Airtac ACED Double-acting Compact Cylinder ACED40X70B
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED40X70B is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø40mm bore and 70mm 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 ACED40X70B
A double acting compact cylinder with a rod leaving both covers, the ACED40X70B pushes and pulls with identical output: 571.8 N at 0.5 MPa and 800.5 N at 0.7 MPa in either direction, because both strokes work on the rod-side area. The male rod thread (B code) on each 12 mm rod end bolts straight to tooling, and a fixed TPU bumper at each end absorbs end-of-stroke shock. Running on 0.15-1.0 MPa (22-145 psi) air at 30-500 mm/s, it suits fast pick-and-place work.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so the 70 mm stroke fits inside tight guards and slide assemblies. The hard-anodized aluminium body carries FA/FB flange, LB foot and FTC brackets plus I/Y rod knuckles. This unit has no magnet; order the -S code if you need CMSE / DMSE switch position sensing.

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 ACED40X70B Is Used
Reciprocating slide on a packaging line
The through-rod drives a pusher plate from either side with the same 571.8 N at 0.5 MPa, while the rear rod carries a sensor flag on a repeatable cycle at up to 500 mm/s.
Fixture clamp inside a CNC guard
The short ISO 21287 body needs about half the mounting length of an ISO 15552 profile cylinder, so the 70 mm stroke clamps workpieces where a full-length body cannot reach.
Is the Airtac ACED Double-acting Compact Cylinder ACED40X70B the Right Cylinder?
For a 70 mm stroke needing equal force both ways, this 40 mm bore gives 571.8 N at 0.5 MPa. Step down to ACED32 (345.6 N at 0.5 MPa) for lighter clamping, or up to ACED50 (881.2 N) for heavier tooling. Remember the piston drifts if air is lost, so add a rod lock or pilot check valve for a held load. Choose the B male thread for direct tooling attachment, and add the -S option if CMSE / DMSE switches will be fitted later.
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 ACED40X70B FAQ
Yes. Because a rod exits both covers, both strokes use the rod-side area, so force is equal either way: 571.8 N at 0.5 MPa and 800.5 N at 0.7 MPa, with a maximum of 116.6 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with proof pressure of 1.5 MPa (215 psi).
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body, S45C hard-chrome plated rods, 1/8" ports and a fixed TPU bumper at each end. Sensing is not fitted as standard: order the -S version to get the optional magnet, which allows CMSE or DMSE switches to be clipped into the body slots. Mounting brackets (FA/FB flange, LB foot, FTC) and I/Y rod knuckles bolt to the standard face.
