About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X80-40
The ACEJ63X80-40 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, giving a usable range of 40-80 mm on site. At 0.5 MPa the 63 mm bore delivers 1558.6 N push and 1458.1 N pull, rising to 2182.1 N push at 0.7 MPa, with a theoretical ceiling of 317.9 kgf at 1.0 MPa. The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight gantries and fixtures.
Plan on roughly 935 N of real work at 0.5 MPa (about 0.6 of the push rating), which corresponds to lifting about 79 kg vertically with a 2:1 margin. The hard-anodized aluminium body carries an S45C hard-chrome rod, a fixed TPU bumper sits at both ends, and speed runs 30-500 mm/s at 0.15-1.0 MPa (22-145 psi). Note this unit has no -S code, so no magnet is fitted and no CMSE / DMSE switch can be read from it.

Where the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X80-40 Is Used
Fixture clamping on CNC pallets
The 1558.6 N push at 0.5 MPa clamps aluminium housings in machining fixtures, and the 40-80 mm adjustable window absorbs fixture height variations without re-plumbing.
Case ejection on packaging lines
Pushing filled cartons off a conveyor lane needs about 935 N of usable force; the compact body fits where a full-length profile cylinder would not.
Bench press for small assemblies
A light press station pressing bushings into brackets uses the 2182.1 N push at 0.7 MPa, with the stop screw set to a repeatable 40-80 mm stroke.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X80-40 the Right Cylinder?
Size both ways: the 50 mm bore gives 981.7 N push at 0.5 MPa, while the 80 mm bore steps up to 2513.3 N, so the 63 mm at 1558.6 N sits in the middle for medium clamping and pressing. If you need to hold a load mid-stroke on air loss, remember the stop screw is a mechanical end stop only, not a lock. FA flange or LB foot mounts bolt to the ISO 21287 face; add the -S code at order time if you later want CMSE / DMSE switch sensing.
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 ACEJ63X80-40 FAQ
Push is 1558.6 N and pull 1458.1 N at 0.5 MPa; 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 63 mm bore has a 16 mm rod, a 1/8" PT port, a female M10x1.5 rod thread, an 80 mm stroke adjustable down to 40 mm via the stop screw, speed 30-500 mm/s, and operating pressure 0.15-1.0 MPa (22-145 psi).
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at each end and FA flange or LB foot mounting. Sensing is only possible on the optional -S version, which carries the magnet for CMSE / DMSE switches; this model has no -S code, so no magnet is fitted.
