This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ16X40-10B, 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 ACPJ16X40-10B
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ16X40-10B is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø16mm bore and 40mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ16X40-10B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X40-10B
The ACPJ16X40-10B is a double acting compact cylinder with an adjustable stroke: an external stop screw trims the 40 mm extend stroke by up to 10 mm, giving a usable range of 30-40 mm on site. 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. 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.
Plan on roughly 60 N (about 6 kg) of real working force at 0.5 MPa rather than the full rating, which corresponds to lifting about 5 kg vertically with a 2:1 margin. The hard-anodized aluminium body carries an S45C hard-chrome rod with a fixed TPU bumper at each end, and the B code gives a male rod thread. Note this model is discontinued: the current-production drop-in is the ACEJ16X40, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X40-10B (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 ACPJ16X40-10B Is Used
PCB fixture clamping
Holds small circuit-board nests in a test jig with about 60 N of usable clamping force, the stop screw letting you trim the 40 mm stroke down to 30 mm for shallow fixtures.
Small-part ejection
Pushes machined pins off a micro-assembly nest at up to 500 mm/s; the male rod thread (B code) accepts a knuckle for angled ejection.
Gate interlock on packaging lines
Slides a guard latch on a compact carton machine; order the -S magnet version to add CMSE / DMSE switches for end-of-stroke confirmation.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X40-10B with the ACEJ16X40-10B
Size the bore both ways: the 12 mm bore gives only 56.5 N push at 0.5 MPa, while the 20 mm bore reaches 157.1 N, so 16 mm at 100.5 N sits in the middle for light clamping and positioning. The 10 mm adjust window suits fixtures where the final stop position is tuned during commissioning; remember the stop is a mechanical end stop only, and the piston drifts if air is lost. Mounting uses FA/FB flanges or LB feet on the ISO 21287 face, and if you need position sensing, order the -S version with the optional magnet for CMSE / DMSE switches - this B-coded model has no magnet fitted. For new projects, specify the ACEJ16X40 instead.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X40-10B
- ✓ 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 ACPJ16X40-10B 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 -10 code gives a 10 mm adjustment window, so the extend stroke can be trimmed anywhere between 30 and 40 mm with the external stop screw. It runs on air filtered to 40 um at 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, with an M5x0.8 port and an 8 mm male-thread rod.
Order the ACEJ16X40, the current-production ISO 21287 successor made by swapping the P for an E. It matches the same 16 mm bore, 40 mm stroke and force class with the same short-body format and mounting family (FA/FB flange, LB foot). Because the ACP was built to a DIN standard, confirm the ISO 21287 mounting dimensions against your fixture before swapping. If you need position sensing on the replacement, choose the -S code so the optional magnet is fitted for CMSE / DMSE switches.
