The AirTAC Airtac ASE Single Acting Plunger Type Compact Air Cylinder ASE80X25SB is a genuine single acting, push (spring return) ISO 21287 compact air cylinder with a Ø80mm bore and 25mm stroke, 1/4" air ports and a hard-anodized aluminium body. Its short compact envelope saves about 50% of the mounting length of an ISO 15552 profile cylinder.
The ASE80X25SB is a single acting push cylinder in AirTAC's ISO 21287 compact series: air extends the 20 mm hard-chromed S45C rod and the return spring retracts it, so one air line does the whole job. At 0.5 MPa this 80 mm bore delivers 2316.2 N of push, already net of the spring, rising to 3321.5 N at 0.7 MPa. The B code gives a male rod thread and the S code fits the optional magnet, so CMSE / DMSE switches can read end positions. Minimum working pressure is 0.2 MPa, which is what it takes to beat the spring.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why heavy compact strokes like this one fit inside press fixtures and guarding where a full-length body will not. A roller-burnished, hard-anodized aluminium body resists wear, and a fixed TPU bumper at each end absorbs end-of-stroke energy. For planning, treat roughly 1390 N (about 60% of the 0.5 MPa rating) as the working force, and remember the spring returns the rod home on air loss - it lifts about 118 kg vertically with a 2:1 margin.

Specifications follow the official AirTAC ACE-series (ISO 21287) datasheet. Body: hard-anodized aluminium alloy; piston rod: S45C carbon steel with hard-chrome plating. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G. A built-in magnet is OPTIONAL — add the -S code to fit CMSE / DMSE position sensors.
| 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. Single-acting strokes are short (Ø12 to 10 mm, Ø16-100 to 25 mm).
| ASE | ISO 21287 compact cylinder (single-acting push, spring-return). |
|---|---|
| 80 | Bore size in mm. |
| ×25 | Stroke length in mm. |
| S | Optional built-in magnet for CMSE / DMSE sensors (omit for no magnet). |
| B | Rod type: B = male thread; blank = female thread. |
ACE-family variants: ACE (double acting), ASE / ATE (single acting push / pull), ACED (double rod), ACEJ (adjustable stroke), TACE / TACED (non-rotating twin-guide yoke). Mounting accessories: FA / FB flange, LB foot, CA / CB clevis, CR, SDB pivot, FTC; plus I and Y knuckles. Thread PT (blank) / G.
A 25 mm stroke with 2316.2 N at 0.5 MPa is enough to crimp terminals or stamp batch codes on aluminium brackets inside a compact press head.
Spring return drops the gate to its safe position the moment air is lost, and the short body bolts to the gate frame where a full-length profile cylinder will not fit.
The male rod thread takes a Y knuckle to clamp cartons against the sealing bar, with CMSE switches confirming the clamp is home.
Size up or down by force: the 63 mm bore gives 1420.5 N at 0.5 MPa, while the 100 mm bore reaches 3640.7 N, so this 80 mm model sits squarely in the 2316.2 N class. Strokes for bore 80 run up to 25 mm in the single-acting range, and speed is 50-500 mm/s. Bolt FA/FB flanges, LB feet, CA/CB clevis or SDB pivot brackets to the ISO 21287 face, add I or Y rod knuckles for the male thread, and order CMSE / DMSE switches only because this -S model carries the magnet.
Quick checklist
Push is 2316.2 N at 0.5 MPa and 3321.5 N at 0.7 MPa, both already net of the return spring. Operating pressure is 0.2-1.0 MPa (28-145 psi) with 1.5 MPa (215 psi) proof, and 0.2 MPa is the minimum to overcome the spring. Stroke is 25 mm, speed 50-500 mm/s, air filtered to 40 um, temperature -20 to +70 C, with a 1/4" port and male rod thread.
The compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits tight fixtures, and FA/FB, LB, CA/CB, CR, SDB or FTC brackets bolt straight to the standard face. Because this model carries the -S magnet, CMSE / DMSE reed or solid-state switches mount in the body slots to signal rod position; a fixed TPU bumper at each end absorbs end-of-stroke energy.
