This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED16X20B, 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 ACPD16X20B
The AirTAC ACPD Double Rod Compact Cylinder ACPD16X20B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø16mm bore and 20mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED16X20B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD16X20B
Double acting and double rod, the ACPD16X20B pushes a rod out of BOTH covers, so its 16 mm bore delivers the same 75.4 N in each direction at 0.5 MPa (105.6 N at 0.7 MPa) because both strokes work on the rod-side area. The 20 mm stroke keeps the body short, and the through-rod resists rotation and light side load while the rear rod can carry a sensor flag. This model is discontinued; the current-production direct is the ACED16X20, so confirm ISO 21287 mounting dimensions before swapping.
The hard-anodized aluminium body with an S45C hard-chrome rod saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight pick-and-place heads and small jigs. Run it on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s. Fixed TPU bumpers sit at both ends, and the male rod thread (B code) takes standard rod knuckles.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED16X20B (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 ACPD16X20B Is Used
Small-part ejection from a jig
The symmetric 75.4 N push and pull ejects a machined bushing from a tight fixture pocket where a full-length cylinder cannot fit.
Reciprocating test-slide drive
Equal force both ways drives a 20 mm-stroke inspection slide back and forth on an electronics test bench at 30-500 mm/s.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD16X20B with the ACED16X20B
At 75.4 N per direction, this 16 mm bore suits light clamping and transfer; step down to ACPD12 (42.4 N) for tiny fixtures or up to ACPD20 (117.8 N) when the part weight grows. The 20 mm stroke is well inside the 75 mm standard maximum for bore 16. The B code gives a male rod thread with a PT port thread. If you need position feedback, order the -S variant to enable CMSE / DMSE switches - this plain code has no magnet. For held loads, add a rod lock or pilot check, since the piston drifts when air is lost. Replace with ACED16X20 for new builds.
Replacement checklist
- ✓ Current-production ACE → ACED16X20B
- ✓ 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 ACPD16X20B FAQ
Because a rod exits both covers, force is equal in both directions: 75.4 N at 0.5 MPa and 105.6 N at 0.7 MPa, with a maximum of 15.4 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, port M5x0.8, rod 8 mm with a male thread (B code).
The short ISO 21287-class body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with FA/FB flange or LB foot mounting. Sensors need the optional -S magnet code (CMSE / DMSE switches); this plain model has no magnet. The ACPD16X20B is discontinued - the ACED16X20 is the current direct, so confirm ISO 21287 mounting dimensions first.
