About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ50X160-75SB
The ACEJ50X160-75SB is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 160 mm stroke by up to 75 mm, giving a usable range of 85-160 mm without changing the order code. At 0.5 MPa the 50 mm bore pushes 981.7 N and pulls 881.2 N, rising to 1374.4 N at 0.7 MPa, with a theoretical ceiling of 200.2 kgf at 1.0 MPa.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so this 160 mm stroke unit still fits shallow fixtures, sliding guards and gantry Z-axes. A hard-anodized aluminium body carries a hard-chrome plated S45C rod with a male thread (the B code), fixed TPU bumpers absorb end-of-stroke shock at both ends, and because this model carries the optional -S magnet, CMSE / DMSE reed or solid-state switches can be clipped straight onto the body.

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 |
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 ACEJ50~63 Adjustable Compact Air Cylinder ACEJ50X160-75SB Is Used
Stopper gate on a packaging conveyor
The 881.2 N pull at 0.5 MPa retracts a pop-up stopper reliably, while the compact body fits the shallow space under the frame where a full-length profile cylinder will not.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ50X160-75SB the Right Cylinder?
The 75 mm window suits jobs where the final stroke is tuned on the machine - set the stop screw anywhere in the 85-160 mm range. Remember the stop screw is a mechanical end stop only: on air loss the rod still drifts, so add a valve or lock for load holding. FA flange, LB foot and I/Y rod knuckles bolt to the ISO 21287 face, and the fitted -S magnet lets CMSE / DMSE switches report end positions. Port is 1/8" PT; rod thread is male.
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 ACEJ50~63 Adjustable Compact Air Cylinder ACEJ50X160-75SB FAQ
At 0.5 MPa it pushes 981.7 N and pulls 881.2 N; at 0.7 MPa those rise to 1374.4 N and 1233.7 N, with a theoretical maximum of 200.2 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the extend stroke is adjustable from 85 to 160 mm via the stop screw.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so a 160 mm stroke still fits tight fixtures. FA flange, LB foot and I/Y rod knuckles bolt to the standard face, and the male-threaded rod (B code) accepts standard rod accessories. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches mount directly on the body slots; fixed TPU bumpers at both ends absorb end-of-stroke energy.
