About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-75B
The ACEJ63X90-75B 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 peak of 317.9 kgf at 1.0 MPa. The B code gives a male 16 mm rod end, and the 1/8" port serves this bore size. As a rule of thumb, plan on roughly 935 N (about 95 kg equivalent) 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 presses and gantries where a full-length body will not fit. A stop screw trims the 90 mm extend stroke anywhere within the ordered 75 mm window, giving a usable range of 15-90 mm on site. Fixed TPU bumpers absorb end-of-stroke shock at both ends, and the hard-anodized aluminium body with an S45C hard-chrome rod stands up to continuous cycling at 30-500 mm/s.

Specifications follow the official AirTAC ACE-series (ISO 21287) datasheet. Body: hard-anodized aluminium alloy; piston rod: S45C carbon steel with hard-chrome plating. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G. A built-in magnet is OPTIONAL — add the -S code to fit CMSE / DMSE position sensors.
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 ACEJ63X90-75B Is Used
Bench-top crimping press
With 1558.6 N push at 0.5 MPa and a stroke trimmed down to 15 mm via the 75 mm window, this cylinder suits compact crimping and staking fixtures on electronics assembly benches.
Gantry pick-and-place clamp
The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, letting the 63 mm bore clamp heavy automotive brackets under low-clearance gantry beams.
Packaging machine ejector
Running at 30-500 mm/s with fixed TPU bumpers at both ends, the adjustable 15-90 mm extend stroke ejects cartons or trays on food and beverage lines without hammering the frame.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-75B the Right Cylinder?
Size this model when your jig needs roughly 1550 N of push at 0.5 MPa. A 50 mm bore gives 981.7 N at the same pressure, while an 80 mm bore reaches 2513.3 N, so the 63 mm sits squarely in the mid-heavy class. Remember the stop screw is a mechanical end stop only: on air loss the piston still drifts, so it is not a load-holding lock. FA flange or LB foot mounts bolt to the ISO 21287 face, and if you need position feedback, order the -S variant so CMSE / DMSE switches can be fitted - this unit ships without a magnet.
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 ACEJ63X90-75B FAQ
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa it pushes 2182.1 N and pulls 2041.3 N, with a theoretical maximum of 317.9 kgf at 1.0 MPa. The -75 code sets a 75 mm adjustment window: an external stop screw shortens the 90 mm extend stroke by up to 75 mm, so the working range is 15-90 mm. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), and speed 30-500 mm/s. It is double acting with a male rod thread (B code) and a 1/8" port.
The ISO 21287 short-body design saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body and an S45C hard-chrome-plated 16 mm rod. Fixed TPU bumpers at both ends absorb end-of-stroke energy. FA flange, LB foot and FTC brackets plus I and Y rod knuckles bolt straight to the standard face. This model has no magnet fitted; order the -S code to enable CMSE / DMSE reed or solid-state switches for end-position sensing.
