This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ16X120-75B, 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 ACPJ16X120-75B
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ16X120-75B is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø16mm bore and 120mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ16X120-75B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X120-75B
This double acting ACPJ16X120-75B is a discontinued DIN-standard compact cylinder with an adjustable extend stroke: a stop screw trims the 120 mm stroke by up to 75 mm, giving a usable range of 45-120 mm. The 16 mm bore delivers 100.5 N push and 75.4 N pull at 0.5 MPa, 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 fits tight jigs and guarding where a full-length body cannot. Note the 120 mm stroke exceeds the 75 mm standard maximum for bore 16, so this is a made-to-order stroke.
The male rod thread (B code) bolts to I/Y knuckles on the ISO 21287 face, with FA/FB flange or LB foot options. A fixed TPU bumper sits at both ends and only decelerates the piston - it never locks or holds a load, and on air loss the piston still drifts. As a rule of thumb, plan for about 60 N (roughly 6 kg vertical) of real work at 0.5 MPa rather than the full rating. The magnet is not fitted on this version; order the -S code for CMSE / DMSE switch compatibility. For new projects, the current-production drop-in is ACEJ16X120 - confirm ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X120-75B (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 ACPJ16X120-75B Is Used
Compact jig clamping
The 45-120 mm adjustable range and short body let a fixture builder trim clamping travel on small aluminium brackets without redesigning the jig.
Packaging line kickers
100.5 N push at 0.5 MPa is enough to divert lightweight cartons on a packaging conveyor, with the stop screw set to the exact divert depth.
Lab sample press
The 16 mm bore's gentle 75.4 N pull retracts cleanly for small-bottle capping or sample-press stations where higher forces would crush the part.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X120-75B with the ACEJ16X120-75B
Size both ways: if 100.5 N push at 0.5 MPa is marginal, step up to the 20 mm bore for 157.1 N; if the load is light, the 12 mm bore gives 56.5 N in a smaller package. Match the male rod thread to an I/Y knuckle, and pick FA/FB flange or LB foot mounting to suit the fixture. If you need position feedback, order the -S magnet version - without it no CMSE / DMSE switch can be mounted. The stop screw is an end stop only, not a mid-stroke lock. This model is discontinued; the ACEJ16X120 is the current drop-in, so verify ISO 21287 mounting dimensions before ordering.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X120-75B
- ✓ 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 ACPJ16X120-75B 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 -75 code is a 75 mm adjustment window: a stop screw shortens the 120 mm extend stroke by up to 75 mm, so the usable range is 45-120 mm. The 120 mm stroke is made to order, since the bore 16 standard maximum is 75 mm. Operating pressure is 0.15-1.0 MPa (22-145 psi) and speed is 30-500 mm/s.
It is a short-body compact cylinder with a hard-anodized aluminium body, S45C hard-chrome rod, M5x0.8 ports and a fixed TPU bumper at both ends that only decelerates the piston. The body saves about 50% of the mounting length of an ISO 15552 profile cylinder. This ACPJ is discontinued; the current-production drop-in is the ACEJ16X120 - confirm the ISO 21287 mounting dimensions before swapping, because the ACP is DIN-standard.
