About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X80-75B
The ACEJ63X80-75B is a double acting AirTAC compact cylinder built to ISO 21287, with a 63 mm bore and an 80 mm stroke that an external stop screw trims anywhere in a 75 mm window, giving a usable extend range of 5-80 mm. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa those rise to 2182.1 N and 2041.3 N, with a theoretical 317.9 kgf at 1.0 MPa. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into presses and fixtures where a full-length body will not fit.
Plan real work at roughly 935 N (about 0.6 of the push rating), which is a vertical lift of about 95 kg at 0.5 MPa, or about 47 kg with a 2:1 margin. The hard-anodized aluminium body carries a S45C hard-chrome plated 16 mm rod with a male thread (the B code), and fixed TPU bumpers absorb end-of-stroke energy at both ends. Note that no magnet is fitted on this version, so no CMSE or DMSE switch can be read unless you order the optional -S code.

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 ACEJ63X80-75B Is Used
Bench-top press station
With about 935 N of usable push at 0.5 MPa, the 63 mm bore clinches bearings and rivets in small assembly presses, and the 5-80 mm adjustable range lets one cylinder serve several part heights.
Weld fixture clamping
The short ISO 21287 body fits inside tight weld jigs where an ISO 15552 profile cylinder would overhang, and the male rod thread takes a Y knuckle for angular clamps on brackets.
Pallet gate and stopper actuation
Around 47 kg of vertical lift capacity with a 2:1 margin suits conveyor stopper blades and pallet gate arms, with the stop screw dialling the exact throw each gate needs.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X80-75B the Right Cylinder?
Size against neighbours: a 50 mm bore gives 981.7 N push at 0.5 MPa, while stepping up to 80 mm reaches 2513.3 N, so pick the 63 mm when your load sits between those classes. The stop screw only shortens the extend stroke and is a mechanical end stop, not a mid-stroke lock - on air loss the piston still drifts, so add a valve or external stop if you must hold position. FA flange and LB foot mount on the ISO 21287 face, with I and Y rod knuckles for the male-threaded rod. Ports are 1/8" PT on this bore.
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 ACEJ63X80-75B FAQ
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa, 2182.1 N push and 2041.3 N pull; theoretical maximum is 317.9 kgf at 1.0 MPa. The -75 code is a 75 mm adjustment window: an external stop screw shortens the 80 mm extend stroke on site, so the usable range is 5-80 mm. It shortens only - it never extends past the ordered stroke - and it is an end stop, not a load-holding lock. Speed range is 30-500 mm/s at 0.15-1.0 MPa (22-145 psi).
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body, S45C hard-chrome plated 16 mm rod with male thread, and fixed TPU bumpers at both ends that decelerate the piston at end of stroke. The body saves about 50% of the mounting length of an ISO 15552 profile cylinder. Sensing requires the optional -S magnet code, which allows CMSE or DMSE switches; this model has no magnet fitted, so no switch can be mounted as-is. FA flange and LB foot brackets bolt to the standard ISO 21287 face.
