About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X55-30S
The ACEJ63X55-30S is a double acting ISO 21287 compact cylinder with an adjustable extend stroke. Air drives the piston both ways, a fixed TPU bumper decelerates at each end, and an external stop screw trims the 55 mm stroke by up to 30 mm, giving a usable extend range of 25-55 mm. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa that rises to 2182.1 N push. The hard-anodized aluminium body with roller-burnished bore and an S45C hard-chrome plated 16 mm rod stands up to continuous jig and gantry duty.
Because the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, this 63 mm bore slots into tight guarding and slide assemblies where a full-length body will not fit. Plan on roughly 935 N (about 95 kg) of real work at 0.5 MPa, which lifts around 79 kg vertically with a 2:1 margin. The fitted -S magnet accepts CMSE / DMSE reed or solid-state switches anywhere along the body slots, and FA flange or LB foot mounts bolt straight to the ISO 21287 face.

Where the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X55-30S Is Used
Weld fixture clamping
The 1558.6 N push at 0.5 MPa clamps steel brackets in automotive weld jigs, and the 25-55 mm adjustable window lets one cylinder serve different part heights without re-plumbing.
Pallet press-down station
On packaging line palletizing heads, the 63 mm bore seats cartons or lids with about 95 kg of usable force, while CMSE switches via the fitted magnet confirm full seat position.
Conveyor gate diverter
Short-stroke pusher gates on bottling conveyors use the compact body behind tight guarding, with the stop screw trimming throw to match lane widths on site.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X55-30S the Right Cylinder?
Size against the load: the next bore down, 50 mm, delivers 981.7 N push at 0.5 MPa, while the 80 mm bore reaches 2513.3 N. If your clamping or pressing load sits between those figures, the 63 mm bore with its 1558.6 N push is the efficient pick. Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock, so the rod will still drift if air is lost. Order FA or LB mounting to suit the fixture and note this unit already carries the -S magnet for CMSE / DMSE switching; air supply should be filtered to 40 um at 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s.
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 ACEJ63X55-30S FAQ
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa push is 2182.1 N and pull 2041.3 N; theoretical maximum is 317.9 kgf at 1.0 MPa. The -30 code sets a 30 mm adjustment window: an external stop screw shortens the 55 mm extend stroke by up to 30 mm, so the working range is 25-55 mm. It is a mechanical end stop only and does not hold a load on air loss. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, port 1/8" PT, female rod thread M10x1.5.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits shallow fixtures and guarded slides. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches clip into the body slots for end-of-stroke or mid-range signals. FA flange and LB foot mounts bolt to the standard ISO 21287 face, and a fixed TPU bumper at both ends absorbs end-of-stroke impact.
