Airtac ACED Double-acting Compact Cylinder ACED40X50SB
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED40X50SB 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 ACED40X50SB
A double acting compact cylinder built to ISO 21287, the ACED40X50SB pushes a 40 mm bore through a 50 mm stroke with a piston rod leaving BOTH covers. Because each stroke sees the rod-side area, output is identical in both directions: 571.8 N at 0.5 MPa and 800.5 N at 0.7 MPa. The B code gives a male rod thread, and the S code means the magnet is fitted, so CMSE or DMSE switches can be clamped anywhere along the body slots.
The hard-anodized aluminium body with an S45C hard-chrome plated rod runs at 0.15-1.0 MPa (22-145 psi) and 30-500 mm/s, with a fixed TPU bumper at each end. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight guards and fixtures. In practice, plan on roughly 343 N of usable push at 0.5 MPa, which lifts about 29 kg vertically 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 ACED40X50SB Is Used
Symmetric jig clamping
The through-rod lets a fixture clamp from either cover with the same 571.8 N at 0.5 MPa, ideal for machining pallets that load from both sides.
Conveyor gate pusher
A 50 mm stroke swings or pushes sorting gates on packaging lines at up to 500 mm/s, with the back-end rod carrying a sensor flag for position feedback.
Battery-lift test rig
With about 29 kg of vertical lift capacity at a 2:1 margin, the cylinder cycles EV battery trays on an assembly bench where headroom is limited.
Is the Airtac ACED Double-acting Compact Cylinder ACED40X50SB the Right Cylinder?
At 571.8 N per direction, bore 40 suits clamping and lifting in the 30-60 kg class. Step down to bore 32 (345.6 N at 0.5 MPa) for lighter jigs, or up to bore 50 (881.2 N) when the part is heavier. The 50 mm stroke sits well inside the 200 mm maximum standard stroke for this bore, so it ships as a catalogue item. Remember that a plain double-rod cylinder drifts when air is lost - add a rod lock or pilot check if the load must stay put. FA/FB flanges, LB feet, CA/CB clevises and FTC brackets bolt straight to the ISO 21287 face, and the fitted magnet pairs with CMSE / DMSE switches.
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 ACED40X50SB FAQ
It is a double-rod cylinder, so 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. Air supply is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed range 30-500 mm/s, and the 1/8" port depends only on the 40 mm bore.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, freeing space inside guards and gantries. The S code on this model means the magnet is fitted, so CMSE or DMSE reed or solid-state switches snap into the body slots for end-of-stroke detection. A fixed TPU bumper at each end absorbs end-of-stroke energy, and FA/FB, LB, CA/CB and FTC mounting hardware bolts straight on.
