About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X75-40S
The ACEJ63X75-40S is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 75 mm stroke by up to 40 mm, giving a usable range of 35-75 mm on site. At 0.5 MPa the 63 mm bore pushes 1558.6 N and pulls 1458.1 N, rising to 2182.1 N at 0.7 MPa. In practice, plan on roughly 935 N (about 95 kg of force) of 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 it slots into tight fixtures where a full-length body will not fit. The hard-anodized aluminium body carries an S45C hard-chrome rod, a fixed TPU bumper at each end, and the fitted -S magnet accepts CMSE / DMSE switches for end-position sensing. Vertically, the 1558.6 N push equates to about 159 kg, so with a 2:1 margin it lifts roughly 79 kg.

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 ACEJ63X75-40S Is Used
CNC fixture clamping
Clamps steel brackets on a machining centre fixture, where the 35-75 mm adjustable range handles different part heights without swapping cylinders.
Case press-down station
Presses carton flaps on a packaging line at about 935 N usable force at 0.5 MPa, with CMSE switches confirming the pressed position.
Pallet gate actuation
Swings heavy pallet-line gates where the compact body fits the guard space and the 79 kg vertical-lift margin covers the gate weight.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X75-40S the Right Cylinder?
At 63 mm bore this sits in the mid-heavy class: 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. If your jig needs less than about 935 N of usable force, the 50 mm bore saves cost; if you are near the limit, go 80 mm. The 40 mm window suits stations where the same cylinder serves several product widths. Remember the stop screw is a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost. FA flange, LB foot, FTC brackets and I/Y rod knuckles bolt to the ISO 21287 face, and the fitted -S magnet lets CMSE / DMSE switches report end positions.
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 ACEJ63X75-40S 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, with a theoretical maximum of 317.9 kgf at 1.0 MPa. The -40 code sets a 40 mm adjustment window: a stop screw shortens the 75 mm extend stroke to any value from 35 to 75 mm. It is a mechanical end stop only and does not hold a load if air pressure is lost.
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 16 mm rod and a fixed TPU bumper at both ends. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be clipped on for end-position signals. FA flange, LB foot, FTC brackets and I/Y rod knuckles mount directly; the rod end is female M10x1.5 and the port is 1/8" PT. Operating range is 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s.
