About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-50B
A double acting ISO 21287 compact cylinder, the ACEJ63X90-50B pairs a 63 mm bore with a 90 mm stroke that an external stop screw trims anywhere in a 50 mm window, giving a usable extend range of 40-90 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 ceiling of 317.9 kgf at 1.0 MPa. The male rod thread (B code) on the 16 mm rod bolts straight into knuckle fittings.
The short hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into gantries and welding fixtures where a full-length body cannot. Plan on roughly 935 N of real work at 0.5 MPa, which lifts about 79 kg vertically with a 2:1 margin. A fixed TPU bumper at each end absorbs end-of-stroke shock, and the optional -S magnet enables CMSE / DMSE switches; without it no sensor can be fitted.

Where the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-50B Is Used
Welding fixture clamping
The 1558.6 N push at 0.5 MPa clamps steel brackets in automotive weld cells, and the 40-90 mm trim range adapts one cylinder to different part heights.
Pallet elevator stops
Lifts about 79 kg vertically with a 2:1 margin, suiting small pallet or tote lift stations in packaging lines where headroom is tight.
Press assist on short strokes
Delivers 2182.1 N at 0.7 MPa for light press-fit and staking jobs on electronics assemblies, with the male rod thread taking knuckle tooling directly.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X90-50B the Right Cylinder?
Step down to an ACEJ50 (981.7 N push at 0.5 MPa) for lighter clamping, or up to an ACEJ80 (2513.3 N) when the load grows. Remember the stop screw only shortens the extend stroke and drifts on air loss, so add a separate lock for load holding. FA flange or LB foot mounts and I/Y rod knuckles fit the ISO 21287 face; order the -S code if CMSE / DMSE position sensing is needed.
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 ACEJ63X90-50B 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 the theoretical maximum is 317.9 kgf at 1.0 MPa. The -50 code sets a 50 mm adjustment window: an external stop screw shortens the 90 mm extend stroke on site, so the working range is 40-90 mm. It cannot lengthen the stroke past 90 mm, and the stop is not a load-holding brake.
The hard-anodized aluminium body is an ISO 21287 compact build that saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at both ends. Position sensing needs the optional -S magnet, which allows CMSE / DMSE switches; this model has no magnet, so no sensor can be mounted. FA flange, LB foot, FTC brackets and I/Y rod knuckles bolt to the standard face, and the 1/8" PT ports run on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um at 30-500 mm/s.
