the ACPJ16X25-10S is a discontinued DIN-standard compact cylinder with a 16 mm bore, 25 mm stroke and a 10 mm trim window, so the extend stroke can be set anywhere between 15 and 25 mm with the external stop screw. Air at 0.5 MPa delivers 100.5 N on the push stroke and 75.4 N on the pull stroke, rising to 140.7 N push at 0.7 MPa. The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which makes it a fit for tight jigs and guarding where a full-length body cannot go.
Because the -S code is on this model, the magnet is fitted and CMSE or DMSE reed and solid-state switches can be mounted directly for end-of-stroke sensing. A practical sizing rule: at 0.5 MPa the 100.5 N push supports about 60 N of real work, which lifts roughly 6 kg vertically - halve that to about 3 kg if you want a 2:1 margin on a vertical lift. Note this model is discontinued; the current-production drop-in is the ACEJ16X25, so confirm ISO 21287 mounting dimensions before swapping, since the ACP body is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X25-10S (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 ACEJ16X25-10S 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 ACPJ16X25-10S Is Used
Fixture clamping on compact CNC jigs
The 100.5 N push at 0.5 MPa clamps small aluminium brackets during drilling, and the 15-25 mm trim range lets one cylinder serve fixtures of slightly different part heights.
Position-confirmed eject on an electronics assembly bench
With the fitted magnet and a DMSE solid-state switch, the controller confirms the rod has reached the trimmed stop before the pick-and-place head moves on.
Carton hold-down on a small case sealer
The short body fits under the low sealing head where an ISO 15552 profile cylinder would not, pressing flaps for about 3 kg vertical load with a 2:1 margin.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X25-10S with the ACEJ16X25-10S
At 16 mm bore this sits mid-range in the small ACPJ family: the 12 mm bore gives 56.5 N push at 0.5 MPa, while the 20 mm bore reaches 157.1 N - step up if your part weight exceeds the roughly 6 kg vertical-lift equivalent of this bore. The stop screw only trims the extend stroke within the 10 mm window and is not a mid-stroke lock; on air loss the piston still drifts, so add a separate holding valve if the load must stay put. FA/FB flange and LB foot mountings plus I/Y rod knuckles bolt to the standard face, and the female M4x0.7 rod thread takes standard accessories. Order the ACEJ16X25 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X25-10S
- ✓ 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 ACPJ16X25-10S FAQ
At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa push is 140.7 N and pull 105.6 N; theoretical maximum is 20.5 kgf at 1.0 MPa. It is double acting with a 10 mm adjustable window on a 25 mm stroke, runs on 0.15-1.0 MPa (22-145 psi) filtered air at 30-500 mm/s, has an M5x0.8 port, an 8 mm rod with female M4x0.7 thread, and a fixed TPU bumper at both ends.
Order the ACEJ16X25, the current-production ISO 21287 replacement: swap the P for an E and you get the same bore, stroke and force class with a matching short body and mounting family. Because the ACP body is DIN-standard rather than ISO 21287, confirm the mounting dimensions against the ACEJ drawing before committing the swap.
