This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED20X50SB, 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 ACPD20X50SB
The AirTAC ACPD Double Rod Compact Cylinder ACPD20X50SB is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø20mm bore and 50mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED20X50SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD20X50SB
Double acting and double rod, the ACPD20X50SB pushes a 20 mm bore through a 50 mm stroke with a rod leaving both covers, so the force is identical in each direction: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa. The through-rod resists rotation and light side load, gives a symmetric mount, and lets the rear rod carry a sensor flag, while fixed TPU bumpers pad both ends of travel. Speed range is 30-500 mm/s across 0.15-1.0 MPa (22-145 psi) of clean, 40 um filtered air.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures and guarding where a full-length body will not fit. This unit carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke signals. Note that it is discontinued: the current-production direct is the ACED20X50, and buyers should confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED20X50SB (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 ACPD20X50SB Is Used
Pick-and-place gantry slide
The through-rod drives a small slide on a PCB handling gantry, where the rear rod carries a flag for CMSE switch position feedback and the 50 mm stroke matches the transfer pitch.
Lab sample press
117.8 N in both directions seats sample vials in an analytical instrument fixture, and the short body fits inside the instrument enclosure where a full-length profile cylinder cannot.
Carton push-off station
On a packaging line the symmetric double-rod mount pushes light cartons off a conveyor stop, with the fixed TPU bumper softening each end of the 50 mm travel at up to 500 mm/s.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD20X50SB with the ACED20X50SB
At 117.8 N per direction, the 20 mm bore sits between the 16 mm (75.4 N) and 25 mm (206.2 N) options at 0.5 MPa. Step down if your tooling mass is light, step up if cycle forces approach the rating. The 50 mm stroke is within the 100 mm standard limit for this bore, so no made-to-order build is needed. The B code gives a male 10 mm rod thread; blank would be female M6x1.0. FA/FB flange or LB foot mounts bolt to the standard face, and the -S magnet on this model pairs with CMSE / DMSE switches. Remember a plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check for held loads. Order the ACED20X50 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACED20X50SB
- ✓ 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 ACPD20X50SB FAQ
Because a rod exits both covers, force is equal in both directions: 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 pressure 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.
The hard-anodized aluminium body follows the short ISO 21287-class format, saving about 50% of the mounting length of an ISO 15552 profile cylinder, with FA/FB flange and LB foot options. This model includes the optional -S magnet, so CMSE reed or DMSE solid-state switches mount directly in the body slot. The model is discontinued; the ACED20X50 is the current direct, so confirm ISO 21287 mounting dimensions before ordering.
