This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED50X100B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED50X100B 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 ACPD50X100B
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD50X100B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø50mm bore and 100mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED50X100B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD50X100B
A double acting compact cylinder with a rod through both covers, the ACPD50X100B delivers 881.2 N in each direction at 0.5 MPa because both strokes work on the rod-side area. The 16 mm through-rod resists rotation and side load, carries a symmetric mount, and leaves the rear rod free for a sensor flag. Its 100 mm stroke sits well inside the 250 mm maximum standard stroke for a 50 mm bore.
The hard-anodized aluminium body is an ISO 21287 short build that saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight packaging frames and gantries. A fixed TPU bumper pads both ends, and speed runs 30-500 mm/s over 0.15-1.0 MPa (22-145 psi). This model is discontinued; the current drop-in is ACED50X100. Note the male rod thread (B code) and PT ports, and confirm ISO 21287 mounting dimensions before swapping. As a rule of thumb, plan on roughly 529 N (about 54 kg of push) of real work at 0.5 MPa, or lift about 45 kg vertically with a 2:1 margin.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED50X100B (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 ACPD50X100B Is Used
Reciprocating conveyor pusher
The equal 881.2 N output in both directions suits a packaging-line pusher that must index cartons forward and retract under the same force at 30-500 mm/s.
Clamping fixture with rear flag
On a machining jig, the 16 mm through-rod clamps a workpiece at the front while the rear rod carries a switch flag for clamp-confirmation logic.
Vertical lift-and-lower slide
A gantry z-axis lowering about 45 kg per stroke uses the symmetric through-rod mount to keep the tool plate square without an anti-rotation bracket.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD50X100B with the ACED50X100B
At 881.2 N per side, the 50 mm bore sits between the 40 mm (571.8 N) and 63 mm (1458.1 N) double-rod sizes at 0.5 MPa; step up if your tooling mass grows, step down for lighter pick-and-place. A plain through-rod cylinder drifts when air is lost, so add a rod lock or pilot check for held loads. FA/FB flange and LB foot mountings bolt to the ISO 21287 face. No magnet is fitted on this code, so CMSE or DMSE switches cannot be used; order the -S variant if you need position sensing. Replace it with ACED50X100 and verify the mounting footprint first.
Replacement checklist
- ✓ Current-production ACE → ACED50X100B
- ✓ 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 ACPD50X100B FAQ
Yes. Because a rod exits both covers, both strokes use the rod-side area: 881.2 N at 0.5 MPa and 1233.7 N at 0.7 MPa, equal in each direction, with a maximum of 179.7 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, air filtered to 40 um.
This model is discontinued; the current-production drop-in is ACED50X100, the ISO 21287 successor in the same bore, stroke and force class - confirm the mounting dimensions before swapping. This code has no magnet, so no CMSE or DMSE switch can be fitted; the optional -S version carries the magnet for position sensing. The fixed TPU bumpers only decelerate the piston at each end.
