This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ16X110-50S, 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 ACPJ16X110-50S
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ16X110-50S is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø16mm bore and 110mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ16X110-50S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X110-50S
The ACPJ16X110-50S is a double acting compact cylinder with an adjustable extend stroke: the -50 stop screw trims the 110 mm stroke by up to 50 mm on site, giving a usable range of 60-110 mm. Air pushes the piston out and pulls it back, so no spring is involved. 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. The 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. A fixed TPU bumper sits at both ends.
Note that the 110 mm stroke exceeds the 75 mm maximum standard stroke for bore 16, so this unit is a non-standard, made-to-order build. The 110 mm length also means the -S magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clamped anywhere along the body for end-of-travel signals. For planning, treat roughly 60 N (about 6 kg lifted) as the practical working force at 0.5 MPa rather than the full 100.5 N rating. This model is discontinued: the current-production replacement is the ACEJ16X110, and buyers should confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X110-50S (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 ACPJ16X110-50S Is Used
Fixture clamping on CNC pallets
The 60-110 mm adjustable window lets a machinist dial the clamp stroke to each pallet, and the 100.5 N push at 0.5 MPa suits light aluminum part hold-down.
Reject pusher with position feedback
With the fitted -S magnet, CMSE switches flag extend and retract on a packaging line reject chute, while the 75.4 N pull retracts the pusher clear of product flow.
Compact press for electronics assembly
A short-body cylinder trims connector crimp or snap-fit presses inside a slim gantry, using about 140.7 N push at 0.7 MPa for small plastic components.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X110-50S with the ACEJ16X110-50S
Size the bore by load: if 100.5 N push at 0.5 MPa is marginal, step up to bore 20 for 157.1 N; if the load is light, bore 12 gives 56.5 N at lower air use. Keep in mind the stop screw is a mechanical end stop only - on air loss the piston still drifts, so it is not a mid-stroke lock or load-holding brake. FA/FB flanges and LB feet bolt to the standard face, and I/Y rod knuckles suit the M4x0.7 female rod thread. Order the -S code (as here) whenever CMSE / DMSE switches are needed. For new designs, specify the ACEJ16X110 instead - same bore, stroke and force class, currently in production.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X110-50S
- ✓ 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 ACPJ16X110-50S 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; theoretical maximum is 20.5 kgf at 1.0 MPa. The -50 code gives a 50 mm adjustment window, so the 110 mm extend stroke can be trimmed anywhere between 60 and 110 mm with the stop screw. Operating pressure is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, with a fixed TPU bumper at both ends.
No - the ACPJ family is discontinued. The current-production drop-in is the ACEJ16X110 (swap the P for an E): same 16 mm bore, 110 mm stroke and force class in an ISO 21287 short body. Because the ACP is DIN-standard, confirm the ISO 21287 mounting dimensions before swapping. This unit carries the optional -S magnet, so CMSE / DMSE switches mount directly; the port is M5x0.8.
