The AirTAC Airtac ACED Double-acting Compact Cylinder ACED32X25SB is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø32mm bore and 25mm stroke, 1/8" 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.
A double acting compact cylinder with a rod through both covers, the ACED32X25SB delivers 345.6 N at 0.5 MPa in EACH direction, because both strokes work on the rod-side area. At 0.7 MPa that rises to 483.8 N either way, with a peak of 70.5 kgf at 1.0 MPa. The B code gives a male rod thread on both ends, and the fitted -S magnet accepts CMSE / DMSE switches for end-of-stroke sensing.
The hard-anodized aluminium body with a roller-burnished bore carries an S45C hard-chrome plated rod, and a fixed TPU bumper at each end absorbs end-of-stroke shock. As an ISO 21287 compact build it saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding. A practical planning figure: treat roughly 207 N (about 21 kg vertical) as your usable working force at 0.5 MPa, leaving margin for friction and pressure drop. Speed range is 30-500 mm/s on air filtered to 40 um.

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 | Force (both ways) |
|---|---|
| 0.5 MPa | 346 N |
| 0.7 MPa | 484 N |
| Max (@1.0 MPa) | 70 kgf |
Double-rod: a rod exits both covers, so output force is equal in both directions (rod-side area used).

| ×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.
The 25 mm stroke shuttles small machined brackets between two nests on a CNC tending cell; 345.6 N both ways means the same grip force on approach and return.
Male threads on both rods let a packaging machine drive two slides from one cylinder body, keeping equal force and timing on the push and pull stroke.
With the fitted -S magnet, CMSE or DMSE switches confirm full clamp and full retract on an electronics assembly press fixture running at 0.5 MPa.
At 32 mm bore you sit mid-range: the 25 mm bore gives 206.2 N at 0.5 MPa and the 40 mm bore reaches 571.8 N, so step up only if your tooling mass demands it. The through-rod resists rotation and light side load, and the rear rod can carry a sensor flag or a second tool. Note that with no air applied the piston drifts freely - for a held vertical load add a rod lock or pilot check valve. Mount with FA/FB flanges, LB feet or FTC brackets plus I/Y rod knuckles on the standard ISO 21287 face; PT ports are standard, order the G option for BSPP.
Quick checklist
Yes - the double-rod design means both strokes use the rod-side area, so force is equal each way: 345.6 N at 0.5 MPa, 483.8 N at 0.7 MPa, and a maximum of 70.5 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, ideal for cramped gantries. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches clip into the body slots; a fixed TPU bumper at each end absorbs end-of-stroke impact.
