This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED20X70B, 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 ACPD20X70B
The AirTAC ACPD Double Rod Compact Cylinder ACPD20X70B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø20mm bore and 70mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED20X70B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD20X70B
A double acting compact cylinder with a rod leaving both covers, the ACPD20X70B pushes and pulls with identical output: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa in each direction, because both strokes work on the rod-side area. The through-rod resists rotation and side load, gives a symmetric mount, and the rear rod can carry a sensor flag. A fixed TPU bumper sits at each end, and speed runs 30-500 mm/s at 0.15-1.0 MPa (22-145 psi).
The hard-anodized aluminium body keeps the mounting length roughly 50% shorter than an ISO 15552 profile cylinder, so this 70 mm stroke unit slots into tight jigs and guarding where a full-length body cannot. Note this model is discontinued: the current-production direct is the ISO 21287 ACED20X70, so confirm mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED20X70B (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).

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 ACPD20X70B Is Used
Symmetric jig clamping
The 117.8 N equal push and pull clamps a small aluminum bracket from either side of a drilling fixture, with the through-rod keeping the tool plate square.
Bidirectional pusher on packaging lines
One air line drives cartons off a conveyor in either direction at 164.9 N, since both strokes deliver the same rod-side force.
Flag carrier for dual-end sensing
With the optional -S magnet fitted, the rear rod carries a second flag so CMSE or DMSE switches confirm both end positions on a test station.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD20X70B with the ACED20X70B
At 117.8 N per direction, bore 20 suits light clamping and transfer tasks; step down to bore 16 (75.4 N) for gentler loads or up to bore 25 (206.2 N) when more force is needed. The 70 mm stroke sits inside the 100 mm maximum standard stroke for this bore, so no made-to-order build is required. The B code gives a male M6x1.0 rod thread; a plain code would give female. No magnet is fitted, so no CMSE or DMSE switch can be used - order the -S code for position sensing. Since the piston drifts when air is lost, add a rod lock or pilot check for held loads. Replacement: ACED20X70.
Replacement checklist
- ✓ Current-production ACE → ACED20X70B
- ✓ 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 ACPD20X70B FAQ
Yes - the double-rod design works on the rod-side area both ways, so output is equal in extend and retract: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa, peaking at 24.0 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, with a fixed TPU bumper at each end.
No - the ACPD family is discontinued. The current-production replacement is the ISO 21287 ACED20X70, which matches the same 20 mm bore, 70 mm stroke and force class. Because the ACP is DIN-standard, confirm the ISO 21287 mounting dimensions and FA/FB or LB hole pattern before swapping.
