This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED80X50B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED80X50B 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 ACPD80X50B
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD80X50B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø80mm bore and 50mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED80X50B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD80X50B
A double acting compact cylinder with a rod leaving both covers, the ACPD80X50B pushes and pulls with identical force: 2356.2 N at 0.5 MPa and 3298.7 N at 0.7 MPa in either direction, because both strokes work on the rod-side area of the 80 mm bore. The through-rod resists rotation and side load, gives a symmetric mount, and lets the rear rod carry a sensor flag. A fixed TPU bumper sits at each end, and speed runs 30-500 mm/s across 0.15-1.0 MPa (22-145 psi) of clean, 40 um filtered air.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight presses, clamps and gantries. At 0.5 MPa, plan on about 1414 N of usable work (roughly 60% of rating), which is about 120 kg of vertical lift with a 2:1 margin. Note this model is discontinued: the current-production drop-in is the ACED80X50, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED80X50B (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 (Ø80mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 2356 N |
| 0.7 MPa | 3299 N |
| Max (@1.0 MPa) | 481 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 ACPD80X50B Is Used
Bench press clamping
The 2356.2 N rod-side force at 0.5 MPa suits a small stamping or riveting fixture on a 50 mm stroke, with equal return force so no spring is needed.
Reciprocating guide carriage
A rod on each cover lets the through-rod drive a sliding carriage in a packaging machine symmetrically, resisting rotation and side load at 30-500 mm/s.
Pallet-stacker lift assist
With about 120 kg of vertical lift capacity at a 2:1 margin, the 80 mm bore raises a loaded pallet nose or counterweight arm in a compact warehouse mechanism.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD80X50B with the ACED80X50B
For a 50 mm stroke needing equal force both ways, the 80 mm bore delivers 2356.2 N at 0.5 MPa; step down to a 63 mm bore (1458.1 N) for lighter clamping or up to a 100 mm bore (3681.6 N) for heavy tooling. Remember a plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check for held loads. The B code gives a male 20 mm rod thread and PT ports; FA/FB flange or LB foot mounting bolts to the same face. This unit has no magnet, so order the -S version if you need CMSE / DMSE switches. Since ACPD is discontinued, specify the ACED80X50 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACED80X50B
- ✓ 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 ACPD80X50B FAQ
No. Because a rod exits both covers, both strokes use the rod-side area of the 80 mm bore, so force is equal in each direction: 2356.2 N at 0.5 MPa and 3298.7 N at 0.7 MPa. At the full 1.0 MPa rating the cylinder reaches about 480.5 kgf. Operating range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure.
The hard-anodized aluminium body is an ISO 21287-class short build, saving about 50% of the mounting length of an ISO 15552 profile cylinder, with FA/FB flange or LB foot options and a fixed TPU bumper at each end that simply decelerates the piston. The ACPD80X50B is discontinued; the current drop-in is the ACED80X50 (same bore, stroke and force class), so verify ISO 21287 mounting dimensions before ordering.
