About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-30
A double acting ISO 21287 compact cylinder, the ACEJ63X90-30 pairs a 63 mm bore with a 90 mm stroke that an external stop screw trims anywhere in a 30 mm window, giving a usable extend range of 60-90 mm on site. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa those figures rise to 2182.1 N and 2041.3 N, with a theoretical peak of 317.9 kgf at 1.0 MPa. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into gantries and guarding where a full-length body will not fit.
Plan around roughly 935 N of real work at 0.5 MPa (about 60% of the push rating), which corresponds to lifting about 95 kg vertically - halve that to about 48 kg if you want a 2:1 margin on a vertical lift. The hard-anodized aluminium body carries a 16 mm S45C hard-chrome rod with an M10x1.5 female thread, a fixed TPU bumper at each end absorbs end-of-stroke shock, and FA flange or LB foot mounts bolt to the standard ISO 21287 face. Speed range is 30-500 mm/s.

Where the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-30 Is Used
Press-fit bushings in gearbox housings
The 1558.6 N push at 0.5 MPa (2182.1 N at 0.7 MPa) seats automotive bushings in aluminium housings, and the 30 mm window lets you trim the 90 mm stroke to match each fixture depth.
Palletized part lift-and-lower station
Lifting about 48 kg vertically with a 2:1 margin, the cylinder handles machined aluminum pallets on an assembly line, with the short ISO 21287 body fitting under low guard rails.
Stop-and-release gate on a bottling conveyor
Extending 60-90 mm as trimmed on site, the rod pushes a gate across a PET bottle lane; the fixed TPU bumpers quiet the gate at both ends of travel.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-30 the Right Cylinder?
At 1558.6 N push at 0.5 MPa this 63 mm bore sits between the 50 mm (981.7 N) and 80 mm (2513.3 N) sizes - step down for lighter clamping, up if your load exceeds about 935 N of planned working force. The stop screw shortens the extend stroke only; it is a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost. FA flange and LB foot mountings plus I/Y rod knuckles fit standard fixtures, and if you need position feedback order the -S variant so CMSE / DMSE switches can sense the piston - this model has no magnet fitted.
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 ACEJ63X90-30 FAQ
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa, 2182.1 N push and 2041.3 N pull; theoretical maximum is 317.9 kgf at 1.0 MPa. The -30 code is a 30 mm adjustment window: an external stop screw shortens the 90 mm extend stroke by up to 30 mm, so the usable range is 60-90 mm. It cannot lengthen the stroke past 90 mm, and the stop is an end stop only - it does not hold a load if air pressure is lost. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, 16 mm hard-chrome S45C rod, M10x1.5 female rod thread and a 1/8" air port. FA flange and LB foot mountings bolt to the standard face. Position sensing requires the optional -S magnet code - this model has no magnet, so order ACEJ63X90-30S if you want CMSE or DMSE switches to detect piston position.
