About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X75-40
The ACEJ63X75-40 is a double acting ISO 21287 compact cylinder with a 63 mm bore and a 75 mm stroke that an external stop screw can trim on site by up to 40 mm, giving a usable extend range of 35-75 mm. 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 hard-anodized aluminium body and S45C hard-chrome plated rod run on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, from -20 to +70 C.
Because the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, it slots into tight weld fixtures and gantry clamps where a full-length body will not reach. For vertical work, halve the push force for a 2:1 margin: it lifts about 79 kg safely, or plan on roughly 935 N of real work at 0.5 MPa. Fixed TPU bumpers absorb end-of-stroke shock at both ends, and FA flange or LB foot mounts plus I/Y rod knuckles bolt straight to the ISO 21287 face. This unit has no magnet; order the -S code if you need CMSE / DMSE switch sensing.

Where the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X75-40 Is Used
Weld fixture clamping
The 1558.6 N push at 0.5 MPa clamps steel brackets in automotive weld jigs, while the 40 mm window lets technicians dial the clamp gap from 35 to 75 mm without swapping cylinders.
Small press and forming station
With 2182.1 N available at 0.7 MPa, the 63 mm bore handles light staking, marking and snap-fit pressing on electronics assembly lines, and the compact body fits shallow press frames.
Pallet lift-and-lower gate
Lifting about 79 kg vertically with margin, the cylinder raises pallet stops or gate arms in warehouse conveyor systems; the -S magnet option adds CMSE / DMSE end-position sensing.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X75-40 the Right Cylinder?
At 63 mm this sits in the mid-heavy class: the 40 mm bore pushes 628.3 N at 0.5 MPa and the 80 mm bore pushes 2513.3 N, so choose this size when your clamp or press needs roughly 1.5 kN. Remember the stop screw only shortens the extend stroke and drifts on air loss, so add a separate lock for load holding. If you need position feedback, order the -S variant; this code ships without a magnet. Female M10x1.5 rod thread and PT ports suit standard fittings; FA, LB and FTC mounts drop into existing fixtures.
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 ACEJ63X75-40 FAQ
Push is 1558.6 N and pull 1458.1 N at 0.5 MPa; at 0.7 MPa push rises to 2182.1 N, and theoretical maximum is 317.9 kgf at 1.0 MPa. The 63 mm bore drives a 16 mm rod through 1/8" PT ports. Operating range is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C. The stop screw trims the extend stroke anywhere in a 40 mm window, so the effective range is 35-75 mm. Max standard stroke for this bore is 250 mm.
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. FA flange, LB foot and FTC brackets plus I and Y rod knuckles bolt to the standard face. Sensors need the optional -S magnet code: this model has no magnet fitted, so order ACEJ63X75-40S to run CMSE or DMSE switches. The rod ends in a female M10x1.5 thread, and fixed TPU bumpers at both ends soften stroke ends.
