About the Airtac ACED Double-acting Compact Cylinder ACED20X45SB
The ACED20X45SB is a double acting, double-rod compact cylinder built to ISO 21287: a 20 mm bore with a 10 mm rod leaving both covers, so the 117.8 N output at 0.5 MPa is identical on every stroke because both sides work on the rod-side area. The male-threaded rod end (the B code) bolts straight into knuckles and fixtures, and the through-rod resists rotation and light side load while the rear rod can carry a sensor flag. Pressure range is 0.15-1.0 MPa (22-145 psi) with speed from 30-500 mm/s.
The hard-anodized aluminium body with an S45C hard-chrome-plated rod saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guarding where a full-length body will not fit. This S-code model carries the optional magnet, so CMSE or DMSE reed and solid-state switches can be clipped onto the body for end-of-stroke detection. A fixed TPU bumper at each end absorbs stroke-end impact, and with 117.8 N at 0.5 MPa the piston lifts about 6 kg vertically once you keep 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 (Ø20mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 118 N |
| 0.7 MPa | 165 N |
| Max (@1.0 MPa) | 24 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 ACED20X45SB Is Used
Pick-and-place on small assembly cells
The through-rod gives a symmetric mount for gripper tooling on electronics assembly heads, with the 45 mm stroke covering short part-transfer moves and the rear rod driving a flag past a CMSE switch.
Pusher on packaging lines
Equal 117.8 N force in both directions makes the ACED20X45SB a clean fit for carton push-and-return stations on blister or carton packers, where the male thread picks up a simple pusher plate.
Slide actuation in lab automation
The short ISO 21287 body tucks under low-profile instrument covers, and the fitted magnet with DMSE switches confirms home and end positions on sample-handling slides moving at 30-500 mm/s.
Is the Airtac ACED Double-acting Compact Cylinder ACED20X45SB the Right Cylinder?
At 117.8 N per direction (0.5 MPa) this 20 mm bore suits clamping and transfer tasks up to roughly 70 N of real work, leaving margin for friction and pressure drop. Step down to the 16 mm bore (75.4 N at 0.5 MPa) for lighter tooling, or up to the 25 mm bore (206.2 N) when the load grows. The 45 mm stroke sits well inside the 100 mm standard range for bore 20, so it ships as a catalogue item. Because a plain double-rod cylinder drifts when air is lost, add a rod lock or pilot check valve if the load must be held. Mounting: FA/FB flange, LB foot and FTC brackets plus I/Y rod knuckles fit the ISO 21287 face, and the fitted magnet accepts 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 ACED20X45SB FAQ
Yes. Because a rod exits both covers, both strokes use the rod-side area, so force is equal either way: 117.8 N at 0.5 MPa and 164.9 N at 0.7 MPa, with a maximum of 24 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 runs 30-500 mm/s.
It is an ISO 21287 compact cylinder whose short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, ideal for tight gantries and guards. FA/FB flanges, LB foot and FTC brackets plus I/Y rod knuckles bolt to the standard face. This model carries the optional -S magnet, so CMSE / DMSE switches can be fitted for position sensing; a fixed TPU bumper at each end absorbs end-of-stroke impact.
