About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X80-50
A double acting ISO 21287 compact cylinder, the ACEJ63X80-50 pairs a 63 mm bore with an 80 mm stroke that an external stop screw can trim on site by up to 50 mm, giving a usable extend range of 30-80 mm. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N, rising to 2182.1 N at 0.7 MPa. In practice, plan on roughly 935 N (about 95 kgf) of real work at 0.5 MPa instead of the full rating, which keeps clamping and pressing cycles comfortably inside the cylinder's capability.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight fixtures and guarded cells. Vertically, the 0.5 MPa push equals about 159 kgf, so halve that for a 2:1 margin and it lifts about 79 kg. The hard-anodized aluminium body carries a 16 mm S45C hard-chrome rod, fixed TPU bumpers sit at both ends, and FA flange or LB foot mounts plus I/Y rod knuckles bolt straight to the ISO 21287 face. Speed range is 30-500 mm/s over 0.15-1.0 MPa (22-145 psi).

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 ACEJ63X80-50 Is Used
Press-fit bushing insertion
The 1558.6 N push at 0.5 MPa seats automotive bushings in aluminium housings, with the 30-80 mm adjustable range matching varying part heights on one fixture.
Pallet clamp on a machining line
Clamps CNC pallets with about 935 N of usable force at 0.5 MPa; the short ISO 21287 body fits under low fixture plates where a full-length profile cylinder cannot.
Small part lift-and-lower station
Lifts about 79 kg die-cast parts vertically with a 2:1 margin, with the stop screw trimming the extend stroke to the exact transfer height.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X80-50 the Right Cylinder?
At this bore size the 63 mm unit delivers 1558.6 N push at 0.5 MPa; step down to a 50 mm bore (981.7 N) for lighter clamps or up to an 80 mm bore (2513.3 N) when the load grows. The stop screw only shortens the extend stroke and is a mechanical end stop, not a mid-stroke lock, so the rod can still drift if air is lost. Choose the female M10x1.5 rod thread as coded here, add FA or LB mounting to suit the fixture, and if position feedback is ever needed, order the -S variant so CMSE / DMSE switches can be fitted; without -S there is no magnet.
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 ACEJ63X80-50 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, with a theoretical maximum of 317.9 kgf at 1.0 MPa. The -50 code is a 50 mm adjustment window: an external stop screw shortens the 80 mm extend stroke by up to 50 mm, so the usable range is 30-80 mm. It is a mechanical end stop only and does not hold a load if air pressure is lost.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, 16 mm hard-chrome rod and fixed TPU bumpers at both ends. FA flange, LB foot mounts and I/Y rod knuckles attach directly to the standard face. Position sensing requires the optional -S magnet code, which allows CMSE / DMSE switches; this model without -S carries no magnet, so no switch can be mounted.
