Airtac ACED Double-acting Compact Cylinder ACED40X120SB
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED40X120SB is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø40mm bore and 120mm 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 ACED40X120SB
A double acting AirTAC compact cylinder built to ISO 21287, the ACED40X120SB pushes a 12 mm hard-chrome rod out of 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 - no push/pull imbalance to design around. The male rod thread (B code) suits external nuts and knuckles, and the fitted -S magnet lets CMSE / DMSE switches report end positions directly.
The hard-anodized aluminium body with roller-burnished bore and S45C rod runs at 0.15-1.0 MPa (22-145 psi) and 30-500 mm/s, with a fixed TPU bumper at each end. Because the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, it slots into tight gantries and guarding. Practical sizing: at 0.5 MPa the through-rod will lift roughly 29 kg vertically with a 2:1 margin, so match it to parts in that weight class.

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 ACED40X120SB Is Used
Fixture clamping on CNC pallets
Equal 571.8 N force both ways lets one cylinder clamp and unclamp a pallet without recalculating pull force, and the 120 mm stroke clears the load path.
Pusher arm on packaging lines
The through-rod resists rotation on a pusher blade, while the fitted -S magnet with a CMSE switch confirms home and extended positions at up to 500 mm/s.
Lift-assist in electronics assembly
About 29 kg of vertical lift at a 2:1 margin covers PCB trays and small fixtures; the compact body fits where an ISO 15552 profile cylinder is too long.
Is the Airtac ACED Double-acting Compact Cylinder ACED40X120SB the Right Cylinder?
For jobs needing 571.8 N at 0.5 MPa, bore 40 is the pick; step down to ACED32 (345.6 N) for lighter clamps or up to ACED50 (881.2 N) when the load grows. The 120 mm stroke sits inside the 200 mm standard range for this bore, so no made-to-order build is needed. FA/FB flanges, LB feet and FTC brackets bolt to the ISO 21287 face, and I/Y knuckles suit the male thread. Note the piston will drift if air is lost - add a rod lock or pilot check where a load must stay held.
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 ACED40X120SB FAQ
Being double rod, force is equal in both directions: 571.8 N at 0.5 MPa and 800.5 N at 0.7 MPa on each stroke, with a maximum of 116.6 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the 1/8" port depends on the 40 mm bore.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with FA/FB flange, LB foot and FTC brackets plus I/Y knuckles for the male thread. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be clipped to the body slots; a fixed TPU bumper at each end absorbs end-of-stroke energy.
