This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED20X45SB, 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 ACPD20X45SB
The AirTAC ACPD Double Rod Compact Cylinder ACPD20X45SB is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø20mm bore and 45mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED20X45SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD20X45SB
A double acting, double-rod compact cylinder built to the DIN-standard ACP layout, the ACPD20X45SB pushes and pulls with the same 117.8 N at 0.5 MPa (164.9 N at 0.7 MPa) because a 10 mm rod exits both covers and both strokes use the rod-side area. The 20 mm bore runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof tested to 1.5 MPa (215 psi), from -20 to +70 C at 30-500 mm/s. The male rod thread (B code) and the optional -S magnet for CMSE / DMSE switches are already in this model code.
The hard-anodized aluminium body with an S45C hard-chrome rod is an ISO 21287-class short build that saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight pick-and-place gantries. A fixed TPU bumper sits at both ends. Note: this model is discontinued - the current-production direct is the ACED20X45, same bore, stroke and force class; confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED20X45SB (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 ACPD20X45SB Is Used
Reciprocating transfer arm
The double rod gives identical 117.8 N push and pull at 0.5 MPa, so a small electronics-line shuttle accelerates the same both ways at 30-500 mm/s without a return-stroke derate.
Position-flagged test station
With the -S magnet already fitted, CMSE or DMSE switches on either cover report end positions of a 45 mm gauge stroke, while the rear rod drives a second indicator flag.
Compact rotary-index jig
The short ISO 21287-class body halves the length of an ISO 15552 profile cylinder, letting the 20 mm bore clamp parts inside a crowded dial-table fixture where space is fixed.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD20X45SB with the ACED20X45SB
For a 45 mm stroke needing equal force in both directions, the 20 mm bore gives 117.8 N at 0.5 MPa each way; step down to a 16 mm bore (75.4 N) for lighter tooling or up to a 25 mm bore (206.2 N) if the load grows. The through-rod resists rotation and side load, and the rear rod can carry a sensor flag. This unit carries the -S magnet, so CMSE / DMSE switches mount directly; FA/FB flange, LB foot and CA/CB clevis brackets bolt to the same face. It will not hold position if air is lost - add a rod lock or pilot check for a held load. Replacement: ACED20X45 (confirm ISO 21287 dimensions).
Replacement checklist
- ✓ Current-production ACE → ACED20X45SB
- ✓ 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 ACPD20X45SB FAQ
Because it is a double-rod cylinder, force is equal both ways: 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. Both strokes use the rod-side area of the 20 mm bore, so there is no push-versus-pull difference. Operating range is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, port M5x0.8, rod 10 mm with a male thread.
The hard-anodized aluminium body is an ISO 21287-class short build that saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at each end. The ACPD family is discontinued; the current-production direct is the ACED20X45 (swap the P for an E), which matches the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before ordering.
