About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X80-20SB
A double acting ISO 21287 compact cylinder, the ACEJ63X80-20SB pairs a 63 mm bore with an 80 mm stroke that an external stop screw trims by up to 20 mm on site, giving a usable extend range of 60-80 mm. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N, rising to 2182.1 N on the extend stroke at 0.7 MPa, with a theoretical ceiling of 317.9 kgf at 1.0 MPa. The male rod thread (B code) suits couplings that need positive axial location, and the 1/8" port feeds the 16 mm hard-chrome S45C rod.
The hard-anodized aluminium body runs about 50% shorter in mounting length than an ISO 15552 profile cylinder, so it slots into presses, clamping fixtures and gantries where every millimetre of envelope counts. A fixed TPU bumper at each end absorbs end-of-stroke shock, and because the S magnet is fitted, CMSE or DMSE reed or solid-state switches can be clipped into the body slots for end-of-travel sensing. Speed range is 30-500 mm/s across 0.15-1.0 MPa (22-145 psi).

Where the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X80-20SB Is Used
Pneumatic press fixture
The 2182.1 N push at 0.7 MPa and 60-80 mm adjustable range suit a bench-top stamping or riveting head where the stroke must be trimmed to match die height without re-ordering the cylinder.
Clamping on a CNC fixture
With about 935 N of practical clamp force at 0.5 MPa and a male rod thread for direct knuckle mounting, this bore clamps aluminium housings on machining fixtures inside a tight envelope.
Gantry part present check
The fitted -S magnet accepts CMSE or DMSE switches in the body slots, so a pick-and-place gantry confirms extend position on each 80 mm cycle at up to 500 mm/s.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X80-20SB the Right Cylinder?
At this bore size the 1558.6 N push at 0.5 MPa translates to roughly 935 N of practical working force if you plan on 60% of rating, which lifts about 95 kg vertically; halve that to around 48 kg for a 2:1 margin on real part weights. If your load needs less than about 982 N at 0.5 MPa, the 50 mm bore saves space; if it needs more than 1558 N, step up to the 80 mm bore with 2513.3 N. Remember the stop screw only shortens the extend stroke - it is a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost. Mount with FA flange or LB foot on the ISO 21287 face, and confirm exact dimensions from the datasheet before cutting the fixture.
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 ACEJ63X80-20SB FAQ
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa the figures are 2182.1 N push and 2041.3 N pull, with a theoretical maximum of 317.9 kgf at 1.0 MPa. The -20 code sets a 20 mm adjustment window: an external stop screw shortens the 80 mm extend stroke by up to 20 mm, so the working range is 60-80 mm. It shortens only - it never extends past the ordered stroke and does not hold a load on air loss.
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 to absorb end-of-stroke impact. This unit carries the optional -S magnet, so CMSE or DMSE reed or solid-state switches can be mounted in the body slots. FA flange and LB foot mountings bolt to the standard face, and the B code gives a male rod thread on the 16 mm rod.
