This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED20X30SB, 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 ACPD20X30SB
The AirTAC ACPD Double Rod Compact Cylinder ACPD20X30SB is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø20mm bore and 30mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED20X30SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD20X30SB
A double acting compact cylinder with a rod leaving both covers, the ACPD20X30SB pushes and pulls with the same 117.8 N at 0.5 MPa (164.9 N at 0.7 MPa) because both strokes work on the rod-side area of the 20 mm bore. The through-rod resists rotation and light side load, gives a symmetric mount, and the rear rod can carry a sensor flag. A male rod thread (B code) and PT ports suit direct tooling attachment. This model is discontinued; the current-production direct is the ISO 21287 ACED20X30, so confirm mounting dimensions before swapping.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it fits tight jigs, guards and small gantries. This unit carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be mounted for end-of-stroke sensing. A fixed TPU bumper sits at each end, speed spans 30-500 mm/s, and pressure runs 0.15-1.0 MPa (22-145 psi).

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED20X30SB (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 |
Double-rod: a rod exits both covers, so output force is equal in both directions (rod-side area used).

Where the Airtac ACPD Double Rod Compact Cylinder ACPD20X30SB Is Used
Small-parts ejection
The rear rod doubles as an ejector on a 30 mm stroke, pushing finished bushings off an assembly nest with about 117.8 N per side at 0.5 MPa.
Position-flagged press station
With the -S magnet fitted, CMSE or DMSE switches confirm both end positions on a benchtop crimping fixture, while the through-rod keeps the tooling square.
Symmetric test clamp
Equal force in both directions lets a lab fixture grip and release a PCB carrier with identical 164.9 N at 0.7 MPa, no reverse-pressure plumbing needed.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD20X30SB with the ACED20X30SB
At 117.8 N per side, this 20 mm bore sits between the 16 mm (75.4 N) and 25 mm (206.2 N) double-rod sizes at 0.5 MPa; step up to 25 mm if your clamp needs more margin, or down to 16 mm for lighter ejection work. The 30 mm stroke is well inside the 100 mm standard limit for this bore. Choose the male-thread rod for knuckles and tooling, and remember a plain double-rod cylinder drifts when air is lost - add a rod lock or pilot check if the load must stay put. For new designs, order the ACED20X30 instead, as this ACPD version is discontinued.
Replacement checklist
- ✓ Current-production ACE → ACED20X30SB
- ✓ 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 ACPD20X30SB FAQ
Yes - because a rod exits both covers, both strokes use the rod-side area of the 20 mm bore, so force is equal in each direction: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa, with a maximum of 24.0 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, and the rod is 10 mm with a male thread.
The hard-anodized aluminium body follows the short DIN-standard compact format, saving about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at each end and M5x0.8 ports. The ACPD family is discontinued; the current direct is the ISO 21287 ACED20X30 - same bore, stroke and force class - so verify mounting dimensions before you swap.
