About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X45-10S
The ACEJ63X45-10S is a double acting ISO 21287 compact cylinder with an adjustable extend stroke. Its 63 mm bore delivers 1558.6 N push and 1458.1 N pull at 0.5 MPa, rising to 2182.1 N at 0.7 MPa, with a theoretical peak of 317.9 kgf at 1.0 MPa. The -10 code adds a 10 mm adjustment window: an external stop screw trims the 45 mm extend stroke on site to any length from 35 to 45 mm, so one cylinder serves several fixture positions. A fixed TPU bumper at each end absorbs end-of-stroke shock.
The hard-anodized aluminium body with an S45C hard-chrome plated 16 mm rod keeps the short ISO 21287 footprint, saving about 50% of the mounting length of an ISO 15552 profile cylinder - useful in tight jig plates and gantry frames. The fitted -S magnet lets CMSE or DMSE reed or solid-state switches report end positions. As a rule of thumb, plan on roughly 935 N (about 95 kg) of real working force at 0.5 MPa, which corresponds to lifting a part of about 79 kg vertically with a 2:1 margin.

Where the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X45-10S Is Used
Fixture clamping on CNC machining centres
The 1558.6 N push at 0.5 MPa clamps aluminium or cast-iron workpieces in dedicated jigs, and the 35-45 mm adjustable window absorbs fixture tolerance without re-plumbing.
Press-fit and staking stations
About 935 N of usable working force at 0.5 MPa suits light staking and snap-fit assembly of automotive clips and connector housings, with CMSE switches confirming each cycle via the fitted magnet.
Short-stroke part ejection from stamping dies
The 45 mm stroke clears thin stamped parts from die nests, and the compact body fits where an ISO 15552 profile cylinder would be about twice as long.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X45-10S the Right Cylinder?
Size against neighbours: the 50 mm bore gives 981.7 N push at 0.5 MPa, while the 80 mm bore reaches 2513.3 N - this 63 mm model sits between them at 1558.6 N push and 1458.1 N pull. If the job needs a longer travel than 45 mm, remember the stop screw only shortens stroke within the 10 mm window; it never extends beyond the ordered stroke. The adjuster is a mechanical end stop, not a mid-stroke lock, so the piston can still drift if air is lost - do not use it to hold a load. FA flange and LB foot mountings bolt to the ISO 21287 face, and the fitted magnet pairs with CMSE / DMSE switches for position feedback. Speed range is 30-500 mm/s at 0.15-1.0 MPa (22-145 psi).
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 ACEJ63X45-10S FAQ
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa it pushes 2182.1 N and pulls 2041.3 N; theoretical maximum is 317.9 kgf at 1.0 MPa. The bore is 63 mm with a 16 mm rod, the ordered stroke is 45 mm, and the -10 stop screw trims the extend stroke by up to 10 mm for a usable 35-45 mm range. It runs at 30-500 mm/s on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um, with a 1/8" PT port and a female M10x1.5 rod thread.
It is an ISO 21287 compact cylinder: a hard-anodized aluminium body with a hard-chrome plated S45C rod, about 50% shorter in mounting length than an ISO 15552 profile cylinder, with a fixed TPU bumper at each end that only decelerates the piston near the ends of travel. FA flange and LB foot mountings fit the standard ISO 21287 face. This model carries the optional -S magnet, so CMSE or DMSE reed or solid-state switches can be clamped into the body slots for end-position feedback.
