This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ16X110-50, 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 ACPJ16X110-50
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ16X110-50 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 ACEJ16X110-50 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X110-50
The ACPJ16X110-50 is a double acting compact cylinder with an adjustable extend stroke: a 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. Note the 110 mm stroke is longer than the 75 mm standard maximum for bore 16, so this is a made-to-order build.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight jigs and guard-mounted tooling. A hard-anodized aluminium body carries an S45C hard-chrome rod, with a fixed TPU bumper at each end and speeds of 30-500 mm/s. This model has no magnet (the optional -S code adds one for CMSE / DMSE switches) and is now discontinued: the current-production replacement is the ACEJ16X110, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X110-50 (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 ACPJ16X110-50 Is Used
Packaging line reject gates
Kicking underweight cartons off a checkweigher conveyor, with the trimmed extend stroke set so the gate clears the belt exactly and the fixed TPU bumper absorbs the return impact.
Lab fixture clamping
Clamping sample trays inside a compact test-rig guard where a full-length profile cylinder will not fit, using the FA flange mount and about 5 kg of practical vertical capacity.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X110-50 with the ACEJ16X110-50
The stop screw only shortens the extend stroke and is not a mid-stroke lock, so the rod can still drift if air is lost; do not use it to hold a load. FA/FB flange and LB foot mountings bolt to the standard face. If you need position sensing, order the -S variant with the optional magnet. For new designs, specify the ACEJ16X110 instead - this model is discontinued.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X110-50
- ✓ 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 ACPJ16X110-50 FAQ
The -50 code is a 50 mm adjustment window: an external stop screw shortens the 110 mm extend stroke to any length from 60 to 110 mm. It shortens the stroke only - it never lengthens it, and it is a mechanical end stop, not a load-holding lock. The 110 mm stroke is a made-to-order length because the bore 16 standard maximum is 75 mm.
Only if the optional -S magnet is ordered - this version (no S code) has no magnet, so CMSE / DMSE reed or solid-state switches cannot be mounted. The ACPJ family is discontinued; the current-production direct is the ACEJ16X110 (P changed to E), in the same bore, stroke and force class. Because the ACP is DIN-standard, confirm the ISO 21287 mounting dimensions of the ACEJ before swapping it into your fixture.
