About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X50-30S
The ACEJ63X50-30S is a double acting ISO 21287 compact cylinder with a 63 mm bore and a 50 mm stroke that an external stop screw trims on site: the -30 code gives a 30 mm adjustment window, so the extend stroke can be set anywhere from 20 to 50 mm without changing the cylinder. At 0.5 MPa it pushes with 1558.6 N and pulls with 1458.1 N, rising to 2182.1 N on the extend stroke at 0.7 MPa, with a theoretical maximum of 317.9 kgf at 1.0 MPa.
Its short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight gantries and guarding where a full-length body cannot fit. As a rule of thumb, plan for roughly 935 N of real work at 0.5 MPa (about 0.6 of the push force), which is the equivalent of lifting around 95 kg vertically with a 2:1 margin. The -S magnet is fitted on this model, so CMSE / DMSE reed or solid-state switches can be mounted directly in the body slots, and FA flange or LB foot mounts plus I/Y rod knuckles bolt to the standard ISO 21287 face.

Where the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X50-30S Is Used
Weld fixture clamping
The 1558.6 N push at 0.5 MPa holds steel brackets against locating pins in automotive weld jigs, while the 20-50 mm trimmed stroke clears for part loading and clamps in one setting.
Pallet elevator stops
With roughly 95 kg of vertical lift capacity at a 2:1 margin, the cylinder raises and lowers small pallet platforms on packaging lines, and the fitted magnet feeds CMSE switches for up/down confirmation.
Conveyor diverters
On bottling lines the 50 mm stroke (trimmable to 20 mm) pushes cartons between lanes at 30-500 mm/s, and the compact body slots under guard rails where an ISO 15552 profile cylinder would be too long.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X50-30S the Right Cylinder?
At 63 mm bore this sits in the mid-heavy class: step down to a 50 mm bore (981.7 N push at 0.5 MPa) for lighter clamping, or up to an 80 mm bore (2513.3 N) when the load grows. Remember the stop screw is a mechanical end stop for the extend stroke only - it is not a mid-stroke lock, so on air loss the piston can still drift and a separate holding valve is needed for suspended loads. If the trimmed stroke range of 20-50 mm does not match the job, order a different -NN window (10/20/30/40/50/75/100 mm); FA flange or LB foot mounting and the female M10x1.5 rod thread drop into standard fixtures.
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 ACEJ63X50-30S 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 -30 code is a 30 mm adjustment window: an external stop screw shortens the 50 mm extend stroke on site, giving a usable range of 20-50 mm. It shortens the stroke only - it never extends it past 50 mm, and it is an end stop, not a mid-stroke lock.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body and S45C hard-chrome plated 16 mm rod, saving about 50% of the mounting length of an ISO 15552 profile cylinder. Fixed TPU bumpers at both ends absorb end-of-stroke energy, the air port is 1/8" (PT), and the rod end carries a female M10x1.5 thread. FA flange and LB foot mounts plus I/Y rod knuckles bolt to the standard face, and because the -S magnet is fitted on this model, CMSE / DMSE switches can be clipped into the body slots for position sensing.
