About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X55-50B
The ACEJ63X55-50B is a double acting, adjustable-stroke compact cylinder built to the ISO 21287 short-body format. Its 63 mm bore delivers 1558.6 N in push and 1458.1 N in pull at 0.5 MPa, rising to 2182.1 N at 0.7 MPa, with a theoretical ceiling of 317.9 kgf at 1.0 MPa. The hard-anodized aluminium body carries a 16 mm S45C hard-chrome-plated rod, and the male rod thread (the B code) bolts straight into standard tooling. As a rule of thumb, plan on roughly 935 N of usable work at 0.5 MPa, which is about 95 kg of vertical lift with a 2:1 margin - enough to raise a loaded pallet clamp or a heavy welding fixture.
The -50 code gives a 50 mm adjustment window: an external stop screw trims the 55 mm extend stroke down to as little as 5 mm on site, so one cylinder covers several product sizes without re-plumbing. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, freeing space in tight gantries and guards. Fixed TPU bumpers absorb end-of-stroke shock at both ends, speed runs 30-500 mm/s, and the optional -S magnet enables CMSE / DMSE switches (this unit has no magnet fitted).

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1458 N |
| 0.7 MPa | 2182 N | 2041 N |
| Max (@1.0 MPa) | 318 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X55-50B Is Used
Welding fixture clamping
The 1558.6 N push at 0.5 MPa seats heavy steel weldments into locating pins, and the 5-55 mm adjustable range handles different bracket heights on one jig.
Pallet gate actuation on packaging lines
With about 95 kg of vertical lift capability at a 2:1 margin, the cylinder swings or lifts heavy diverters on palletizing conveyors within a compact frame.
Press-fit of bushings in machine assembly
The 63 mm bore gives mid-range pressing force for bearings and bushings into housings, with the stop screw setting exact insertion depth per part revision.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X55-50B the Right Cylinder?
At 63 mm bore this sits in the mid-heavy class: the 50 mm bore pushes 981.7 N at 0.5 MPa and the 80 mm bore reaches 2513.3 N, so choose down or up from 1558.6 N depending on your fixture load. Remember the stop screw is a mechanical end stop only - on air loss the piston still drifts, so add a separate locking solution if the load must be held. FA flange or LB foot mountings 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 ACEJ63X55-50B FAQ
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 -50 code means an external stop screw can shorten the 55 mm extend stroke by up to 50 mm, giving a usable range of 5-55 mm. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C, speed 30-500 mm/s, with a fixed TPU bumper at both ends and a 1/8" PT port.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits where a full-length profile cylinder cannot. FA flange and LB foot mounts plus I and Y rod knuckles bolt directly to the standard face. Sensing requires the optional -S magnet ordered with the cylinder; this model has no magnet, so CMSE / DMSE switches cannot be fitted unless you order the -S variant.
