This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ20X175-100SB, 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 ACPJ20X175-100SB
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ20X175-100SB is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø20mm bore and 175mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ20X175-100SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X175-100SB
This is a double acting, adjustable-stroke compact cylinder with a 20 mm bore and a made-to-order 175 mm stroke, trimmed on site by a stop screw within the 100 mm window of the -100 code, so the usable extend range is 75-175 mm. Air filtered to 40 um drives it at 0.15-1.0 MPa (22-145 psi) with speeds of 30-500 mm/s, and a fixed TPU bumper sits at each end. The B code gives a male rod thread on the 10 mm rod, and the S code means the optional -S magnet is fitted, so CMSE / DMSE reed or solid-state switches can be mounted for end-of-stroke sensing.
The hard-anodized aluminium body is an ISO 21287 class short build that saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits deep pockets, sliding guards and gantry clamps. Note that the stop screw only shortens the extend stroke and is not a mid-stroke lock: on air loss the piston still drifts. This model is discontinued; the current-production replacement is the ACEJ20X175, a direct in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X175-100SB (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 (Ø20mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 118 N |
| 0.7 MPa | 165 N |
| Max (@1.0 MPa) | 24 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 ACPJ20X175-100SB Is Used
Ejector on a small packaging machine
At 30-500 mm/s the rod kicks finished cartons off a conveyor lane; the male rod thread bolts straight to a pusher plate, and the fitted magnet feeds a DMSE switch to confirm return.
Stopper gate on an electronics assembly line
The short ISO 21287 class body fits under a low PCB transfer rail where a full-length ISO 15552 profile cylinder would not, extending up to 175 mm to block the flow.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X175-100SB with the ACEJ20X175-100SB
The 175 mm stroke exceeds the 100 mm maximum standard stroke for bore 20, so it is a non-standard, made-to-order build - plan lead time accordingly. Mounting options are FA/FB flange or LB foot, and the male rod thread (B code) pairs with I/Y knuckles. For sensing, this unit already carries the optional -S magnet for CMSE / DMSE switches. When ordering new, specify the ACEJ20X175 instead, the current ISO 21287 successor.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X175-100SB
- ✓ 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 ACPJ20X175-100SB FAQ
It is double acting with a 20 mm bore, 10 mm male-thread rod, M5x0.8 ports, 0.15-1.0 MPa (22-145 psi) operating pressure, 1.5 MPa (215 psi) proof pressure, -20 to +70 C, 30-500 mm/s, and a fixed TPU bumper at both ends. The 175 mm stroke is a made-to-order size, adjustable down to 75 mm via the 100 mm window.
Order the ACEJ20X175: swap the P for an E and you get the current-production ISO 21287 replacement in the same bore, stroke and force class. Because the ACP is DIN-standard, confirm the ISO 21287 mounting dimensions (FA/FB flange or LB foot faces) before swapping. The ACEJ keeps the short compact body, about 50% shorter in mounting length than an ISO 15552 profile cylinder, and accepts the same CMSE / DMSE switch family when the -S magnet is specified.
