This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED50X30B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED50X30B 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 ACPD50X30B
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD50X30B 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 ACED50X30B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD50X30B
A double acting compact cylinder with a rod exiting both covers, the ACPD50X30B delivers 881.2 N at 0.5 MPa in each direction because both strokes work on the rod-side area of the 50 mm bore. The 16 mm through-rod resists rotation and side load, gives a symmetric mount, and the rear rod can carry a sensor flag. Its short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and gantries.
The hard-anodized aluminium body carries aluminium covers with a fixed TPU bumper at each end, and the S45C hard-chrome rod runs at 30-500 mm/s on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi). Note that this model is discontinued: the current-production drop-in is the ACED50X30, same bore, stroke and force class, so confirm ISO 21287 mounting dimensions before swapping. For planning, treat roughly 0.6 of the 881.2 N rating as usable work, which is about 54 kg of vertical lift with a 2:1 margin.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED50X30B (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 ACPD50X30B Is Used
Two-sided press fixture
The through-rod lets a machining cell clamp a gearbox housing from both covers with one cylinder, applying 881.2 N each way at 0.5 MPa in a fixture too short for a full-length profile cylinder.
Bidirectional pusher on a packaging line
Equal force in both strokes makes the 50 mm bore ideal for a carton divertor that pushes trays left or right off a conveyor, with the rear rod carrying a position flag when the -S magnet is ordered.
Lift-assist stamping nest
With about 54 kg of practical vertical lift at a 2:1 margin, the cylinder raises a small stamping die nest in a press shop, the 30 mm stroke matching a shallow die-change shuttle.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD50X30B with the ACED50X30B
At 881.2 N per direction the 50 mm bore sits between the 40 mm (571.8 N) and 63 mm (1458.1 N) choices at 0.5 MPa, so step up to 63 mm if the load needs more headroom. The 30 mm stroke is well inside the 250 mm maximum standard stroke for this bore. This B-code version has a male rod thread on a PT port thread; the through-rod suits symmetric fixtures, but the piston will drift if air is lost, so add a rod lock or pilot check where a load must be held. Mount with FA/FB flange or LB foot brackets, and remember the magnet is the optional -S code - without it no CMSE or DMSE switch can be fitted. Order the ACED50X30 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACED50X30B
- ✓ 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 ACPD50X30B FAQ
Yes - the double-rod design means both strokes use the rod-side area, so output is equal each way: 881.2 N at 0.5 MPa and 1233.7 N at 0.7 MPa, with a maximum of 179.7 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) and speed is 30-500 mm/s.
The ACPD50X30B is no longer in production; the current drop-in is the ACED50X30, which matches the same 50 mm bore, 30 mm stroke and force class - confirm the ISO 21287 mounting dimensions before swapping. For position sensing, order the -S magnet code so CMSE or DMSE switches can be mounted; without -S there is no magnet.
