This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ16X100-50, 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 ACPJ16X100-50
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ16X100-50 is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø16mm bore and 100mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ16X100-50 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X100-50
The ACPJ16X100-50 is a double acting compact cylinder with an adjustable stroke: a stop screw trims the 100 mm extend stroke by up to 50 mm, giving a usable range of 50-100 mm on site. Its 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, with a theoretical peak of 20.5 kgf at 1.0 MPa. The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding where a full-length body cannot. Note that the 100 mm stroke exceeds the 75 mm standard maximum for bore 16, so this is a made-to-order stroke.
Practical sizing: plan on about 60 N of real work at 0.5 MPa (roughly 60% of the rated push), which lifts about 5 kg vertically - halve that to about 2.5 kg if you want a 2:1 margin on a vertical lift. The hard-anodized aluminium body carries an S45C hard-chrome rod, fixed TPU bumpers sit at both ends, and the rod end is female M4x0.7 with M5x0.8 ports. This model is discontinued; the current-production drop-in is the ACEJ16X100 (same bore, stroke and force class) - confirm ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X100-50 (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 ACPJ16X100-50 Is Used
Small jig clamping
Clamps fixture plates on an electronics assembly jig where the 50-100 mm trimmed stroke and 100.5 N push at 0.5 MPa suit light clamping of PCB carriers.
Gate and guard actuation
Swings or pushes small interlock gates on packaging machines; the short body fits behind guarding, and the -S magnet version accepts CMSE / DMSE switches for end-position feedback.
Bench-top press assist
Adds about 10 kg of push force to a manual lab or workshop press station, with the 50 mm adjustment window letting operators dial the press stroke per part.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X100-50 with the ACEJ16X100-50
Size both ways: if 100.5 N push at 0.5 MPa is marginal for your load, step up to bore 20 for 157.1 N push; if the load is light, bore 12 gives 56.5 N in a smaller envelope. The stop screw shortens the extend stroke only - it is a mechanical end stop, not a mid-stroke lock, so on air loss the piston still drifts and cannot hold a load. Mounting uses FA/FB flanges or LB feet on the ISO 21287 face. No magnet is fitted on this code (no S), so no CMSE / DMSE switch can be mounted - order the -S version if sensing is needed. For new projects, specify the ACEJ16X100 instead.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X100-50
- ✓ 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 ACPJ16X100-50 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 stop screw trims the 100 mm extend stroke anywhere in a 50-100 mm range. The stroke is non-standard (bore 16 standard maximum is 75 mm), so it is made to order. Operating pressure is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s.
This model is discontinued. The current-production replacement is the ACEJ16X100 (swap the P for an E), a drop-in in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping because the ACP is DIN-standard. Sensing requires the optional -S magnet code, which enables CMSE / DMSE reed or solid-state switches; this unit (no S code) carries no magnet, so no switch can be mounted. Mounting options are FA/FB flanges and LB feet.
