This model is discontinued

AirTAC has phased out the MAL series. The drop-in replacement is ACED50X160B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED50X160B 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 ACPD50X160B

The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD50X160B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø50mm bore and 160mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED50X160B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD50X160B

A double acting compact cylinder with a through piston rod, the ACPD50X160B pushes and pulls with identical force: 881.2 N at 0.5 MPa and 1233.7 N at 0.7 MPa in each direction, because both strokes work on the rod-side area of the 50 mm bore. The 16 mm rod exits both covers, so the back-end rod can carry a sensor flag or a second tool while resisting rotation and side load. A fixed TPU bumper sits at each end, and speed spans 30-500 mm/s.

The short ISO 21287-style body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight fixtures and sliding guards. In practice, plan on about 529 N of usable push at 0.5 MPa, which lifts roughly 45 kg vertically with a 2:1 margin. Note this model is discontinued: the current-production drop-in is the ACED50X160, so confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED50X160B (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)

PressureForce (both ways)
0.5 MPa881 N
0.7 MPa1234 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 ACPD50X160B Is Used

swap_horiz

Reciprocating conveyor pushers

The equal 881.2 N force in both directions gives the same return stroke power as the push, so a packaging-line pusher rejects cartons at full speed on the way back too.

settings

Synchronized press fixtures

A through rod on a drilling or riveting jig lets the rear rod carry a position flag while the front rod clamps, keeping both ends of the fixture symmetric and rotation-free.

precision_manufacturing

Compact gantry lift stations

With about 45 kg of vertical lift at a 2:1 margin, the 160 mm stroke raises small pallets or tooling plates inside a gantry frame too short for a full-length cylinder.

Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD50X160B with the ACED50X160B

At 881.2 N per direction, the 50 mm bore sits mid-range: step down to the 40 mm bore (571.8 N at 0.5 MPa) for lighter clamping, or up to the 63 mm bore (1458.1 N) when the load needs more margin. The 160 mm stroke is within the 250 mm standard limit for this bore, so no made-to-order build is required. If the machine must hold position when air is lost, add a rod lock or pilot check valve, since a plain through-rod cylinder drifts. This unit has the B male rod thread and no magnet; order the -S code if you later need CMSE or DMSE switch sensing. For new projects, specify the ACED50X160 instead.

Replacement checklist

  • ✓ Current-production ACE → ACED50X160B
  • ✓ 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 ACPD50X160B FAQ

Because it is a double-rod cylinder, force is identical in both directions: 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 pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), and speed 30-500 mm/s. The 50 mm bore takes a 1/8" port and the B code gives a male rod thread.

AirTAC no longer produces the ACPD family. The current drop-in is the ACED50X160, the ISO 21287 successor with the same 50 mm bore, 160 mm stroke and force class. Since the ACP was built to a DIN-standard footprint, verify the ISO 21287 mounting dimensions against your fixture before swapping. If you need position sensing, the ACED with the magnet option accepts CMSE or DMSE switches.
