About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-30B
The ACEJ63X90-30B is a double acting ISO 21287 compact cylinder with a 63 mm bore and a 90 mm stroke that an external stop screw can trim by up to 30 mm, giving a usable extend range of 60-90 mm. At 0.5 MPa it pushes with 1558.6 N and pulls with 1458.1 N, rising to 2182.1 N at 0.7 MPa. Its short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into presses, clamping fixtures and gantries where a full-length body will not fit.
The male rod thread (B code) on the 16 mm hard-chrome S45C rod bolts straight to standard tooling, and the hard-anodized aluminium body carries fixed TPU bumpers at both ends to soften the ends of travel. As a planning figure, treat roughly 935 N (about 0.6 of the push force) as the practical working force at 0.5 MPa, which corresponds to lifting around 79 kg vertically with a 2:1 margin. Running specs: 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, -20 to +70 C.

Where the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-30B Is Used
Clamping of machined housings
The 1558.6 N push at 0.5 MPa seats aluminium gearbox housings in a milling fixture, and the 60-90 mm adjustable window lets one cylinder serve several part heights.
Small press and forming station
With about 2182 N available at 0.7 MPa, the male-threaded rod drives a light swaging or marking die where a full-length ISO 15552 body would not fit the frame.
Vertical lift on palletizing cell
The rod can raise roughly 79 kg vertically with a 2:1 margin at 0.5 MPa, ideal for a pick-and-place gantry lifting small cartons between conveyor levels.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-30B the Right Cylinder?
At 63 mm this sits in the mid-heavy class: a 50 mm bore delivers 981.7 N push at 0.5 MPa while an 80 mm bore reaches 2513.3 N, so pick the 63 mm when your fixture needs roughly 900-950 N of usable force. Note that the stop screw only shortens the extend stroke and is not a mid-stroke lock - on air loss the piston still drifts, so add a separate clamp if the position must hold. Mounting options include FA flange and LB foot, plus I and Y rod knuckles on the male thread. If you need position feedback, order the -S variant to enable the optional magnet for CMSE / DMSE switches; 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 ACEJ63X90-30B FAQ
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa it pushes 2182.1 N and pulls 2041.3 N; 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 on site, 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 never holds a load on air loss.
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 rod, 1/8" PT ports and fixed TPU bumpers at both ends. Sensing requires the optional -S magnet code, which enables CMSE / DMSE switches; this model (no S code) has no magnet, so no switch can be mounted on it. Mounting: FA flange, LB foot, plus I/Y rod knuckles on the male thread.
