This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ16X150-50S, 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 ACPJ16X150-50S
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ16X150-50S is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø16mm bore and 150mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ16X150-50S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X150-50S
This is a double acting, adjustable-stroke compact cylinder in the discontinued AirTAC ACPJ family. 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, with a theoretical peak of 20.5 kgf at 1.0 MPa. The -50 code gives a 50 mm adjustment window: a stop screw trims the extend stroke anywhere in a 100-150 mm range on site, so one cylinder covers several jig positions. The 150 mm stroke exceeds the 75 mm standard maximum for bore 16, so it is a made-to-order build. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be fitted for end-of-stroke sensing.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which matters in tight guards and slide fixtures. A hard-anodized aluminium body with an S45C hard-chrome rod, fixed TPU bumpers at both ends and a 30-500 mm/s speed band round out the spec. A practical sizing rule: at 0.5 MPa plan on about 60 N of usable push, which lifts roughly 5 kg vertically with a 2:1 margin. Note that ACPJ is discontinued - the current-production drop-in is the ACEJ16X150, and you should confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X150-50S (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 ACPJ16X150-50S Is Used
Small-part ejection from plastic moulds
The 100.5 N push at 0.5 MPa is enough to kick light moulded clips off an ejector plate, and the 100-150 mm adjustable range lets one cylinder serve several mould heights.
Product divert on a bottling line
A pusher paddle on the M4x0.7 female rod thread deflects bottles between lanes; the -S magnet with a CMSE switch confirms the retract position before the next bottle arrives.
Sample slide in a lab analyser
Moving a 5 kg-or-less sample tray vertically fits the roughly 60 N usable push at 0.5 MPa, and the compact short body slots into instrument frames where a full-length profile cylinder cannot.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X150-50S with the ACEJ16X150-50S
Size against neighbours: the 12 mm bore gives 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 mid-range for light clamping and slide duty. The stop screw only shortens the extend stroke within the 50 mm window and does not hold a load - on air loss the piston still drifts, so add a separate lock if position must be retained. FA/FB flange and LB foot mountings bolt to the standard face, and this -S version already carries the magnet for CMSE / DMSE switches. For new designs, order the ACEJ16X150 instead, since ACPJ is discontinued; verify ISO 21287 mounting dimensions before the swap.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X150-50S
- ✓ 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 ACPJ16X150-50S FAQ
At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa that rises to 140.7 N push and 105.6 N pull, with a theoretical maximum of 20.5 kgf at 1.0 MPa. It is double acting with a 50 mm adjustment window (usable stroke 100-150 mm), M5x0.8 ports, an M4x0.7 female rod thread, 0.15-1.0 MPa (22-145 psi) operating pressure, 30-500 mm/s speed and fixed TPU bumpers. The 150 mm stroke is a made-to-order length above the 75 mm standard maximum for bore 16.
Order the ACEJ16X150, the current-production ISO 21287 successor: swap the P for an E and you get the same 16 mm bore, 150 mm stroke class and force band in a matching short body. Because the ACPJ follows the DIN-standard footprint, confirm the ISO 21287 mounting dimensions against your fixture before swapping. The ACEJ keeps the same FA/FB flange and LB foot mounting family and accepts the same CMSE / DMSE switch range when the -S magnet is specified.
