Airtac ACED Double-acting Compact Cylinder ACED40X50B
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED40X50B is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø40mm bore and 50mm 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 ACED40X50B
The ACED40X50B is a double acting, double-rod ISO 21287 compact cylinder: a 12 mm piston 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 BOTH directions - push and pull are identical because both strokes work on the rod-side area. The B code gives a male rod thread on each end, and a fixed TPU bumper at each cover absorbs end-of-stroke shock.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight guarding and fixture plates. The hard-anodized aluminium body carries a roller-burnished bore, the S45C rod is hard-chrome plated, and the through-rod resists rotation and side load while the rear rod can carry a sensor flag. For real work, plan on roughly 343 N (about 35 kgf) of usable force at 0.5 MPa, which is a vertical lift of around 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 ACED40X50B Is Used
Symmetric jig clamping
The male-threaded through-rod lets a clamp fixture hang off both ends of a welding jig, gripping a bracket from two sides with an equal 571.8 N at 0.5 MPa.
Push-pull transfer slide
On a packaging line transfer slide, the double rod gives identical force in each stroke direction, so a 50 mm shuttle moves trays forward and back at the same 30-500 mm/s speed.
Rear-rod flag position check
Mount a flag on the back rod of a gate or door interlock so a proximity sensor reads stroke position, with the front rod doing the work - order the -S version for internal CMSE / DMSE switches instead.
Is the Airtac ACED Double-acting Compact Cylinder ACED40X50B the Right Cylinder?
At 571.8 N per direction, the 40 mm bore sits between the 32 mm (345.6 N) and 50 mm (881.2 N) classes - step down for lighter clamping, up for heavier pressing. Stroke 50 mm is well inside the 200 mm maximum standard stroke for this bore. If the load must stay put when air is lost, add a rod lock or pilot check; this cylinder drifts when depressurized. FA/FB flange, LB foot and FTC brackets plus I/Y rod knuckles bolt to the ISO 21287 face. Sensors need the optional -S magnet code (CMSE / DMSE); this non-S model has no magnet fitted.
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 ACED40X50B FAQ
Because a rod exits both covers, both strokes use the rod-side area and the force is equal in both directions: 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 pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed range 30-500 mm/s, and the port is 1/8" (PT thread on this model).
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and a fixed TPU bumper at each end absorbs end-of-stroke shock. FA/FB flange, LB foot and FTC brackets plus I/Y rod knuckles bolt straight to the standard face. Position switches (CMSE / DMSE) work only when you order the optional -S magnet code; the ACED40X50B without -S carries no magnet.
