About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-75SB
A double acting ISO 21287 compact cylinder with a field-adjustable extend stroke, the ACEJ63X90-75SB pairs a 63 mm bore with a 90 mm stroke and a 75 mm trim window. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N, rising to 2182.1 N at 0.7 MPa, with a theoretical ceiling of 317.9 kgf at 1.0 MPa. The male rod thread (B code) and PT ports suit direct tooling attachment. Its short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into presses, guards and gantries where a full-length body will not fit.
Because the -S magnet is fitted on this model, CMSE or DMSE reed and solid-state switches can be clamped anywhere along the body for end-of-travel or intermediate sensing. The hard-anodized aluminium body carries a roller-burnished bore, the S45C hard-chrome rod resists wear, and a fixed TPU bumper at each end absorbs end-of-stroke shock. Run it on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, from -20 to +70 C. As a sizing rule, keep real work near 935 N at 0.5 MPa, which is roughly 95 kg lifted vertically with a 2:1 margin.

Where the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-75SB Is Used
Clamping of machined housings
On a CNC fixture for aluminium gearbox housings, the 1558.6 N push at 0.5 MPa holds the part against hard stops while the male rod thread drives a custom clamp arm.
Pallet strapper actuation
In a warehouse strapping head, the 75 mm window lets maintenance trim the extend stroke from 90 mm down to 15 mm to match different strap heights without changing the cylinder.
Small press ejection
A benchtop forming press uses the 90 mm stroke to eject stamped brackets, with CMSE switches on the fitted magnet confirming full retract before the next cycle.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-75SB the Right Cylinder?
At 63 mm bore you sit in the mid-heavy band: 1558.6 N push at 0.5 MPa. If your load needs under 981.7 N, the 50 mm bore costs less in air; if you need beyond 2513.3 N, step up to the 80 mm bore. The stop screw trims the extend stroke anywhere between 15 and 90 mm, so one unit can serve several fixture positions, but remember it is a mechanical end stop only: on air loss the piston still drifts, so it is not a mid-stroke lock or load-holding brake. Bolt FA flange or LB foot brackets to the ISO 21287 face, add I or Y rod knuckles on the male thread, and order CMSE or DMSE switches to read positions via the fitted -S magnet.
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 ACEJ63X90-75SB FAQ
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa push rises to 2182.1 N, and the theoretical maximum is 317.9 kgf at 1.0 MPa. The -75 code is a 75 mm adjustment window: an external stop screw shortens the 90 mm extend stroke by up to 75 mm, giving a usable range of 15-90 mm. It shortens the stroke only and acts as a mechanical end stop, not a mid-stroke lock. Operating range is 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits tight jigs and guards. A fixed TPU bumper at each end absorbs end-of-stroke energy. This model carries the optional -S magnet, so CMSE or DMSE reed or solid-state switches can be mounted along the body slots. FA flange and LB foot brackets plus I and Y rod knuckles bolt straight to the ISO 21287 face; the rod end is male thread and the ports are 1/8" PT.
