This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED50X30S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED50X30S 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 ACPD50X30S
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD50X30S is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø50mm bore and 30mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED50X30S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD50X30S
A double acting compact cylinder with a rod through both covers, the ACPD50X30S delivers 881.2 N in either direction at 0.5 MPa because both strokes work on the rod-side area. The 50 mm bore carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke detection. This model is discontinued; the current-production drop-in is the ACED50X30.
The hard-anodized aluminium body follows the ISO 21287 short format, cutting roughly 50% of the mounting length of an ISO 15552 profile cylinder, which suits tight jigs and guard-mounted tooling. The 16 mm through-rod resists rotation and side load and gives a symmetric mount, while fixed TPU bumpers at each end absorb the stroke ends. Speed range is 30-500 mm/s over 0.15-1.0 MPa (22-145 psi). In practice, plan on about 529 N (roughly 54 kg) of usable push at 0.5 MPa, enough to lift about 45 kg vertically with a 2:1 margin.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED50X30S (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 (Ø50mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 881 N |
| 0.7 MPa | 1234 N |
| Max (@1.0 MPa) | 180 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 ACPD50X30S Is Used
Press-side part ejection
The back-end rod on a packaging line ejector pushes finished cartons off a forming die with the same 881.2 N as the working stroke, so one cylinder does both jobs.
Reciprocating slide drive
A 30 mm stroke through-rod drives a bidirectional transfer slide on an electronics assembly cell, where equal force both ways keeps cycle motion symmetric at 30-500 mm/s.
Gated fixture with position feedback
With the -S magnet fitted, CMSE or DMSE switches confirm gate closure on a machine guard interlock, and the short ISO 21287 body fits inside the guard channel.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD50X30S with the ACED50X30S
At 881.2 N per side, the 50 mm bore sits between the 40 mm (571.8 N) and 63 mm (1458.1 N) options at 0.5 MPa. Step down to 40 mm for lighter clamping, or up to 63 mm when the load needs more than double the force. The 30 mm stroke is well inside the 250 mm maximum standard stroke for this bore, so no made-to-order build is required. 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 flange and LB foot mountings bolt to the ISO 21287 face, and the -S magnet in this unit works with CMSE / DMSE switches. For new projects, order the ACED50X30 and confirm the ISO 21287 mounting dimensions before swapping.
Replacement checklist
- ✓ Current-production ACE → ACED50X30S
- ✓ 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 ACPD50X30S FAQ
Yes - as a double-rod cylinder both strokes use the rod-side area, so force is equal either way: 881.2 N at 0.5 MPa and 1233.7 N at 0.7 MPa, with a maximum of about 179.7 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) and speed is 30-500 mm/s.
Order the ACED50X30, the current ISO 21287 successor made by swapping the P for an E. It matches the same 50 mm bore, 30 mm stroke and force class, and accepts FA/FB flange and LB foot mountings. Because the ACP is DIN-standard, confirm the ISO 21287 mounting dimensions before swapping.
