About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X80-40B
The ACEJ63X80-40B is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 80 mm stroke by up to 40 mm on site, giving a usable range of 40-80 mm without swapping the cylinder. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N, rising to 2182.1 N at 0.7 MPa, so it handles heavy clamping and pressing work in a body that saves about 50% of the mounting length of an ISO 15552 profile cylinder.
The 16 mm hard-chrome-plated S45C rod ends in a MALE thread (the B code), handy when your fixture takes a stud-end fitting. A practical sizing note: 0.6 of the push force gives roughly 935 N of real work at 0.5 MPa, which lifts about 95 kg vertically - halve that for a 2:1 margin on a vertical lift. Fixed TPU bumpers absorb end-of-stroke shock, the hard-anodized aluminium body resists wear, and the optional -S magnet enables CMSE / DMSE switches (no magnet is fitted on this code).

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 ACEJ63X80-40B Is Used
Press-fit bushing insertion
The 1558.6 N push at 0.5 MPa seats automotive bushings and bearings in housings, with the 40 mm window letting one cylinder serve several housing depths on the same fixture.
Heavy pallet clamp on a machining line
Clamps cast-iron pallets on CNC fixtures; the short ISO 21287 body fits inside the guard envelope where a full-length profile cylinder would not.
Vertical lift-and-lower gantry station
Lifts about 95 kg of tooling vertically at 0.5 MPa with margin to spare, and the male rod thread bolts directly to stud-end lift plates.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X80-40B the Right Cylinder?
At this bore size the step either way is significant: a 50 mm bore delivers 981.7 N push at 0.5 MPa, while an 80 mm bore reaches 2513.3 N - pick the 63 mm when your load sits between roughly 600 and 950 N working force. 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. Mounting drops straight onto the ISO 21287 face with FA flange or LB foot options plus I/Y rod knuckles; if you need position feedback, order the -S variant so CMSE / DMSE switches can be fitted.
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 ACEJ63X80-40B 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 sets a 40 mm adjustment window: an external stop screw shortens the 80 mm extend stroke anywhere down to 40 mm, so the usable range is 40-80 mm. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C.
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 hard-anodized aluminium body, S45C hard-chrome rod and fixed TPU bumpers at both ends. This code has no magnet fitted; the optional -S magnet allows CMSE / DMSE switches to be mounted for end-position sensing. FA flange and LB foot mountings plus I/Y rod knuckles bolt to the standard ISO 21287 face, and the B code gives a male rod thread with a 1/8" port.
