This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED100X125SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED100X125SB 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 ACPD100X125SB
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD100X125SB is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø100mm bore and 125mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED100X125SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD100X125SB
This is a double acting, double-rod compact cylinder in the discontinued AirTAC ACP DIN-standard series: a 100 mm bore with a 125 mm stroke, a 25 mm rod leaving BOTH covers, and a male rod thread on the B code. Because each side of the piston sees the rod-side area, it delivers an identical 3681.6 N at 0.5 MPa and 5154.2 N at 0.7 MPa in push and pull - no derating for the return stroke. The 1/4" port feeds it, the S code means the magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke signalling.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why this force class fits gantries and press fixtures that cannot swallow a full-length body. Practical sizing: at 0.5 MPa plan on about 2209 N of usable work (roughly 60% of rating), which corresponds to lifting about 188 kg vertically with a 2:1 margin. A fixed TPU bumper sits at both ends, and the through-rod resists rotation and side load while the rear rod can carry a sensor flag. Note the family is discontinued - the current-production drop-in is the ACED100X125, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED100X125SB (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 ACPD100X125SB Is Used
Press fixture clamping
The 3681.6 N rod-side force in both directions clamps and unclamps heavy automotive stamping dies with identical pressure, and the 125 mm stroke clears die loading in tight press beds.
Gantry lift-and-lower
A packaging line gantry uses the through-rod to lift about 188 kg of filled carton trays vertically with a 2:1 margin, the symmetric rod mount keeping the carriage level without extra guides.
Conveyor diverter pusher
On a bottling conveyor, the double rod resists side load as the pusher kicks cases off the line, while CMSE switches on the fitted magnet confirm extend and retract for the PLC.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD100X125SB with the ACED100X125SB
At 3681.6 N per direction (0.5 MPa) this 100 mm bore suits heavy clamping and lifting where equal force both ways matters; step down to the 80 mm bore (2356.2 N) for lighter loads or accept that the next size up does not exist in this series. The 125 mm stroke sits well inside the 300 mm maximum standard stroke for this bore, so it is a catalogue item, not a made-to-order build. Remember that a plain double-rod cylinder drifts when air is lost - add a rod lock or pilot check if the load must stay put. FA/FB flanges, LB feet and clevis mounts bolt to the same face, and the magnet this -S model carries pairs with CMSE / DMSE switches. For new designs, order the ACED100X125 instead: same bore, stroke and force class, currently in production.
Replacement checklist
- ✓ Current-production ACE → ACED100X125SB
- ✓ 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 ACPD100X125SB FAQ
Yes - the double-rod design means both strokes use the rod-side area, so force is equal either way: 3681.6 N at 0.5 MPa and 5154.2 N at 0.7 MPa, with a maximum of 750.8 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed range 30-500 mm/s, and the 1/4" port matches the 100 mm bore.
The ACPD family is no longer in production. The current drop-in is the ACED100X125 (swap the P for an E), an ISO 21287 compact cylinder in the same bore, stroke and force class with a matching short body and mounting family. Because the ACP is DIN-standard, confirm the ISO 21287 mounting dimensions before swapping. The male rod thread, 125 mm stroke and optional -S magnet for CMSE / DMSE switches all carry over.
