This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED16X50SB, 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 ACPD16X50SB
The AirTAC ACPD Double Rod Compact Cylinder ACPD16X50SB 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 ACED16X50SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD16X50SB
A double acting, double-rod compact cylinder in the DIN-standard ACP family, the ACPD16X50SB pushes a 16 mm bore through a 50 mm stroke with a rod leaving both covers. Because both strokes work on the rod-side area, output is identical either way: 75.4 N at 0.5 MPa and 105.6 N at 0.7 MPa. The B code gives a male rod thread, the S code fits the optional -S magnet so CMSE / DMSE switches can read position, and a fixed TPU bumper sits at each end. Running pressure is 0.15-1.0 MPa (22-145 psi) with speeds of 30-500 mm/s.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits slim pick-and-place heads and tight fixture pockets. The through-rod resists rotation and side load and gives a symmetric mount, and the rear rod can carry a sensor flag. Note this model is discontinued: the current direct is the ACED16X50, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED16X50SB (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 ACPD16X50SB Is Used
Small-part ejection from plastic molds
The 75.4 N symmetric output at 0.5 MPa is enough to kick finished caps or bushings off a mold table, and the 50 mm stroke clears the part without a long body.
Position-flagged test fixtures
With the -S magnet fitted, CMSE or DMSE switches on either cover confirm clamp-open and clamp-close states, while the rear rod can drive an independent flag.
Bidirectional pusher on packaging lines
Equal force in both directions lets one cylinder divert cartons left or right on a conveyor, with the through-rod keeping the pusher plate square under side load.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD16X50SB with the ACED16X50SB
At 75.4 N per side at 0.5 MPa this bore 16 unit covers light clamping and small part transfer; step down to the ACPD12 (42.4 N) for lighter jigs or up to the ACPD20 (117.8 N) if the load grows. The 50 mm stroke sits inside the 75 mm standard limit for bore 16, so no made-to-order build is needed. Choose LB foot or FA/FB flange mounting to match the fixture, and remember the -S magnet is what enables CMSE / DMSE switch feedback. Since a plain double-rod cylinder drifts when air is lost, add a rod lock or pilot check for held loads. For new projects, order the ACED16X50 instead - same bore, stroke and force class.
Replacement checklist
- ✓ Current-production ACE → ACED16X50SB
- ✓ 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 ACPD16X50SB FAQ
Yes. As a double-rod cylinder both strokes use the rod-side area, so force is equal either way: 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 pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the 8 mm rod carries a male thread (B code).
Order the ACED16X50, the current-production ISO 21287 successor made by swapping the P for an E. It matches the same 16 mm bore, 50 mm stroke and force class, and accepts the same FA/FB flange and LB foot mounting family. Because the ACP is DIN-standard, confirm the ISO 21287 mounting dimensions against your fixture before swapping.
