This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED50X80SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED50X80SB 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 ACPD50X80SB
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD50X80SB is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø50mm bore and 80mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED50X80SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD50X80SB
A double acting compact cylinder with a rod through both covers, the ACPD50X80SB delivers 881.2 N at 0.5 MPa and 1233.7 N at 0.7 MPa in either direction, since both strokes work on the rod-side area. The 16 mm through-rod resists rotation and side load, gives a symmetric mount, and the rear rod can carry a sensor flag. Fixed TPU bumpers sit at both ends, and speed spans 30-500 mm/s.
The hard-anodized aluminium body follows the short ISO 21287 format, saving about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight presses and gantries. At 0.5 MPa the usable push force is roughly 530 N after a 40% reserve, which lifts about 45 kg vertically with a 2:1 margin. This model is discontinued; the current-production drop-in is ACED50X80, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED50X80SB (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 ACPD50X80SB Is Used
Bench-top crimping press
The 881.2 N equal force in both directions suits a small harness-crimping fixture where the through-rod lets the tool clamp on the front stroke and eject on the return.
Bottling line pusher
A 16 mm through-rod on a beverage conveyor guide rail resists side load while the rear rod carries a DMSE switch flag for position feedback.
Gantry pick-and-place
The short ISO 21287 body fits a low gantry crossbeam, and the symmetric double-rod mount keeps a 45 kg vertical lift stable with a 2:1 margin at 0.5 MPa.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD50X80SB with the ACED50X80SB
For a 50 mm job needing 881.2 N both ways, this size sits between the 40 mm bore (571.8 N at 0.5 MPa) and the 63 mm bore (1458.1 N at 0.5 MPa). The 80 mm stroke is within the 250 mm standard range for bore 50. Remember the piston 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 this model carries accepts CMSE / DMSE switches. Order ACED50X80 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACED50X80SB
- ✓ 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 ACPD50X80SB FAQ
Because a rod exits both covers, force is equal in both directions: 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 pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), and speed 30-500 mm/s.
No - the ACPD family is discontinued. The current-production drop-in is ACED50X80 (swap the P for an E), which matches the same bore, stroke and force class in the ISO 21287 format. Confirm the ISO 21287 mounting dimensions against your fixture before swapping, since the ACP is DIN-standard. The fixed TPU bumpers at both ends simply decelerate the piston at each end of travel.
