About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X80-75
The ACEJ63X80-75 is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 80 mm stroke anywhere within the ordered 75 mm window, giving a usable range of 5-80 mm without changing hardware. At 0.5 MPa the 63 mm bore delivers 1558.6 N on extend and 1458.1 N on retract, rising to 2182.1 N and 2041.3 N at 0.7 MPa. In practice, plan on roughly 935 N (about 95 kg of push) for real work at 0.5 MPa rather than the full rating.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so this 63 mm unit slots into tight machine frames and gantry axes where a full-length body will not fit. A hard-anodized aluminium body runs on an S45C hard-chrome-plated 16 mm rod, with a fixed TPU bumper at each end to absorb end-of-stroke energy. Vertically, the 0.5 MPa push equals about 158 kgf, so with a 2:1 margin it lifts roughly 79 kg. Note that the stop screw is a mechanical end stop only: on air loss the piston still drifts, so it is not a load lock.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1458 N |
| 0.7 MPa | 2182 N | 2041 N |
| Max (@1.0 MPa) | 318 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X80-75 Is Used
CNC fixture clamping
Trims clamping travel between 5 and 80 mm on machining fixtures, with about 935 N of usable push at 0.5 MPa holding steel parts against hard stops.
Packaging line pushers
Short-body 63 mm pusher diverts cartons on bottling and food lines where an ISO 15552 profile cylinder is too long for the frame; 30-500 mm/s speed matches line pacing.
Pallet gate actuation
Swings pallet-line gates and guards with 1558.6 N extend force, the 75 mm adjustment window letting one cylinder serve several gate widths.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X80-75 the Right Cylinder?
Size against neighbours: a 50 mm bore gives 981.7 N push at 0.5 MPa, while stepping up to 80 mm raises it to 2513.3 N, so choose this 63 mm model when your load sits between roughly 600 and 1200 N of working force. If you need the full 80 mm stroke every cycle, the fixed-stroke ACE63X80 does the same job without the adjuster. Mounting drops onto the ISO 21287 face with FA flange or LB foot brackets plus I/Y rod knuckles. This version has no magnet; order the -S code if you later want CMSE / DMSE switch positioning.
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 ACEJ63X80-75 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 pull to 2041.3 N; theoretical maximum is 317.9 kgf at 1.0 MPa. It is double acting with an adjustable extend stroke (75 mm window on an 80 mm stroke), runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C, speed 30-500 mm/s, 1/8" port, female M10x1.5 rod thread, fixed TPU bumper both ends.
The ISO 21287 compact body saves about 50% of the mounting length of an ISO 15552 profile cylinder, and FA flange, LB foot and FTC brackets plus I/Y rod knuckles bolt straight to its face. Sensing is not included: this unit has no magnet fitted, so order the optional -S version to enable CMSE or DMSE reed or solid-state switches on the body's magnet slots.
