This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED80X50SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED80X50SB 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 ACPD80X50SB
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD80X50SB 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 ACED80X50SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD80X50SB
This is a double acting, double-rod compact cylinder in the discontinued AirTAC ACPD series, built to the DIN-standard short-body format with a hard-anodized aluminium body and an S45C hard-chrome piston rod. A 20 mm rod exits BOTH covers, so the 80 mm bore delivers an identical 2356.2 N at 0.5 MPa (3298.7 N at 0.7 MPa) in each direction - push and pull are the same because both strokes work on the rod-side area. The male rod thread (B code) bolts straight to I/Y knuckles, and the fixed TPU bumper pads at both ends absorb end-of-travel shock.
Because the through-rod resists rotation and side load and gives a symmetric mount, the back-end rod is a natural carrier for a sensor flag - and this model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be fitted. The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight press fixtures and gantries. In practice, plan on roughly 1414 N of usable work at 0.5 MPa (about 0.6 of the rating), which corresponds to lifting around 72 kg vertically with a 2:1 margin. Note: this model is discontinued - the current-production drop-in is ACED80X50, so confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED80X50SB (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 ACPD80X50SB Is Used
Symmetric press fixture
The equal 2356.2 N output in both directions lets one 80 mm cylinder clamp a steel housing on the extend stroke and eject it on retract, with the male rod thread taking an I/Y knuckle directly.
Two-sided gantry actuator
A rod at each end of the 50 mm stroke drives a workpiece and a mirror-mounted sensor flag simultaneously, so CMSE switches on the -S magnet report position from either side.
Pallet-stacking pusher
At roughly 72 kg of vertical lift equivalent with a 2:1 margin, the through-rod guides a transfer plate on a warehouse stacker without rotating under side load.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD80X50SB with the ACED80X50SB
Size both ways before committing: the 63 mm bore gives 1458.1 N at 0.5 MPa if your load is lighter, while the 100 mm bore reaches 3681.6 N for heavier clamping. With 2356.2 N available in both directions, this 80 mm unit suits symmetric tooling where the same force is needed on extend and retract. 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 mounts bolt to the standard face, and the -S magnet on this model enables CMSE / DMSE switch positioning. This ACPD is discontinued; order ACED80X50 as the current replacement and verify the ISO 21287 mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACED80X50SB
- ✓ 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 ACPD80X50SB FAQ
Yes - the double-rod design means both strokes use the rod-side area, so force is equal both ways: 2356.2 N at 0.5 MPa and 3298.7 N at 0.7 MPa, with a maximum of 480.5 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the 1/4" port depends only on the 80 mm bore.
Order ACED80X50, the current-production ISO 21287 successor: swap the P for an E and you get the same 80 mm bore, 50 mm stroke and force class in a short-body aluminium cylinder. Confirm the ISO 21287 mounting dimensions against your fixture before swapping, since the ACP was built to the DIN-standard format, and re-check whether your switches need the optional -S magnet code.
