About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ50X150-50SB
The ACEJ50X150-50SB is a double acting, adjustable-stroke compact cylinder built to ISO 21287: a 50 mm bore with a 150 mm stroke, a 16 mm hard-chrome-plated S45C rod and a male rod thread from the B code. At 0.5 MPa it pushes 981.7 N and pulls 881.2 N, rising to 1374.4 N on extension at 0.7 MPa. Its short hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight machine frames and fixtures. The -50 code adds a 50 mm adjustment window: an external stop screw trims the extend stroke anywhere between 100 and 150 mm on site, no disassembly needed.
The magnet from the -S option is fitted, so CMSE / DMSE reed or solid-state switches read end positions directly on the body slots. A fixed TPU bumper at each end absorbs end-of-stroke shock, the port is 1/8", and the cylinder runs at 0.15-1.0 MPa (22-145 psi) with speeds of 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 |
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 ACEJ50X150-50SB Is Used
Pick-and-place lift of machined housings
The pull force of 881.2 N at 0.5 MPa supports a vertical lift of roughly 60 kg with margin, ideal for lowering aluminium gearbox housings onto a machining pallet, with CMSE switches confirming top and bottom positions.
Stopper gates on packaging conveyors
A 150 mm stroke (trimmable to 100 mm) raises and lowers stopper blades on food and beverage conveyor lines, and the compact body fits under guarding where a full-length ISO 15552 profile cylinder would not.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ50X150-50SB the Right Cylinder?
If your tooling needs more than about 590 N of usable force, stay here; below that, the bore 40 saves space. The stop screw only shortens the extend stroke within the 50 mm window, so order the full 150 mm stroke even if you plan to run shorter. It is a mechanical end stop, not a mid-stroke lock, so the rod can drift if air is lost. FA flange, LB foot and I/Y rod knuckles bolt to the ISO 21287 face, and the fitted -S magnet lets CMSE / DMSE switches clip onto the body slots.
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 ACEJ50X150-50SB FAQ
It is double acting with an adjustable extend stroke: the -50 stop screw trims the 150 mm stroke by up to 50 mm, giving a usable range of 100-150 mm. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, fluid air filtered to 40 um, and the port is 1/8".
The ACEJ50X150-50SB uses a hard-anodized aluminium body with a hard-chrome-plated S45C rod and threaded aluminium covers, saving about 50% of the mounting length of an ISO 15552 profile cylinder. A fixed TPU bumper at each end absorbs end-of-stroke energy. The -S magnet is fitted on this model, so CMSE / DMSE reed or solid-state switches mount directly in the body slots to report end positions. FA flange, LB foot and I/Y rod knuckles attach to the standard ISO 21287 mounting face.
