About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X80-40SB
The ACEJ63X80-40SB is a double acting ISO 21287 compact cylinder with a 63 mm bore and an 80 mm stroke that an external stop screw trims anywhere in a 40 mm window, giving a usable extend range of 40-80 mm. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N, rising to 2182.1 N at 0.7 MPa, with a theoretical peak of 317.9 kgf at 1.0 MPa. Because the short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, it slots into clamping fixtures and machine frames where a full-length body simply will not fit.
The S in the model code means the optional -S magnet is fitted on this unit, so CMSE or DMSE reed and solid-state switches can be slid onto the body for end-of-stroke signalling; models ordered without -S carry no magnet. The B code gives a male rod thread on the 16 mm rod, the air port is 1/8", and fixed TPU bumpers at both ends absorb end-of-stroke shock. As a rule of thumb, plan on roughly 935 N of real work at 0.5 MPa (about 0.6 of the push figure), which corresponds to lifting around 47 kg vertically - halve that to about 24 kg if you want a 2:1 margin on a vertical lift.

Where the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X80-40SB Is Used
CNC fixture clamping
The 1558.6 N push at 0.5 MPa secures aluminium housings in a machining fixture, and the 40-80 mm adjustable range lets one cylinder serve several part heights without re-plumbing.
Press-fit assembly station
Snap-fitting bearings into pump housings needs a controlled short stroke; the stop screw sets the exact extend position while the TPU bumpers soften each end of travel.
Packaging line diverters
Pushing cartons off a conveyor at 30-500 mm/s suits the 63 mm bore, and the fitted -S magnet feeds CMSE switch signals to the PLC for diverter position confirmation.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X80-40SB the Right Cylinder?
At this force class the 63 mm bore sits between the 50 mm bore (981.7 N push at 0.5 MPa) and the 80 mm bore (2513.3 N push at 0.5 MPa), so pick 63 mm when a 50 mm unit is under-rated but an 80 mm body is too bulky for the fixture. The stop screw only shortens the extend stroke within the ordered 40 mm window and acts as a mechanical end stop - it is not a mid-stroke lock, so on air loss the piston still drifts and a separate holding valve is needed for suspended loads. Mount with FA flange or LB foot brackets on the ISO 21287 face, add I or Y rod knuckles on the male thread, and keep the -S magnet in the order if CMSE / DMSE position feedback is planned.
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 ACEJ63X80-40SB FAQ
At 0.5 MPa the cylinder delivers 1558.6 N push and 1458.1 N pull; at 0.7 MPa that rises to 2182.1 N push and 2041.3 N pull, 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 80 mm extend stroke by up to 40 mm, so the working range is 40-80 mm. It shortens the stroke only - it never extends past 80 mm - and it is a mechanical end stop, not a mid-stroke lock, so the piston still drifts if air is lost.
The hard-anodized aluminium ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it fits tight guards and gantries. This unit carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be clipped anywhere along the body slots for position feedback. Mounting options include FA flange and LB foot brackets plus I and Y rod knuckles on the male-threaded 16 mm rod; the air supply is 1/8" at 0.15-1.0 MPa (22-145 psi), with fixed TPU bumpers at both ends and a speed range of 30-500 mm/s.
