This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ16X20-10, 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 ACPJ16X20-10
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ16X20-10 is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø16mm bore and 20mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ16X20-10 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X20-10
The ACPJ16X20-10 is a double acting compact cylinder with an adjustable stroke: a stop screw trims the 20 mm extend stroke by up to 10 mm on site, giving a usable range of 10-20 mm. Its short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding where a full-length body will not fit.
Built on a hard-anodized aluminium body with an S45C hard-chrome rod, it runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi) and 30-500 mm/s, with a fixed TPU bumper at each end. Note that the adjuster is a mechanical end stop only - on air loss the piston still drifts, so it is not a load-holding brake. This model is discontinued; the current-production replacement is the ACEJ16X20, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X20-10 (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 ACPJ16X20-10 Is Used
Packaging line ejection
Mounted under a conveyor, the 16 mm bore kicks light cartons or blisters off the belt at 30-500 mm/s, fitting the narrow space under the frame.
Gantry drop check
With the optional -S magnet and a CMSE switch, the trimmed end position signals part presence on an electronics assembly gantry.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X20-10 with the ACEJ16X20-10
The 10 mm window shortens the extend stroke only - it cannot lengthen it past 20 mm. FA/FB flange and LB foot mountings bolt to the ISO 21287 face, and the optional -S magnet enables CMSE / DMSE switches (this version has no magnet, so no sensor can be mounted). Order the ACEJ16X20 as the current direct replacement.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X20-10
- ✓ 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 ACPJ16X20-10 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. Operating pressure is 0.15-1.0 MPa (22-145 psi) with proof pressure of 1.5 MPa (215 psi), and speed ranges 30-500 mm/s.
The -10 code sets a 10 mm window: an external stop screw shortens the 20 mm extend stroke to any length from 10 to 20 mm, and a fixed TPU bumper decelerates the piston at both ends. The ACPJ16X20-10 is discontinued; the ACEJ16X20 is the current ISO 21287 direct with the same bore, stroke and force class - confirm its mounting dimensions before swapping.
