Airtac ACED Double-acting Compact Cylinder ACED50X20B
The AirTAC Airtac ACED Double-acting Compact Cylinder ACED50X20B is a genuine double acting, double rod ISO 21287 compact air cylinder with a Ø50mm bore and 20mm 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 ACED50X20B
A double acting compact cylinder built to ISO 21287, the ACED50X20B pushes a 16 mm rod out of BOTH covers, so its 50 mm bore delivers 881.2 N at 0.5 MPa in each direction - the rod-side area is identical on both strokes. At 0.7 MPa that rises to 1233.7 N, and the bore tops out at 179.7 kgf at 1.0 MPa. The male-threaded rod end (the B code) bolts straight into knuckles and fixtures without an adapter.
The short hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into tight press fixtures and sliding gates. A fixed TPU bumper at each end absorbs end-of-stroke shock, and the through-rod resists rotation and light side load while giving you a rear rod for a sensor flag. Speed range is 30-500 mm/s.

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 ACED50X20B Is Used
Short-stroke press fixture
The 20 mm stroke and 881.2 N of symmetrical force suit a bench-top staking or marking press where the part is pre-positioned and only a short push is needed.
Reciprocating slider on a packaging line
Equal force in both directions drives a pusher bar back and forth at 30-500 mm/s, and the second rod end keeps the carriage square without extra guides.
Is the Airtac ACED Double-acting Compact Cylinder ACED50X20B the Right Cylinder?
Size between neighbours: the 40 mm bore gives 571.8 N at 0.5 MPa, while stepping up to 63 mm raises it to 1458.1 N - pick the 50 mm when your clamp or press needs the 881.2 N class with a short 20 mm stroke. Remember that a plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check if the load must stay put. Mount with FA/FB flange, LB foot or FTC brackets plus I/Y rod knuckles on the ISO 21287 face. This code has no magnet; order the -S version if you need CMSE / DMSE switch position sensing.
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 ACED50X20B FAQ
Output is equal in both directions because a rod exits each cover: 881.2 N at 0.5 MPa and 1233.7 N at 0.7 MPa, with a maximum of 179.7 kgf at 1.0 MPa.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body, S45C hard-chrome-plated 16 mm rod, 1/8" PT ports and a fixed TPU bumper at both ends; the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder. Switches are not possible on this code - the magnet is the optional -S version, which accepts CMSE / DMSE switches; FA/FB flange, LB foot and FTC mounts bolt straight to the face.
