This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED100X20B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED100X20B in place of this model. 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 ACPD100X20B
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD100X20B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø100mm bore and 20mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED100X20B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD100X20B
This is a double acting, double-rod compact cylinder in the discontinued AirTAC ACPD series, with a 100 mm bore and a short 20 mm stroke. A 25 mm piston rod passes through both covers, so the working area is the rod-side annulus on each side and the output is identical in either direction: 3681.6 N at 0.5 MPa and 5154.2 N at 0.7 MPa. The male rod thread (B code) is M16x1.5, and the air port is 1/4" PT.
The hard-anodized aluminium body with an S45C hard-chrome rod keeps the mounting length about 50% shorter than an ISO 15552 profile cylinder, which matters in presses, gantries and fixture plates where every millimetre counts. Because the through-rod exits the rear cover too, you can carry a sensor flag or a second tool on the back end while the front rod does the work. A fixed TPU bumper sits at both ends, and speed runs 30-500 mm/s across 0.15-1.0 MPa (22-145 psi). At 0.5 MPa, plan on roughly 2209 N of usable push (about 60% of rating), which is around 375 kgf - so figure on lifting about 187 kg vertically with a 2:1 margin. Note this model is discontinued: the current-production drop-in is the ACED100X20, and you should confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED100X20B (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 (Ø100mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 3682 N |
| 0.7 MPa | 5154 N |
| Max (@1.0 MPa) | 751 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 ACPD100X20B Is Used
Benchtop crimping press
A 20 mm stroke is enough for terminal and connector crimping on an electronics assembly bench; the 3681.6 N both-way force lets one cylinder crimp on the downstroke and eject on the return.
Fixture clamping on a CNC jig
The through-rod clamps a workpiece from the front while the rear rod drives a witness flag, and the short body fits inside the jig envelope where a full-length cylinder would not.
Conveyor pusher arm
At a packaging line transfer point, the symmetric rod-side force pushes cartons off the belt in one direction and retracts the arm with identical force, with the TPU bumper absorbing end-of-stroke shock.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD100X20B with the ACED100X20B
For a 20 mm stroke doing symmetric push-pull work at this force class, the 100 mm bore delivers 3681.6 N both ways at 0.5 MPa. If your load needs under 881 N, step down to the 50 mm bore; if you need beyond 3681 N, there is no larger ACPD bore, so check the ACED range or a bigger frame. Remember the piston drifts when air is lost - add a rod lock or pilot check if the load must stay put. This unit has no magnet fitted; order the -S code if you want CMSE / DMSE switches. The direct replacement is the ACED100X20 - verify ISO 21287 mounting dimensions first.
Replacement checklist
- ✓ Current-production ACE → ACED100X20B
- ✓ 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 ACPD100X20B FAQ
Because it is a double-rod cylinder, force is equal in both directions: 3681.6 N at 0.5 MPa and 5154.2 N at 0.7 MPa on each stroke, using the rod-side area. The maximum force at 1.0 MPa is 750.8 kgf. 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 rod thread is male M16x1.5 with a 1/4" PT port.
The ACPD series is no longer in production; the current drop-in is the ACED100X20 (swap the P for an E), which matches the same 100 mm bore, 20 mm stroke and force class. The compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so confirm the ISO 21287 mounting dimensions before swapping. Mounting options in the family include FA/FB flange and LB foot, and the optional -S magnet enables CMSE / DMSE switches.
