This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED20X20SB, 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 ACPD20X20SB
The AirTAC ACPD Double Rod Compact Cylinder ACPD20X20SB is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø20mm bore and 20mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED20X20SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD20X20SB
This is a double acting, double-rod compact cylinder in the discontinued AirTAC ACP DIN-standard series. A 10 mm rod exits both covers, so the 20 mm bore delivers an equal 117.8 N at 0.5 MPa in each direction - there is no larger push than pull, because both strokes work on the rod-side area. The male rod thread (B code) bolts straight to tooling, and the through-rod resists rotation and light side load while the free back-end rod can carry a sensor flag. This unit carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be mounted for end-of-stroke sensing.
The hard-anodized aluminium body with S45C hard-chrome rod saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight jigs and guard-mounted fixtures. A fixed TPU bumper sits at both ends and simply decelerates the piston - it never holds or brakes a load, so plan a rod lock or pilot check if the position must survive a loss of air. Note that the ACPD family is no longer in production: the current direct is the ISO 21287 ACED20X20, same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping, since the ACP is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED20X20SB (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 ACPD20X20SB Is Used
Fixture clamping on CNC jigs
The 117.8 N per side at 0.5 MPa clamps small aluminium brackets in drilling jigs, and the male rod thread takes a knuckle for fast fixture swaps.
Push-pull slide mechanisms
Equal force in both directions makes the through-rod ideal for reciprocating slides on packaging machines, where the back rod drives a sensor flag.
Position-sensed ejectors
With the -S magnet fitted, CMSE or DMSE switches confirm ejector home and out positions on electronics assembly stations at up to 500 mm/s.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD20X20SB with the ACED20X20SB
At 117.8 N per side at 0.5 MPa (164.9 N at 0.7 MPa), the 20 mm bore is a light-duty size: step down to the 16 mm bore at 75.4 N for small gates and fixtures, or up to the 25 mm bore at 206.2 N when clamping forces rise. The 20 mm stroke is well inside the 100 mm maximum standard stroke for this bore. Mount with FA/FB flange or LB foot brackets, and remember this model already includes the -S magnet for CMSE / DMSE switches. For new designs, order the ACED20X20 instead - the ACPD is discontinued.
Replacement checklist
- ✓ Current-production ACE → ACED20X20SB
- ✓ 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 ACPD20X20SB FAQ
Because it is a double-rod cylinder, force is equal in both directions: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa per side, with a maximum of 24.0 kgf (240 N) 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 rod is 10 mm with a male thread.
The ACPD series is out of production. The current direct is the ACED20X20, the ISO 21287 successor in the same bore, stroke and force class. Before swapping, confirm the ISO 21287 mounting dimensions, since the ACP was built to the older DIN-standard compact format. Mounting brackets and the optional -S magnet for CMSE / DMSE sensing carry over in function.
