This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE80X120SB, 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 ACP80X120SB
The AirTAC ACP Compact Cylinder ACP80X120SB is a double acting DIN-standard tight/compact air cylinder with a Ø80mm bore and 120mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE80X120SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP80X120SB
A double acting compact cylinder in the DIN-standard ACP series, the ACP80X120SB pairs an 80 mm bore with a 120 mm stroke and a 20 mm male-threaded rod (the B code). At 0.5 MPa it pushes 2513.3 N and pulls 2356.2 N, rising to 3518.6 N on extension at 0.7 MPa - enough for heavy clamping and press-fit work. The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into dense machine frames where a full-length body will not fit.
This model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke signalling. Because the body is hard-anodized aluminium with an S45C hard-chrome rod and fixed TPU bumpers at both ends, it runs at 30-500 mm/s across 0.15-1.0 MPa (22-145 psi). Note that the ACP line is discontinued - the current-production direct is the ACE80X120, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE80X120SB (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 (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2356 N |
| 0.7 MPa | 3519 N | 3299 N |
| Max (@1.0 MPa) | 513 kgf | |
The ACE80X120SB 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 ACP80X120SB Is Used
Press-fit and staking station
3518.6 N of push at 0.7 MPa gives the 80 mm bore enough force to press bushings into aluminium housings on an automotive sub-assembly line, with the 120 mm stroke clearing part loading.
Heavy fixture clamping
On a CNC machining fixture for steel castings, the 2513.3 N holding push at 0.5 MPa secures the workpiece while the male rod thread drives a swing clamp arm.
Pallet gate actuation
The short body fits inside a warehouse pallet-dispenser frame, pushing a 120 kg gate section vertically with margin, while DMSE switches on the -S magnet confirm gate position.
Replacing the Airtac ACP Compact Cylinder ACP80X120SB with the ACE80X120SB
At 2513.3 N push and 2356.2 N pull at 0.5 MPa, the 80 mm bore suits heavy fixtures; step down to the 63 mm bore (1558.6 N push) for lighter loads or up to the 100 mm bore (3927.0 N push) when force headroom matters. The 120 mm stroke sits well inside the 300 mm maximum standard stroke for this bore. The male rod thread (B) accepts I/Y knuckles directly, and FA/FB flange, LB foot or CA/CB clevis mounts bolt to the same face. Remember that a plain cylinder drifts when air is lost - add a rod lock or pilot check valve if the load must stay put. Order the ACE80X120 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ACE80X120SB
- ✓ 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 ACP80X120SB FAQ
Push is 2513.3 N and pull 2356.2 N at 0.5 MPa; at 0.7 MPa push rises to 3518.6 N, with a theoretical maximum of 512.6 kgf at 1.0 MPa. It is double acting, 80 mm bore with a 20 mm male-threaded rod, 1/4" ports, operating range 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, air filtered to 40 um. The model is discontinued; the ACE80X120 is the current replacement.
It uses a hard-anodized aluminium body with threaded aluminium covers, an S45C hard-chrome rod, and fixed TPU bumpers at both ends that only decelerate the piston near end of stroke - they never hold a load. This version carries the optional -S magnet, so CMSE or DMSE reed or solid-state switches can be mounted for end-position detection. Mounting options include FA/FB flange, LB foot and CA/CB clevis. For new projects, order the ACE80X120 and confirm the ISO 21287 mounting dimensions.
