About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X75-75B
The ACEJ63X75-75B is a double acting ISO 21287 compact cylinder with a 63 mm bore and a 75 mm stroke that an external stop screw trims anywhere in the 0-75 mm range. 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 peak of 317.9 kgf at 1.0 MPa. The male rod thread (B code) bolts straight into standard tooling.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight welding jigs and press frames. A rule of thumb: plan on roughly 936 N (about 95 kg) of usable push at 0.5 MPa, which lifts about 79 kg vertically - halve that for a 2:1 margin on real part weight. FA flange, LB foot and I/Y knuckles mount on the ISO 21287 face; the optional -S magnet enables CMSE / DMSE switches, and this code ships without it.

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 ACEJ63X75-75B Is Used
Welding fixture clamping
The 1558.6 N push at 0.5 MPa clamps steel brackets in automotive weld cells, and the 0-75 mm trim lets one cylinder serve multiple part heights.
Small press and forming station
With 2182.1 N available at 0.7 MPa, the 63 mm bore handles light staking and marking on aluminium housings where a full-length profile cylinder will not fit.
Pallet eject on packaging lines
About 79 kg of vertical lift equivalent at 0.5 MPa ejects loaded carton trays from a conveyor lane; the compact body mounts under low guard rails.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X75-75B the Right Cylinder?
Size up if 1558.6 N at 0.5 MPa is marginal: the 80 mm bore delivers 2513.3 N push and 2356.2 N pull at the same pressure. Size down to the 50 mm bore (981.7 N push) when the load is lighter and panel space is tight. 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. Order the -S suffix if you need CMSE / DMSE position sensing; PT ports and FA/LB mounting suit most standard 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 ACEJ63X75-75B FAQ
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa, 2182.1 N push and 2041.3 N pull; theoretical maximum is 317.9 kgf at 1.0 MPa. The -75 code is a 75 mm adjustment window: an external stop screw shortens the 75 mm extend stroke on site anywhere from 0 to 75 mm. It never lengthens the stroke past the ordered 75 mm, and it is an end stop only - it does not hold a load if air pressure drops. Operating pressure is 0.15-1.0 MPa (22-145 psi) and speed is 30-500 mm/s.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, S45C hard-chrome plated 16 mm rod and a fixed TPU bumper at each end to absorb end-of-stroke shock. FA flange and LB foot mounts plus I/Y rod knuckles bolt to the standard face. Position sensing needs the optional -S magnet code - this model has no magnet fitted, so order ACEJ63X75-75BS if you want CMSE / DMSE switches to work.
