Airtac ACED Double-acting Compact Cylinder ACED50X45SB
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED50X45SB is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø50mm bore and 45mm 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 ACED50X45SB
A double acting compact cylinder built to ISO 21287, the ACED50X45SB pushes a 50 mm bore through a 45 mm stroke with a rod leaving both covers, so thrust is identical on the out-stroke and the return: 881.2 N at 0.5 MPa and 1233.7 N at 0.7 MPa either way. The hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder in mounting length, which is why it slots into tight robotics gantries and fixture plates. This -S version carries the magnet, so CMSE or DMSE reed and solid-state switches read position straight off the body slots.
The through-rod does more than push both ways: it resists rotation, tolerates modest side load, and the rear rod can carry a sensor flag or a second tool. A fixed TPU bumper at each end absorbs end-of-stroke shock, and the S45C hard-chrome-plated rod with male thread (B code) bolts into standard knuckles. Speed range is 30-500 mm/s on air filtered to 40 um.

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 (Ø50mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 881 N |
| 0.7 MPa | 1234 N |
| Max (@1.0 MPa) | 180 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 ACED50X45SB Is Used
CNC fixture clamping from both sides
The through-rod lets one cylinder clamp a machined housing against a fixed stop while the rear rod drives a locator pin, delivering 881.2 N per side at 0.5 MPa inside a 45 mm stroke envelope.
Bottling line pusher with position feedback
On a PET bottle conveyor, the male-threaded rod carries a pusher paddle and the fitted magnet feeds a DMSE switch to the PLC, confirming each 45 mm reject stroke at up to 500 mm/s.
Is the Airtac ACED Double-acting Compact Cylinder ACED50X45SB the Right Cylinder?
At 881.2 N per direction at 0.5 MPa, the 50 mm bore sits mid-range: step down to the 40 mm ACED (571.8 N) for lighter clamping, or up to the 63 mm (1458.1 N) when a heavier die or fixture needs the margin. Note that a plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check valve if the load must stay put. Mounting: FA/FB flanges, LB foot or FTC brackets bolt to the ISO 21287 face, with I and Y rod knuckles for the male-threaded ends; the fitted -S magnet means CMSE / DMSE switches work out of the box.
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 ACED50X45SB FAQ
Yes - the double-rod design means both strokes use the rod-side area, so output is equal either way: 881.2 N at 0.5 MPa, 1233.7 N at 0.7 MPa, and up to 179.7 kgf at the 1.0 MPa maximum. Operating pressure is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, speed 30-500 mm/s, and the 1/8" port matches the 50 mm bore.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, ideal for cramped machine frames. The S code means the magnet is fitted on this unit, so CMSE / DMSE switches can be clipped into the body slots for end-of-stroke signals; the B code gives a male rod thread on the 16 mm rods. A fixed TPU bumper at each end absorbs stroke-end shock, and FA/FB flange, LB foot or FTC mounts bolt straight on.
