This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ASE80X20, 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 ASP Single Acting Guided Compact Cylinder ASP80X20
The AirTAC ASP Single Acting Guided Compact Cylinder ASP80X20 is a single acting, push (spring return) DIN-standard tight/compact air cylinder with a Ø80mm bore and 20mm stroke, 1/4" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ASE80X20 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ASP Single Acting Guided Compact Cylinder ASP80X20
A single acting push cylinder with spring return, the discontinued ASP80X20 extends its 20 mm rod with compressed air and lets the internal spring pull it home when pressure drops. Its 80 mm bore delivers 2316.2 N of push at 0.5 MPa (3321.5 N at 0.7 MPa), already net of the spring, so one air line is all the plumbing you need. The hard-anodized aluminium body follows the ISO 21287 short format, cutting roughly 50% of the mounting length compared with an ISO 15552 profile cylinder.
The fixed TPU bumper at each end simply decelerates the rod. Note there is no magnet fitted on this code; the optional -S version adds one so CMSE or DMSE switches can sense position. This model is discontinued, and the current-production direct is the ASE80X20 - confirm the ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ASE80X20 (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 (spring return) |
|---|---|
| 0.5 MPa | 2316.2 N |
| 0.7 MPa | 3321.5 N |
Single-acting push: air extends the rod; the return spring retracts it. Forces already net the spring; minimum working pressure is 0.2 MPa.

Where the Airtac ASP Single Acting Guided Compact Cylinder ASP80X20 Is Used
Press-fit of bearing sleeves
The 2316.2 N push at 0.5 MPa seats small bearing sleeves or bushings into housings on a short 20 mm travel, with the spring retracting the tooling between cycles.
Clamping on a machining fixture
A hydraulic fixture on a CNC lathe uses the 80 mm bore to clamp a cast bracket, relying on about 1390 N of usable force and the compact body that fits where a full-length cylinder cannot.
Ejecting parts from a mold
In a small injection mold, air at 0.5 MPa pushes finished caps off the core; on air loss the spring retracts the ejector plate so the next shot can close safely.
Replacing the Airtac ASP Single Acting Guided Compact Cylinder ASP80X20 with the ASE80X20
At 80 mm bore this is near the top of the ASP range: 2316.2 N push at 0.5 MPa against 1420.5 N from a 63 mm bore, while the 100 mm bore reaches 3640.7 N if you need more. Choose the 80 if your fixture has the space and the 63 falls short of your clamping or pressing force. The 20 mm stroke suits short-travel work only; do not plan long strokes on a spring-return unit. Mounting brackets (FA/FB flange, LB foot, CA/CB clevis) and the optional -S magnet for CMSE / DMSE switches should be selected at order time. Because the spring drives the rod back on air loss, this cylinder cannot hold a mid-stroke position. Order the ASE80X20 as the current replacement.
Replacement checklist
- ✓ Current-production ACE → ASE80X20
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ASP Single Acting Guided Compact Cylinder ASP80X20 FAQ
This single acting push cylinder gives 2316.2 N at 0.5 MPa and 3321.5 N at 0.7 MPa, both already net of the return spring. Working pressure is 0.2-1.0 MPa (28-145 psi), with 0.2 MPa as the minimum to overcome the spring; proof pressure is 1.5 MPa (215 psi). Speed range is 50-500 mm/s and the fluid must be air filtered to 40 um.
The hard-anodized aluminium body follows the ISO 21287 short format, saving about 50% of the mounting length of an ISO 15552 profile cylinder, with FA/FB flange, LB foot and CA/CB clevis options and a fixed TPU bumper at both ends. The ASP80X20 is discontinued; the current-production direct is the ASE80X20 in the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping.
