This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED50X50SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED50X50SB 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 ACPD50X50SB
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD50X50SB is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø50mm bore and 50mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED50X50SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD50X50SB
Double acting with a rod leaving both covers, the ACPD50X50SB pushes and pulls with identical output: 881.2 N at 0.5 MPa and 1233.7 N at 0.7 MPa in either direction, because both strokes work on the rod-side area of the 50 mm bore. The 16 mm through-rod resists rotation and side load, gives a symmetric mount, and the rear rod can carry a sensor flag. This unit carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches mount directly on the body. A fixed TPU bumper sits at each end and the rod ends in a male thread (B code).
The hard-anodized aluminium body follows the ISO 21287 short format, cutting roughly 50% of the mounting length compared with an ISO 15552 profile cylinder, which suits tight jigs and gantries. Practical sizing: plan on about 529 N of usable force at 0.5 MPa, which lifts roughly 45 kg vertically with a 2:1 margin. Speed range is 30-500 mm/s over 0.15-1.0 MPa (22-145 psi). Note that this model is discontinued; the current-production replacement is the ACED50X50, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED50X50SB (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 ACPD50X50SB Is Used
Reciprocating transfer slide
The through-rod drives a slide on a packaging line where equal push and pull force (881.2 N at 0.5 MPa) keeps return stroke timing identical to the advance stroke at 30-500 mm/s.
Position-flagged press station
With the -S magnet this model carries, CMSE or DMSE switches confirm end positions on a small electronics assembly press, while the rear rod carries a secondary flag for mid-stroke detection.
Symmetric clamp fixture
A machining fixture clamps from both sides using the two rod ends of the male-thread B version, applying about 529 N of usable clamping force per side at 0.5 MPa.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD50X50SB with the ACED50X50SB
At 50 mm bore you sit mid-range: the 40 mm ACPD40 gives 571.8 N at 0.5 MPa while the 63 mm ACPD63 reaches 1458.1 N, so step up if your part weight approaches the 45 kg vertical-lift figure with margin. Stroke 50 mm is well inside the 250 mm maximum standard stroke for this bore. If the load must stay put when air is lost, add a rod lock or pilot check - the through-rod alone will drift. Match FA/FB flange or LB foot brackets to the ISO 21287 face, and order the -S code if you need switch positions. Since ACPD is discontinued, spec the ACED50X50 as the drop-in successor and verify mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACED50X50SB
- ✓ 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 ACPD50X50SB 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 of the 50 mm bore, so there is no push-versus-pull difference. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the fixed TPU bumper decelerates at each end.
The hard-anodized aluminium body follows the ISO 21287 short format, saving about 50% of the mounting length of an ISO 15552 profile cylinder, with FA/FB flange and LB foot options plus a male rod thread on this B-coded unit. The ACPD family is discontinued; the current-production drop-in is the ACED50X50 (same bore, stroke and force class). Confirm the ISO 21287 mounting dimensions before swapping, since the ACP was built to a DIN-standard footprint.
