About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-50SB
The ACEJ63X90-50SB is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 90 mm stroke by up to 50 mm on site, giving a usable range of 40-90 mm without changing the cylinder. At 0.5 MPa the 63 mm bore delivers 1558.6 N on the push stroke and 1458.1 N on the pull stroke, rising to 2182.1 N push at 0.7 MPa. The male rod thread (B code) and 1/8" port suit standard ISO 21287 fixtures, and the -S magnet this model carries lets CMSE / DMSE switches report end positions.
Because the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, it slots into tight clamping stations and gantry frames where a full-length body will not fit. In practice, plan for roughly 935 N of real work at 0.5 MPa (about 0.6 of the push rating), which is a vertical lift of around 95 kg - or about 47 kg with a 2:1 margin. A fixed TPU bumper at each end absorbs end-of-stroke energy, and the hard-anodized aluminium body with S45C hard-chrome rod resists wear in 30-500 mm/s duty.

Where the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-50SB Is Used
Press-station clamping
Trim the extend stroke from 90 mm down to 40 mm on the stop screw to match fixture depth on an aluminium die-casting clamping station, using about 935 N of usable push at 0.5 MPa.
Pallet-stacker lift assist
With roughly 95 kg of vertical lift equivalent at 0.5 MPa (about 47 kg at a 2:1 margin), the 63 mm bore raises pallet-guiding gates on warehouse conveyor lines.
CNC part ejector
The male rod thread and 1558.6 N push force eject machined housings from a CNC fixture, with CMSE switches on the fitted -S magnet confirming eject and retract.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-50SB the Right Cylinder?
Size against the 0.5 MPa push figure: the 50 mm bore gives 981.7 N push, while the 80 mm bore reaches 2513.3 N - the 63 mm at 1558.6 N sits between them for medium clamping and pressing loads. Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock, so the piston still drifts if air is lost. FA flange, LB foot and I/Y rod knuckles bolt to the ISO 21287 face; the -S magnet for CMSE / DMSE switches is already fitted on this model.
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 ACEJ63X90-50SB 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, with a theoretical maximum of 317.9 kgf at 1.0 MPa. The -50 code is a 50 mm adjustment window: an external stop screw shortens the 90 mm extend stroke by up to 50 mm, so the working range is 40-90 mm. The stop is an end stop only - it never holds a load if air pressure drops.
It is an ISO 21287 compact cylinder whose short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at both ends and a hard-anodized aluminium body. FA flange, LB foot and I/Y rod knuckles mount on the standard ISO 21287 face. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be clipped into the body slots; port is 1/8" and the rod thread is male.
