About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X80-50B
A double acting ISO 21287 compact cylinder, the ACEJ63X80-50B pairs a 63 mm bore with an 80 mm stroke and a male rod thread (B code) on its 16 mm hard-chrome plated S45C rod. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N, rising to 2182.1 N push at 0.7 MPa, with a theoretical peak of 317.9 kgf at 1.0 MPa. The -50 code adds an external stop screw that trims the extend stroke anywhere in a 50 mm window, giving a usable range of 30-80 mm without swapping the cylinder.
The short ISO 21287 body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight machine frames and gantries. Plan on about 935 N of real work at 0.5 MPa (roughly 60% of the push rating), which corresponds to lifting about 79 kg vertically with a 2:1 margin. Air supply is 0.15-1.0 MPa (22-145 psi) filtered to 40 um, speed runs 30-500 mm/s, and fixed TPU bumpers at both ends absorb end-of-stroke shock. Note that this unit has no magnet fitted; order the -S version if you need CMSE / DMSE switch sensing.

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 ACEJ63X80-50B Is Used
Press-fit bushing insertion
The 1558.6 N push at 0.5 MPa presses bearings and bushings into gearbox housings, while the 50 mm window lets you dial the stroke down to 30 mm for shallow press depths.
Pallet gate actuation
Lifts about 79 kg vertically with margin, enough to raise pallet-line gate arms and diverters on a warehouse conveyor without a larger bore.
Fixture clamping on machining centers
Clamps turbine-blade jigs inside guarded CNC cells where the compact body, about 50% shorter than an ISO 15552 profile cylinder, is the only unit that fits.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X80-50B the Right Cylinder?
At this bore size the ACEJ63X80-50B sits in the mid-heavy class: a 50 mm bore delivers 981.7 N push at 0.5 MPa, while stepping up to 80 mm raises it to 2513.3 N. If your clamping or pressing load sits near 935 N of usable force, this 63 mm model is the right fit. The stop screw only shortens the extend stroke and acts as an end stop, not a mid-stroke lock, so the rod will still drift if air is lost. Mounting choices include FA flange and LB foot plus I/Y rod knuckles on the ISO 21287 face; PT ports are standard and G threads are available. Add the -S code if position feedback via CMSE / DMSE switches 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 ACEJ63X80-50B FAQ
Push is 1558.6 N and pull 1458.1 N at 0.5 MPa; at 0.7 MPa push reaches 2182.1 N and pull 2041.3 N, with a theoretical maximum of 317.9 kgf at 1.0 MPa. The 63 mm bore has a 16 mm rod, 1/8" PT ports, an 80 mm stroke adjustable down to 30 mm via the -50 stop screw, operating pressure 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and a temperature range of -20 to +70 C.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body, threaded aluminium covers, and a hard-chrome plated S45C rod, with fixed TPU bumpers at both ends that absorb end-of-stroke energy. FA flange, LB foot and I/Y knuckles bolt to the standard ISO 21287 face. Switch sensing is not included on this model because it has no magnet; order the -S variant to enable CMSE / DMSE reed or solid-state switches.
