Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-75
The AirTAC Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-75 is a genuine double acting, adjustable stroke ISO 21287 compact air cylinder with a Ø63mm bore and 90mm stroke, 1/8" air ports and a hard-anodized aluminium body.

About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-75
A double acting ISO 21287 compact cylinder with an adjustable extend stroke, the ACEJ63X90-75 pairs a 63 mm bore with a 90 mm stroke and a 75 mm trim window. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N, rising to 2182.1 N on the extend side at 0.7 MPa, with a theoretical ceiling of 317.9 kgf at 1.0 MPa. The external stop screw shortens the extend stroke anywhere in the ordered 75 mm window, so one cylinder covers a usable 15-90 mm range without re-plumbing.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it slots into press fixtures and gantries where a full-length body cannot. Rule of thumb for sizing: plan on roughly 935 N of real work at 0.5 MPa (about 0.6 of the push figure), which vertically lifts about 95 kg with a 2:1 margin. A fixed TPU bumper at each end absorbs end-of-stroke energy, and FA flange or LB foot mounts bolt straight to the ISO 21287 face.

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 ACEJ63X90-75 Is Used
Pneumatic press fixture
The 1558.6 N push at 0.5 MPa suits riveting and staking heads on aluminium brackets, and the 75 mm window lets one cylinder serve several die heights between 15 and 90 mm.
Palletizer part lift
Lifts about 95 kg vertically with a 2:1 margin, enough for trays of filled bottles or castings on a packaging line, with the LB foot mount anchoring it under the lift plate.
CNC fixture clamping
Clamps machined housings in a tight machining-centre fixture where the compact body, roughly half the length of an ISO 15552 profile cylinder, clears the enclosure wall.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-75 the Right Cylinder?
At 1558.6 N push at 0.5 MPa this 63 mm bore sits between the 50 mm bore (981.7 N) and the 80 mm bore (2513.3 N), so step down for lighter clamping or up for heavy lift-and-press work. Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock: on air loss the piston still drifts, so add a separate holding valve if the load must stay put. Order the -S code if you need the optional magnet for CMSE / DMSE switches; this non-S unit has no magnet fitted. Female M10x1.5 rod thread and PT ports come standard, with FA and LB mounting available.
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 ACEJ63X90-75 FAQ
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa push rises to 2182.1 N, and the theoretical maximum is 317.9 kgf at 1.0 MPa. It is double acting with a 90 mm stroke trimmed by a 75 mm stop-screw window (usable 15-90 mm), runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, with a 16 mm hard-chrome rod, M10x1.5 female rod thread and 1/8" ports.
An external stop screw mechanically shortens the extend stroke by up to 75 mm, so you set any extend position from 15 to 90 mm on site; it never lengthens the stroke past 90 mm. Fixed TPU bumpers at both ends absorb the impact at each end of travel. The hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, FA flange and LB foot mounts bolt to the standard ISO 21287 face, and the optional -S magnet enables CMSE / DMSE position switches (not fitted on this model).
