Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X50-10SB
The AirTAC ACEJ12 Adjustable Compact Cylinder ACEJ12X50-10SB is a genuine double acting, double rod, adjustable stroke ISO 21287 compact air cylinder with a Ø12mm bore and 50mm stroke, M5×0.8 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 ACEJ12 Adjustable Compact Cylinder ACEJ12X50-10SB
The ACEJ12X50-10SB is a double acting AirTAC compact cylinder to ISO 21287 with an adjustable extend stroke: an external stop screw trims the 50 mm stroke by up to 10 mm, giving a usable range of 40-50 mm without changing the cylinder.
The hard-anodized aluminium body with an S45C hard-chrome plated 6 mm rod keeps the mounting length about 50% shorter than an ISO 15552 profile cylinder, so it slots into tight pick-and-place heads and small fixtures. The male (B) rod thread suits external rod couplings, the fitted -S magnet works with CMSE / DMSE switches, and a fixed TPU bumper at each end absorbs end-of-stroke impact. Operating range is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, temperature -20 to +70 C.

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 (Ø12mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 42 N |
| 0.7 MPa | 59 N |
| Max (@1.0 MPa) | 9 kgf |
ACEJ is double-rod: the rear rod that carries the stroke adjuster exits the rear cover, so both piston faces lose rod area. The rod-side (annular) area is used for both directions (conservative).

Where the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X50-10SB Is Used
Small-part reject kicker
Mounted beside a bottling line conveyor, the 12 mm bore kicks underweight vials off the belt; the fitted magnet and a CMSE switch confirm the kick on every cycle at up to 500 mm/s.
Is the Airtac ACEJ12 Adjustable Compact Cylinder ACEJ12X50-10SB the Right Cylinder?
The stop screw is a mechanical end stop only - on air loss the piston can still drift, so do not rely on it to hold a load. Foot (LB) or flange (FA) mounting and the optional -S magnet for CMSE / DMSE switches make fixture integration straightforward; this model already carries the magnet and the male rod thread.
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 ACEJ12 Adjustable Compact Cylinder ACEJ12X50-10SB FAQ
Theoretical maximum is 11.5 kgf at 1.0 MPa. Bore is 12 mm, stroke 50 mm adjustable down to 40 mm via the -10 stop screw, port M5x0.8, rod 6 mm with male thread, speed 30-500 mm/s, operating pressure 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi).
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, S45C hard-chrome rod and fixed TPU bumpers at both ends. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be clipped onto the body slots for end-of-stroke detection. FA flange and LB foot mounts bolt to the standard ISO 21287 face.
