This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED20X35B, 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 ACPD20X35B
The AirTAC ACPD Double Rod Compact Cylinder ACPD20X35B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø20mm bore and 35mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED20X35B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD20X35B
A double acting, double-rod compact cylinder with a 20 mm bore and 35 mm stroke, the ACPD20X35B pushes a piston rod out of both covers, so the through-rod delivers 117.8 N in each direction at 0.5 MPa (164.9 N at 0.7 MPa) because both strokes work on the rod-side area. The male rod thread (B code) bolts straight to tooling, and the back-end rod can carry a sensor flag or a second fixture. Its short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight jigs and guarding where a full-length body will not fit.
A fixed TPU bumper sits at each end to decelerate the piston. Note this model is discontinued - the current-production replacement is the ACED20X35 (swap the P for an E), a direct in the same bore, stroke and force class; confirm the ISO 21287 mounting dimensions before swapping. If you need position sensing, order the optional -S magnet code to enable CMSE / DMSE switches - without -S there is no magnet fitted.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED20X35B (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 ACPD20X35B Is Used
Pick-and-place on small assembly cells
The 117.8 N bidirectional force and male rod thread let one cylinder both extend and retract a gripper arm on electronics assembly fixtures, with the back rod carrying a position flag.
Clamping in tight machining fixtures
With a body about 50% shorter than an ISO 15552 profile cylinder, the 35 mm stroke clamps small aluminium workpieces inside crowded CNC jigs where space is limited.
Symmetric slide actuation on test rigs
The through-rod resists rotation and side load, driving a test head both ways at equal 117.8 N force; add the optional -S magnet and CMSE / DMSE switches for end-of-stroke signalling.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD20X35B with the ACED20X35B
At 20 mm bore you get 117.8 N both ways at 0.5 MPa. If your load needs more, step up to the 25 mm bore (206.2 N at 0.5 MPa); if less force and a smaller envelope work, the 16 mm bore gives 75.4 N. The 35 mm stroke sits well inside the 100 mm maximum standard stroke for this bore, so it is a catalogue item, not a made-to-order build. This through-rod version does not hold position when air is lost - add a rod lock or pilot check valve for a held load. Match FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot or FTC mounting to your fixture, and remember the magnet only comes with the -S code. Since the ACPD is discontinued, order the ACED20X35 as the current direct and verify ISO 21287 mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACED20X35B
- ✓ 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 ACPD20X35B FAQ
Yes - because a rod exits both covers, both strokes use the rod-side area, so force is equal both ways: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa, with a maximum of about 24 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 port is M5x0.8. In practice, budget around 70 N of usable force at 0.5 MPa, roughly a 6 kg vertical lift with margin.
Order the ACED20X35, the current-production ISO 21287 successor: swap the P for an E and you get the same 20 mm bore, 35 mm stroke and force class in a short compact body with hard-anodized aluminium construction and an S45C hard-chrome rod. Before swapping, confirm the ISO 21287 mounting dimensions against your fixture, since the ACP was built to a DIN-standard footprint. Mounting options (FA/FB flange, LB foot, CA/CB clevis, CR, SDB, FTC) and the optional -S magnet for CMSE / DMSE switches carry over as ordering choices.
