This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED100X50B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED100X50B 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 ACPD100X50B
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD100X50B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø100mm bore and 50mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED100X50B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD100X50B
A double acting, double-rod compact cylinder, the ACPD100X50B pushes a 100 mm piston through a 50 mm stroke with a rod leaving both covers. Because each side works on the rod-side area, output is identical in either direction: 3681.6 N at 0.5 MPa and 5154.2 N at 0.7 MPa. The 25 mm through-rod shrugs off rotation and side load, and its rear end doubles as a mount for a sensor flag. A fixed TPU bumper sits at each end, and speed spans 30-500 mm/s.
The short ISO 21287-class body cuts roughly 50% of the mounting length of an ISO 15552 profile cylinder, so a 50 mm-stroke unit slots into presses, gantries and guarding where a full-length body cannot. On a 0.5 MPa supply, halving the 375 kg thrust equivalent leaves about 188 kg of vertical lift capacity - enough headroom to hoist a heavy fixture or die segment with margin. Note this model is discontinued: the current-production drop-in is the ACED100X50, so confirm ISO 21287 mounting dimensions before ordering.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED100X50B (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 ACPD100X50B Is Used
Bench-top stamping press
The 3681.6 N bidirectional thrust at 0.5 MPa crimps and forms aluminium brackets on a short-stroke press head, and the 50% shorter body keeps the frame low.
Reciprocating conveyor pusher
Equal force in both directions lets the through-rod kick heavy cartons off a line and retract with the same authority, with the rear rod carrying a position flag.
Die cart clamp fixture
About 188 kg of vertical lift capability at 0.5 MPa with a 2:1 margin seats and releases mold clamps in a toolroom, guided by the 25 mm rod against side load.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD100X50B with the ACED100X50B
At bore 100 the ACPD delivers 3681.6 N both ways at 0.5 MPa - far above the 881.2 N of a bore 50 unit and the 2356.2 N of bore 80, so step down if your load is lighter. Plan on roughly 2209 N (about 60% of rating) for real work at 0.5 MPa. The plain piston drifts when air is lost, so add a rod lock or pilot check for a held load. This B-code version has a male rod thread and PT ports; FA/FB flange and LB foot mountings bolt to the ISO 21287 face. No magnet is fitted - order the -S code if you need CMSE / DMSE switch positions. As the ACPD line is discontinued, specify the ACED100X50 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACED100X50B
- ✓ 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 ACPD100X50B FAQ
Output is equal both ways because the rod-side area works on each stroke: 3681.6 N at 0.5 MPa and 5154.2 N at 0.7 MPa, peaking at 750.8 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, air filtered to 40 um, from -20 to +70 C at 30-500 mm/s.
This model is no longer in production; the current drop-in is the ACED100X50 (swap the P for an E), matching the same 100 mm bore, 50 mm stroke and force class - confirm ISO 21287 mounting dimensions before swapping. The cylinder uses a hard-anodized aluminium body, an S45C hard-chrome 25 mm rod with a male thread, 1/4" PT ports, fixed TPU bumpers at both ends, and an optional -S magnet for CMSE / DMSE switches (not fitted on this code).
