About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X60-40B
The ACEJ63X60-40B is a double acting ISO 21287 compact cylinder with an adjustable extend stroke. Its 63 mm bore delivers 1558.6 N push and 1458.1 N pull at 0.5 MPa, rising to 2182.1 N at 0.7 MPa, with a theoretical maximum of 317.9 kgf at 1.0 MPa. The male-threaded 16 mm rod (the B code) bolts directly to tooling without an adapter nut.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into cramped clamping fixtures and machine frames. A stop screw trims the extend stroke on site by up to 40 mm, giving a usable range of 20-60 mm. In practice, plan for roughly 935 N of real work at 0.5 MPa, which lifts about 79 kg vertically with a 2:1 margin. FA flange, LB foot and I/Y rod knuckles mount on the standard face, and the optional -S magnet enables CMSE / DMSE switches.

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 ACEJ63X60-40B Is Used
Clamp fixture actuation
Trim the extend stroke from 60 down to 20 mm to match part heights in welding and machining jigs, using the 1558.6 N push at 0.5 MPa to hold steel workpieces against locators.
Pallet gate and stopper lift
The short body fits under conveyor frames where a full-length profile cylinder will not; about 79 kg vertical lift with a 2:1 margin covers most gate and stopper weights.
Case ejection on packaging lines
Male-threaded rod drives ejector paddles at 30-500 mm/s, and the 40 mm adjustment window lets one cylinder serve multiple carton sizes without swapping hardware.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X60-40B the Right Cylinder?
Size by force: the 50 mm bore gives 981.7 N push at 0.5 MPa, while the 80 mm bore reaches 2513.3 N, so the 63 mm sits squarely between them for medium-duty clamping and pressing. Remember the stop screw is a mechanical end stop, not a mid-stroke lock - on air loss the rod still drifts, so add a separate holding valve for suspended loads. If you need position sensing, order the -S variant; this model has no magnet fitted. Ports are 1/8" PT, and strokes up to 250 mm are standard for this bore.
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 ACEJ63X60-40B FAQ
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa that rises to 2182.1 N push and 2041.3 N pull, with a theoretical maximum of 317.9 kgf at 1.0 MPa. It 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, with a fixed TPU bumper at both ends and a 1/8" PT port.
The -40 code sets a 40 mm adjustment window: an external stop screw shortens the 60 mm extend stroke on site, giving a usable range of 20-60 mm - it cannot lengthen the stroke past 60 mm. The hard-anodized aluminium body carries magnet slots, but sensors need the optional -S magnet code; this model has none fitted, so order ACEJ63X60-40BS if you plan to use CMSE / DMSE switches. FA flange, LB foot and I/Y knuckles mount on the ISO 21287 face.
