This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE100X50B, 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 ACP Compact Cylinder ACP100X50B
The AirTAC ACP Compact Cylinder ACP100X50B is a double acting DIN-standard tight/compact air cylinder with a Ø100mm bore and 50mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE100X50B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP100X50B
The ACP100X50B is a double acting compact cylinder in the discontinued AirTAC ACP DIN-standard series, with a 100 mm bore and a short 50 mm stroke. Its hard-anodized aluminium body is roughly 50% shorter in mounting length than an ISO 15552 profile cylinder, so it slots into heavy presses, clamping fixtures and gantry heads where a full-length body simply will not fit. The male rod thread (B code) on the 25 mm S45C hard-chrome rod accepts standard rod knuckles directly.
At 0.5 MPa this bore pushes 3927 N and pulls 3681.6 N; at 0.7 MPa it reaches 5497.8 N. Air supply is 0.15-1.0 MPa (22-145 psi), speed runs 30-500 mm/s, and fixed TPU bumpers sit at both ends. This model is discontinued: the current-production direct is the ACE100X50, so confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE100X50B (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 (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | 5154 N |
| Max (@1.0 MPa) | 801 kgf | |
The ACE100X50B produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac ACP Compact Cylinder ACP100X50B Is Used
Stamping press die clamp
The 3927 N push at 0.5 MPa clamps stamping die halves in a 50 mm stroke, and the short body fits inside the press bolster where longer cylinders cannot reach.
Pallet gate actuator
A warehouse pallet-dispensing gate swings on this bore's force class; the male rod thread takes a clevis knuckle without an adapter.
Bottle-capper hold-down
On a beverage line, the 100 mm bore holds capper heads down against spring reaction, with the 1/4" port feeding high flow for the 30-500 mm/s cycle.
Replacing the Airtac ACP Compact Cylinder ACP100X50B with the ACE100X50B
At 100 mm bore this is the top of the ACP range: 3927 N push at 0.5 MPa versus 2513 N for the 80 mm bore below it. If your load needs under 2500 N, step down to ACP80; if you need more force at the same footprint, the ACE family carries the same class forward. Note that a plain ACP100X50B does not hold position when air is lost - the piston drifts - so add a rod lock or pilot check valve for held loads. This unit has no magnet fitted; order the -S code if you want CMSE or DMSE switches. Mount with FA/FB flange, LB foot, CA/CB clevis or SDB pivot brackets on the ISO 21287 face. Replacement: ACE100X50.
Replacement checklist
- ✓ Current-production ACE → ACE100X50B
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ACP Compact Cylinder ACP100X50B FAQ
Push is 3927 N and pull 3681.6 N at 0.5 MPa; at 0.7 MPa push rises to 5497.8 N, with a theoretical maximum of 800.9 kgf at 1.0 MPa. It is double acting, 100 mm bore, 50 mm stroke, 25 mm rod with male thread, 1/4" PT port, operating on 0.15-1.0 MPa (22-145 psi) filtered air at 30-500 mm/s. The model is discontinued; the ACE100X50 is the current replacement.
The hard-anodized aluminium body is a short ISO 21287-class build, saving about 50% of the mounting length of an ISO 15552 profile cylinder. Fixed TPU bumpers at both ends decelerate the piston at end of travel. FA/FB flange, LB foot and CA/CB clevis mounts bolt to the standard face, and the optional -S magnet enables CMSE / DMSE switches. Confirm ISO 21287 dimensions when moving to the ACE100X50.
