Airtac ACED Double-acting Compact Cylinder ACED40X45
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED40X45 is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø40mm bore and 45mm 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.

About the Airtac ACED Double-acting Compact Cylinder ACED40X45
The ACED40X45 is a double acting, double-rod compact cylinder built to the ISO 21287 short-body format. A 12 mm hard-chrome-plated S45C rod exits BOTH covers, so the 40 mm bore delivers 571.8 N at 0.5 MPa and 800.5 N at 0.7 MPa in either direction - both strokes work on the rod-side area, so push and pull are identical. The through-rod also resists rotation and light side load, and the free back-end rod is a handy place to carry a sensor flag.
The hard-anodized aluminium body is about 50% shorter in mounting length than an ISO 15552 profile cylinder, which is why this size fits cramped pick-and-place gantries and guard-mounted jigs. Fixed TPU bumpers at each end absorb end-of-stroke shock, speed range is 30-500 mm/s, and the working envelope is 0.15-1.0 MPa (22-145 psi) with -20 to +70 C temperatures. At 0.5 MPa the 571.8 N rating equals about 58 kgf, so for vertical lifting plan on roughly 29 kg 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.
Theoretical Output Force (Ø40mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 572 N |
| 0.7 MPa | 800 N |
| Max (@1.0 MPa) | 117 kgf |
Double-rod: a rod exits both covers, so output force is equal in both directions (rod-side area used).

Where the Airtac ACED Double-acting Compact Cylinder ACED40X45 Is Used
Fixture clamping on CNC pallets
The 45 mm stroke clamps a machining fixture shut with 571.8 N at 0.5 MPa, and the short ISO 21287 body tucks under the pallet where a full-length profile cylinder would not fit.
Reciprocating transfer slides
With a rod on each cover, the ACED40X45 pushes a small conveyor transfer slide forward and back with identical 800.5 N at 0.7 MPa, and the rear rod can drive a flag past a position sensor.
Press-fit ejection in assembly heads
A 40 mm bore ejecting finished bushings from an assembly die gets about 58 kgf at 0.5 MPa; halving that still lifts roughly 29 kg of tooling vertically with margin.
Is the Airtac ACED Double-acting Compact Cylinder ACED40X45 the Right Cylinder?
For a 45 mm stroke with equal force both ways, the 40 mm bore gives 571.8 N at 0.5 MPa - enough for clamping or lifting parts up to about 29 kg vertically with a 2:1 margin. Step down to the 32 mm bore (345.6 N at 0.5 MPa) for lighter tooling, or up to the 50 mm bore (881.2 N at 0.5 MPa) when the load grows. Note that a plain double-rod cylinder will drift if air is lost; add a rod lock or pilot check valve where a load must be held. Mounting bolts straight onto the ISO 21287 face - FA/FB flange, LB foot or FTC brackets with I/Y rod knuckles - and if you need position sensing, order the -S code so CMSE / DMSE switches can read the optional magnet.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Short stroke fits the compact body
- ✓ Port/thread type (PT / G)
- ✓ Add -S if you need the magnet for sensors
- ✓ Rod type (female / male B) & mount (FA/LB/CA)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Compact body: keep the stroke short and avoid side load on the rod.
- check Do not dismantle the threaded front/back covers.
- check Keep speed within the rated range; the TPU bumper absorbs stroke-end energy.
- check Installation by qualified personnel per AirTAC docs.
Airtac ACED Double-acting Compact Cylinder ACED40X45 FAQ
Yes - this is a double-rod cylinder, so a 12 mm rod exits both covers and every stroke uses the rod-side area of the 40 mm bore. Output is 571.8 N at 0.5 MPa and 800.5 N at 0.7 MPa in either direction, equal push and pull, with a maximum of 116.6 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), and speed 30-500 mm/s.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so the ACED40X45 slots into tight gantries and guards. FA/FB flange, LB foot and FTC brackets plus I/Y rod knuckles bolt to the standard face. Position sensing needs the optional -S magnet code - without it there is no magnet and no switch can be read; with -S, CMSE or DMSE switches mount in the body slots. A fixed TPU bumper at each end absorbs end-of-stroke shock, but the cylinder never locks a load - use a rod lock or pilot check if air loss must not cause drift.
