The AirTAC Airtac ACED Double-acting Compact Cylinder ACED125X225B is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø125mm bore and 225mm 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.
A heavy-duty double acting compact cylinder built to ISO 21287, the ACED125X225B pushes a 125 mm bore through a 225 mm stroke with a 25 mm rod exiting BOTH covers. Because both strokes work on the rod-side area, output is a symmetric 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa - push and pull are identical, so there is no weak direction to design around. The male rod thread (B code) bolts straight to your tooling.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters when a 225 mm stroke has to fit inside a press frame, weld fixture or gantry with limited depth. A rule of thumb for real work: plan on roughly 3534 N (about 60% of rating) at 0.5 MPa, which is around 360 kgf - so with a 2:1 margin this cylinder lifts about 180 kg vertically. The through-rod also resists rotation and side load, and the rear rod can carry a sensor flag. Air supply is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and a fixed TPU bumper absorbs end-of-stroke shock at both ends.

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 | 5890 N |
| 0.7 MPa | 8247 N |
| Max (@1.0 MPa) | 1201 kgf |
Double-rod: a rod exits both covers, so output force is equal in both directions (rod-side area used).

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.
Delivers 5890.5 N per direction at 0.5 MPa to seat large castings or stampings in a press die before the main forming stage, with the male rod thread taking a forged clamp platen directly.
The 225 mm stroke clears robot loading in an automotive weld cell, and the short ISO 21287 body fits inside the fixture frame where a full-length profile cylinder would not.
A rod on each end lets the rear rod carry a counterweight or sensor flag while the front lifts about 180 kg vertically with a 2:1 margin on the 0.5 MPa force rating.
At 5890.5 N per direction at 0.5 MPa, the 125 mm bore sits at the top of the ACED range - step down to the 100 mm bore (3769.9 N) for lighter press or clamp loads, or up if you need more than the 300 mm max standard stroke this bore allows. The 225 mm stroke is within standard range, so no made-to-order build is needed. This unit has no magnet: if you need CMSE or DMSE switch position feedback, order the -S code instead. Mount with FA/FB flanges, LB foot or FTC brackets plus I/Y rod knuckles on the ISO 21287 face. Note that a plain double-rod cylinder drifts when air is lost - add a rod lock or pilot check if the load must stay held.
Quick checklist
Yes - this is a double-rod cylinder, so a 25 mm rod exits both covers and every stroke uses the rod-side area. Output is 5890.5 N at 0.5 MPa and 8246.7 N at 0.7 MPa, equal in both directions, with a maximum of 1201.3 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, running at 30-500 mm/s on air filtered to 40 um.
A hard-anodized aluminium body with an S45C hard-chrome-plated rod, threaded aluminium covers, and a fixed TPU bumper at each end that decelerates the piston at stroke ends. The body saves about 50% of the mounting length of an ISO 15552 profile cylinder. Mounting is via FA/FB flange, LB foot or FTC brackets with I/Y rod knuckles. This version has no magnet - order the -S code to enable CMSE / DMSE switches.
