This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED50X90B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED50X90B 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 ACPD50X90B
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD50X90B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø50mm bore and 90mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED50X90B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD50X90B
A double acting, double-rod compact cylinder, the ACPD50X90B pushes a 50 mm bore through a 90 mm stroke with a rod leaving both covers, so it delivers 881.2 N in each direction at 0.5 MPa (1233.7 N at 0.7 MPa) because both strokes work on the rod-side area. The through-rod resists rotation and side load, and the rear rod can carry a sensor flag or a second tool. Its hard-anodized aluminium body keeps the mounting length roughly 50% shorter than an ISO 15552 profile cylinder, which is why it slots into tight fixtures and guarding.
Practical sizing: treat about 530 N as the usable working force at 0.5 MPa, which corresponds to lifting roughly 54 kg vertically with a 2:1 margin - enough headroom for a 25 kg pallet clamp or die component. The male rod thread (B code) accepts standard rod accessories, and fixed TPU bumpers pad both ends. Note this model is discontinued: the current-production drop-in is the ISO 21287 ACED50X90, so confirm mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED50X90B (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 ACPD50X90B Is Used
Press-side die clamping
The 881.2 N symmetric force clamps a stamping die shoe from both sides of the bolster, with the 90 mm stroke clearing die changes on a 60-ton press.
Bidirectional pusher on packaging lines
Equal force both ways lets one cylinder divert cartons left or right on a conveyor transfer, with the rear rod carrying a flag for position sensing.
Gantry lift-and-lower stage
The through-rod guides a small fixture plate vertically in a CNC tending gantry, lifting about 54 kg with a 2:1 margin at 0.5 MPa.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD50X90B with the ACED50X90B
At 881.2 N per side at 0.5 MPa, the 50 mm bore sits between the 40 mm (571.8 N) and 63 mm (1458.1 N) options - step down for lighter clamping, up when the load needs more margin. The 90 mm stroke is well inside the 250 mm standard limit for this bore. A plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check valve if the load must stay put. Mounting brackets bolt to the ISO 21287 face, and the optional -S magnet enables CMSE / DMSE switches. This unit is discontinued; order ACED50X90 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACED50X90B
- ✓ 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 ACPD50X90B FAQ
Yes - the double-rod design means both strokes use the rod-side area, so force is equal either way: 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 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, and the 16 mm rod ends in a male thread (B code).
Order the ACED50X90, the current-production ISO 21287 successor made by swapping the P for an E. It matches the same 50 mm bore, 90 mm stroke and force class with a short compact body and a compatible mounting family (FA/FB flange, LB foot, CA/CB clevis). Because the ACP is DIN-standard, confirm the ISO 21287 mounting dimensions against your fixture before the swap.
