This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED50X70S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED50X70S 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 ACPD50X70S
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD50X70S is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø50mm bore and 70mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED50X70S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD50X70S
A double acting compact cylinder with a through piston rod, the ACPD50X70S pushes 881.2 N and pulls 881.2 N at 0.5 MPa because both strokes work on the rod-side area. The 50 mm bore carries a 16 mm rod out of each cover, so the back-end rod can drive a sensor flag or a second tool while resisting rotation and side load. Its short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it fits tight jigs and guarding where a full-length body will not.
The S code means the optional -S magnet is fitted on this unit, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke signalling. A fixed TPU bumper sits at each end, the hard-anodized aluminium body pairs with an S45C hard-chrome rod, and speed runs 30-500 mm/s over 0.15-1.0 MPa (22-145 psi). Note the family is discontinued: the current-production drop-in is the ACED50X70, so confirm ISO 21287 mounting dimensions before swapping. For sizing, treat about 529 N (roughly 54 kgf) as the usable working force at 0.5 MPa, and expect about 45 kg of vertical lift with a 2:1 margin.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED50X70S (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 ACPD50X70S Is Used
Case clamp on a carton sealer
The through rod clamps a carton from both sides with equal 881.2 N force at 0.5 MPa, and the fitted -S magnet signals clamp-complete to the PLC via a DMSE switch.
Flip fixture for machined housings
A rod on each cover lets the 70 mm stroke rotate an aluminium housing 180 degrees in a CNC cell, with the symmetric mount resisting rotation without extra guides.
Pusher on a bottling line
At 30-500 mm/s the cylinder diverts bottles between lanes, and the fixed TPU bumpers at both ends take the end-of-stroke shock on every cycle.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD50X70S with the ACED50X70S
At 881.2 N per direction this bore 50 unit sits between the 40 mm frame (571.8 N at 0.5 MPa) and the 63 mm frame (1458.1 N), so step up only if your fixture mass exceeds about 529 N of real demand. The 70 mm stroke is well inside the 250 mm standard range for bore 50, so no made-to-order build is needed. FA/FB flange or LB foot mounts bolt to the standard face, and the female M10x1.5 rod thread accepts I/Y knuckles directly. Because a plain through-rod cylinder drifts when air is lost, add a rod lock or pilot check if the load must stay put. Order the ACED50X70 as the current replacement and verify its ISO 21287 footprint against your fixture.
Replacement checklist
- ✓ Current-production ACE → ACED50X70S
- ✓ 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 ACPD50X70S FAQ
Because a rod exits both covers, force is equal both ways: 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. Both strokes use the rod-side area, so there is no push-versus-pull difference. Plan on roughly 529 N of usable working force at 0.5 MPa, about 45 kg of vertical lift with a 2:1 margin.
The S in the model code means the optional -S magnet is fitted, so CMSE or DMSE reed and solid-state switches mount directly for position feedback; units ordered without -S carry no magnet. The ACPD family is discontinued, and the current-production drop-in is the ACED50X70 in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before you swap. The body is a hard-anodized aluminium compact build with a fixed TPU bumper at each end, not an adjustable device.
