This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ16X60-50S, the same code under the new prefix. 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 ACPJ16X60-50S
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ16X60-50S is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø16mm bore and 60mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ16X60-50S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X60-50S
The ACPJ16X60-50S is a double acting, adjustable-stroke compact cylinder in the discontinued AirTAC ACPJ series. Its 16 mm bore delivers 100.5 N push and 75.4 N pull at 0.5 MPa, rising to 140.7 N at 0.7 MPa, with a theoretical peak of 20.5 kgf at 1.0 MPa. The -50 code gives a 50 mm adjustment window: an external stop screw trims the 60 mm extend stroke down to as little as 10 mm on site, so one cylinder covers a 10-60 mm working range. The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight jigs and guarding where a full-length body cannot.
This S-coded unit carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be clamped straight onto the hard-anodized aluminium body to report end positions. The S45C hard-chrome rod ends in a female M4x0.7 thread, air ports are M5x0.8, and fixed TPU bumpers sit at both ends. In practice, plan on about 60 N of usable push at 0.5 MPa, enough to lift roughly 3 kg vertically with a 2:1 margin. Note that ACPJ is discontinued: the current-production drop-in is ACEJ16X60, and buyers should confirm ISO 21287 mounting dimensions before swapping, since the ACP series is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X60-50S (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 | Force (both ways) |
|---|---|
| 0.5 MPa | 75 N |
| 0.7 MPa | 106 N |
| Max (@1.0 MPa) | 15 kgf |
ACPJ is double-rod: the rear rod that carries the stroke adjuster exits the rear cover, so both piston faces lose rod area. The rod-side (annular) area is used for both directions (conservative).

Where the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X60-50S Is Used
Small-parts ejection on assembly fixtures
The trimmed 10-60 mm extend range and 100.5 N push at 0.5 MPa suit knocking finished bushings or pins out of a light machining jig without overtravel.
Position-checked test stations
With the fitted -S magnet, CMSE or DMSE switches confirm rod position on a 60 mm maximum stroke, ideal for electronics test rigs cycling at 30-500 mm/s.
Compact clamping in tight guarding
A body about 50% shorter than an ISO 15552 profile cylinder lets the 16 mm bore clamp small brackets or PCB fixtures inside shallow machine frames.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X60-50S with the ACEJ16X60-50S
Size the job both ways: if 100.5 N push at 0.5 MPa is more than needed, the 12 mm bore gives 56.5 N in the same series; if the load needs more, step up to the 20 mm bore at 157.1 N. Keep in mind the stop screw only shortens the extend stroke and is not a mid-stroke lock - on air loss the piston still drifts, so do not rely on it to hold a load. FA/FB flange and LB foot mountings bolt to the standard face, and the fitted -S magnet accepts CMSE / DMSE switches. For new projects, order the ACEJ16X60, the current ISO 21287 replacement for this discontinued model.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X60-50S
- ✓ 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 ACPJ16X60-50S 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. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, and the air port is M5x0.8. The -50 stop screw trims the 60 mm extend stroke anywhere down to 10 mm.
An external stop screw shortens the extend stroke within the ordered 50 mm window, giving a usable 10-60 mm range; it cannot lengthen the stroke past 60 mm and it is a mechanical end stop, not a load-holding brake. The ACPJ series is discontinued - the current-production drop-in is ACEJ16X60 in the ISO 21287 family, so confirm mounting dimensions against the DIN-standard ACP footprint before swapping.
