About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-40B
A double acting AirTAC compact cylinder to ISO 21287, the ACEJ63X90-40B pairs a 63 mm bore with a 90 mm stroke and a male-threaded 16 mm rod. An external stop screw trims the extend stroke anywhere in the ordered 40 mm window, so one cylinder covers a 50-90 mm working range without re-plumbing. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa push rises to 2182.1 N.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters inside clamping fixtures and machine frames where depth is fixed. In practice, plan on roughly 935 N (about 95 kg) of usable push at 0.5 MPa, or expect it to lift about 79 kg vertically with a 2:1 margin. A fixed TPU bumper sits at both ends, and the optional -S magnet code enables CMSE / DMSE switch sensing.

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 ACEJ63X90-40B Is Used
CNC fixture clamping
Trims the clamp stroke from 90 mm down to 50 mm on machining fixtures where part batches change and the 1558.6 N push at 0.5 MPa seats the clamp without crushing.
Pallet lift-and-lower station
With about 79 kg of vertical lift capacity at a 2:1 margin, it raises loaded pallet plates on assembly lines; the male rod thread suits a direct platen attachment.
Case ejector on a packaging line
The 50-90 mm adjustable range matches variable carton widths, and the compact body fits the shallow frame depth a full-length profile cylinder cannot.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-40B the Right Cylinder?
At this bore size the 63 mm ACEJ sits between the 50 mm (981.7 N push at 0.5 MPa) and the 80 mm (2513.3 N push at 0.5 MPa), so step down for lighter clamps or up when the load nears the 95 kg usable figure. The stop screw is a mechanical end stop only: on air loss the piston drifts, so add a valve or lock if the position must hold. FA flange or LB foot mountings bolt to the ISO 21287 face, and the B code gives a male M16x1.5-class rod thread for direct attachment to tooling; confirm the exact rod thread from the datasheet. Order the -S variant if CMSE / DMSE switches are needed later.
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 ACEJ63X90-40B 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 is a 40 mm adjustment window: an external stop screw shortens the 90 mm extend stroke on site, giving a usable range of 50-90 mm. It shortens the stroke only and acts as an end stop, not a mid-stroke lock.
It is an ISO 21287 compact cylinder whose short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at both ends and FA flange or LB foot options. Position sensing is possible only when the optional -S magnet is ordered; this model has no magnet fitted, so CMSE / DMSE switches require the -S variant.
