About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X80-30B
A double acting ISO 21287 compact cylinder with an adjustable extend stroke, the ACEJ63X80-30B uses a 63 mm bore to deliver 1558.6 N push and 1458.1 N pull at 0.5 MPa, rising to 2182.1 N at 0.7 MPa. The B code gives a male rod thread on the 16 mm rod, and the -30 code means an external stop screw trims the 80 mm stroke on site anywhere in a 30 mm window, so the working range is 50-80 mm. Air supply is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof rating.
The short hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters in tight gantries and fixture plates. In practice, plan for roughly 935 N of real work at 0.5 MPa rather than the full rating, and for vertical duty the rod lifts about 79 kg with a 2:1 margin. A fixed TPU bumper at each end absorbs end-of-stroke shock, speed spans 30-500 mm/s, and the optional -S magnet enables CMSE / DMSE switches (this unit has no magnet fitted).

Where the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X80-30B Is Used
CNC fixture clamping
The 1558.6 N push at 0.5 MPa clamps aluminium or steel workpieces in machining fixtures, and the 50-80 mm adjustable range lets one cylinder serve several fixture heights.
Packaging line pushers
With about 935 N of practical working force, the cylinder kicks cartons or trays between conveyor lanes at 30-500 mm/s inside the short envelope a guard rail allows.
Palletizer part seating
The male rod thread (B code) suits knuckle or tool attachments that press parts about 79 kg class into nests, with the TPU bumper softening each bottom-out.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X80-30B the Right Cylinder?
At 63 mm bore this sits between the 50 mm (981.7 N push at 0.5 MPa) and the 80 mm (2513.3 N push at 0.5 MPa), so pick 63 mm when a 50 mm cylinder is marginal and 80 mm is oversized. The stop screw only shortens the extend stroke within the 30 mm window and is a mechanical end stop, not a mid-stroke lock: on air loss the piston still drifts, so add a separate valve or clamp if the load must be held. FA flange, LB foot and I/Y rod knuckles bolt to the ISO 21287 face; order the -S code if CMSE / DMSE position sensing is needed.
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 ACEJ63X80-30B FAQ
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa push is 2182.1 N and pull 2041.3 N; theoretical maximum is 317.9 kgf at 1.0 MPa. The bore is 63 mm with a 16 mm male-thread rod, 1/8" PT ports, an 80 mm stroke adjustable down to 50 mm via the -30 stop screw, operating pressure 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, and a maximum standard stroke of 250 mm for this bore.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits shallow fixtures and guarded cells. Sensing requires the optional -S magnet ordered with the cylinder; this model has no magnet, so CMSE / DMSE switches cannot be fitted unless you order the -S version. FA flange and LB foot mountings plus I/Y knuckles bolt straight to the standard face.
