This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED25X20B, 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 ACPD Double Rod Compact Cylinder ACPD25X20B
The AirTAC ACPD Double Rod Compact Cylinder ACPD25X20B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø25mm bore and 20mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED25X20B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD25X20B
A double acting compact cylinder with a rod through both covers, the ACPD25X20B pushes with the same 206.2 N at 0.5 MPa in each direction because both strokes work on the rod-side area. The 25 mm bore, 20 mm stroke and male rod thread (the B code) suit short-stroke tooling, and the through-rod resists rotation and side load while the rear rod can carry a sensor flag. A fixed TPU bumper sits at each end and speed spans 30-500 mm/s.
The hard-anodized aluminium body is an ISO 21287 short build, cutting roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and gantries. Note this model is discontinued: the current direct is the ACED25X20, so confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED25X20B (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 (Ø25mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 206 N |
| 0.7 MPa | 289 N |
| Max (@1.0 MPa) | 42 kgf |
Double-rod: a rod exits both covers, so output force is equal in both directions (rod-side area used).

Replacement mapping (swap P for E): ACP→ACE, ASP→ASE, ATP→ATE, ACPD→ACED, ACPJ→ACEJ. ACP-family: ACP (double acting), ASP / ATP (single acting push / pull), ACPD (double rod), ACPJ (double rod, adjustable stroke).
Where the Airtac ACPD Double Rod Compact Cylinder ACPD25X20B Is Used
Fixture clamping from both sides
The through-rod lets one cylinder clamp a machined aluminium bracket from two faces with an equal 206.2 N at 0.5 MPa on each side, halving part count in a drilling jig.
Packaging line pusher
A 20 mm stroke is enough to kick small cartons off a conveyor lane at up to 500 mm/s, and the symmetric double-rod mount keeps the pusher plate square to the belt.
Sensor flag carrier
In a small assembly press, the rear rod can mount a flag for a switch position check while the front rod does the work - order the -S code if you need the optional magnet for CMSE or DMSE switches.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD25X20B with the ACED25X20B
At 206.2 N per side at 0.5 MPa, this 25 mm bore sits between the 20 mm bore (117.8 N) and the 32 mm bore (345.6 N), so step up if your fixture needs more margin. Stroke 20 mm is well inside the 150 mm maximum standard for this bore. The B code gives a male rod thread; the port is M5x0.8. Remember the cylinder drifts when air is lost, so add a rod lock or pilot check for held loads. This unit is discontinued - the ACED25X20 is the current replacement in the same force class.
Replacement checklist
- ✓ Current-production ACE → ACED25X20B
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ACPD Double Rod Compact Cylinder ACPD25X20B FAQ
Yes - it is a double-rod cylinder, so both strokes use the rod-side area. Output is 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa, equal in each direction, with a maximum of 42 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, port M5x0.8, male rod thread, and the 20 mm stroke sits inside the 150 mm standard maximum for this bore.
The ACPD25X20B is discontinued. The current-production direct is the ACED25X20 (swap the P for an E) in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping since the ACP is DIN-standard. The body is hard-anodized aluminium with an S45C hard-chrome rod, about 50% shorter in mounting length than an ISO 15552 profile cylinder, with FA/FB flange or LB foot options and a fixed TPU bumper at each end. The magnet is only fitted when you order the optional -S code.
