This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED63X55B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED63X55B 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 ACPD63X55B
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD63X55B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø63mm bore and 55mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED63X55B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD63X55B
This is a double acting compact cylinder with a double rod: a 16 mm piston rod exits both covers of the hard-anodized aluminium body, so the 63 mm bore delivers the same 1458.1 N at 0.5 MPa (2041.3 N at 0.7 MPa) on every stroke, since both sides work on the rod-side area. The male rod thread (B code) on each end bolts straight to tooling, and a fixed TPU bumper sits at both covers. Speed range is 30-500 mm/s over 0.15-1.0 MPa (22-145 psi) of clean, 40 um filtered air.
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why this size suits tight gantries and fixture plates. Because the through-rod resists rotation and side load, the rear rod can carry a sensor flag while the front rod does the work; at 0.5 MPa plan on roughly 875 N of usable push, which lifts about 89 kg vertically with a 2:1 margin. Note this model is discontinued - the current-production drop-in is ACED63X55, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED63X55B (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 (Ø63mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 1458 N |
| 0.7 MPa | 2041 N |
| Max (@1.0 MPa) | 297 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 ACPD63X55B Is Used
Two-sided press fixture
The male-threaded rods on both ends let a welding fixture push a clamp from the front while the rear rod drives a position flag, with 1458.1 N available either way at 0.5 MPa.
Reciprocating transfer slide
A 55 mm shuttle between two pallet stops on an electronics assembly line uses the equal 2041.3 N at 0.7 MPa in both directions, so no derating is needed on the return stroke.
Vertical ejector station
Ejecting filled cartons downward from a packaging chute: the through-rod resists the side load of an off-center part, and the 89 kg vertical-lift equivalent covers typical carton stacks.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD63X55B with the ACED63X55B
Size both ways: if 1458.1 N at 0.5 MPa is more than the job needs, the ACPD50 at the same stroke gives 881.2 N; if you need more, step up to the ACPD80 for 2356.2 N. Remember the force is identical in both directions here - there is no larger push than pull on a double-rod cylinder. The 55 mm stroke sits well inside the 250 mm maximum standard stroke for this bore, so it is a catalogue item, not a made-to-order build. A plain double-rod cylinder will not hold a load when air is lost - add a rod lock or pilot check valve if the position must be kept. Mount with FA/FB flange or LB foot brackets on the standard face, and if you need end-of-stroke detection, order the -S code so CMSE or DMSE switches can be fitted - without -S there is no magnet. This model is discontinued; the ACED63X55 is the current replacement in the same bore, stroke and force class.
Replacement checklist
- ✓ Current-production ACE → ACED63X55B
- ✓ 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 ACPD63X55B FAQ
Yes - this is a double-rod cylinder, so a 16 mm rod exits both covers and every stroke uses the rod-side area. At 0.5 MPa you get 1458.1 N, at 0.7 MPa you get 2041.3 N, both ways, and the maximum force at 1.0 MPa is 297.4 kgf. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, speed 30-500 mm/s, air filtered to 40 um.
Order the ACED63X55, the current-production ISO 21287 replacement (swap the P for an E). It matches the same 63 mm bore, 55 mm stroke and force class, with the same fixed TPU bumper at both ends and FA/FB flange or LB foot mounting. Because the ACP was built to a DIN-standard face, confirm the ISO 21287 mounting dimensions against your fixture before swapping. If you need position switches, the -S magnet code enables CMSE / DMSE sensors.
