This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED16X50S, the same code under the new prefix. 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 ACPD16X50S
The AirTAC ACPD Double Rod Compact Cylinder ACPD16X50S is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø16mm bore and 50mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED16X50S (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD16X50S
Double acting with a rod leaving both covers, the ACPD16X50S pushes and pulls with identical force because both strokes work on the rod-side area: 75.4 N at 0.5 MPa and 105.6 N at 0.7 MPa in either direction. The 16 mm bore drives an 8 mm through-rod at 30-500 mm/s on 0.15-1.0 MPa (22-145 psi) filtered air, with a fixed TPU bumper at each end. This unit carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke sensing.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into slim pick-and-place heads and compact test rigs. Note the ACPD line is discontinued: the current-production direct is the ACED16X50, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED16X50S (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 (Ø16mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 75 N |
| 0.7 MPa | 106 N |
| Max (@1.0 MPa) | 15 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 ACPD16X50S Is Used
Small-parts ejection from plastic molds
The symmetric 75.4 N push and pull at 0.5 MPa kicks finished caps or bushings off a mold table and retracts with equal force, and the 50 mm stroke clears the part in one move.
Position-flagged gantry slides
The rear rod carries a flag past CMSE or DMSE switches (enabled by the fitted -S magnet) on an electronics assembly slide, giving end-of-stroke confirmation in a 50 mm envelope.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD16X50S with the ACED16X50S
At 75.4 N per side at 0.5 MPa, the 16 mm bore suits light clamping and part transfer up to a few kilograms; step down to the 12 mm bore (42.4 N) for tiny fixtures or up to the 20 mm bore (117.8 N) when you need more margin. The 50 mm stroke sits inside the 75 mm standard limit for this bore, so no made-to-order build is required. The through-rod resists rotation and side load and the rear rod can carry a sensor flag, and FA/FB flange or LB foot mounts bolt to the standard face. Remember a plain through-rod cylinder drifts when air is lost, so add a rod lock or pilot check for a held load. Order the ACED16X50 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACED16X50S
- ✓ 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 ACPD16X50S FAQ
Because a rod exits both covers, force is equal both ways: 75.4 N at 0.5 MPa and 105.6 N at 0.7 MPa on each stroke, with a maximum of 15.4 kgf at 1.0 MPa. The 16 mm bore uses an 8 mm rod, an M5x0.8 port and an M4x0.7 female rod thread, and the standard stroke limit for this bore is 75 mm, so the 50 mm stroke is a catalog size.
The hard-anodized aluminium body follows the short ISO 21287-class footprint and saves about 50% of the mounting length of an ISO 15552 profile cylinder, with FA/FB flange and LB foot options and a fixed TPU bumper at each end. The ACPD family is discontinued; the current-production direct is the ACED16X50 (same bore, stroke and force class), so verify the ISO 21287 mounting dimensions before you swap.
