About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X50-10S
The ACEJ63X50-10S is a double acting AirTAC compact cylinder built to ISO 21287, with a 63 mm bore, a 50 mm stroke and a 10 mm adjustment window. An external stop screw trims the extend stroke on site anywhere between 40 and 50 mm, so one cylinder can be tuned to several jig positions without reordering. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa those figures rise to 2182.1 N and 2041.3 N, with a theoretical maximum of 317.9 kgf at 1.0 MPa. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters in tight gantries and guarding.
In practice, plan for roughly 935 N of real work at 0.5 MPa (about 60% of the push rating), which corresponds to lifting around 95 kg vertically - and about 48 kg if you keep a 2:1 margin for a vertical lift. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be clipped onto the body slots for end-of-stroke sensing. The hard-anodized aluminium body pairs with an S45C hard-chrome-plated 16 mm rod, a female M10x1.5 rod thread, a 1/8" port, and fixed TPU bumpers at both ends. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, from -20 to +70 C.

Where the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X50-10S Is Used
Clamping fixtures on CNC machining lines
The 40-50 mm adjustable extend window lets a fixture builder dial in exact clamp position per part, while 1558.6 N at 0.5 MPa holds steel housings firmly through milling cycles.
Packaging pusher stations
A 50 mm stroke with on-site trimming to 40 mm suits carton diverters on food and beverage conveyors, and the compact body slots into the narrow space beside the belt frame.
Pallet strapping and squaring arms
With about 95 kg of vertical-lift equivalent at 0.5 MPa, the 63 mm bore squares pallet loads in end-of-line strapping machines, with CMSE switches confirming arm home position.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X50-10S the Right Cylinder?
At 63 mm bore this sits in the mid-heavy class: 1558.6 N push at 0.5 MPa. If your load needs under about 980 N, the 50 mm bore (981.7 N push at 0.5 MPa) is the smaller step; if you need over 2180 N, step up to the 80 mm bore (2513.3 N push at 0.5 MPa). Remember the stop screw is a mechanical end stop for the extend stroke only - it does not lock the piston mid-stroke, and on air loss the rod will drift, so add a separate holding valve if the load must stay put. Bolt on FA flange or LB foot mounts plus I/Y rod knuckles to the standard ISO 21287 face, and order CMSE or DMSE switches to suit the -S magnet fitted here.
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 ACEJ63X50-10S 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; the theoretical maximum is 317.9 kgf at 1.0 MPa. The -10 code is a 10 mm adjustment window: an external stop screw shortens the 50 mm extend stroke by up to 10 mm, giving a usable range of 40-50 mm. It shortens the stroke only - it never extends it past 50 mm, and it is a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost. Speed range is 30-500 mm/s and operating pressure is 0.15-1.0 MPa (22-145 psi).
It is an ISO 21287 compact cylinder whose short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits shallow machine frames and guarded cells. Both ends carry fixed TPU bumpers that absorb end-of-stroke impact. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be mounted in the body slots for position feedback. FA flange and LB foot mounts plus I/Y rod knuckles bolt straight to the ISO 21287 face, and the rod end is a female M10x1.5 thread with a 1/8" air port.
