About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X70-50
A double acting ISO 21287 compact cylinder, the ACEJ63X70-50 pairs a 63 mm bore with a 70 mm stroke that an external stop screw trims anywhere in a 50 mm window, giving a usable extend range of 20-70 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 tight gantries and guarding where a full-length body cannot.
For real-world sizing, plan on roughly 935 N of usable push at 0.5 MPa (about 0.6 of the rating), which is enough to lift about 79 kg vertically with a 2:1 margin. The hard-anodized aluminium body carries a roller-burnished bore, the S45C rod is hard-chrome plated, and fixed TPU bumpers absorb end-of-stroke energy. Air supply is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, and the rod ends in a female M10x1.5 thread with 1/8" ports.

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 ACEJ63X70-50 Is Used
Press-fit bushing insertion
The 1558.6 N push at 0.5 MPa seats bearings and bushings in gearbox housings, and the 50 mm window lets one cylinder serve several housing depths on the same fixture.
Pallet lift-and-lower station
With about 79 kg of vertical lift capacity at a 2:1 margin, it raises small pallets or tote stacks on a packaging line, retracting fully within the 70 mm stroke.
Weld-cell part clamping
The short ISO 21287 body fits inside tight weld fixtures where an ISO 15552 profile cylinder would not, clamping brackets against a locating pin at up to 2182.1 N at 0.7 MPa.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X70-50 the Right Cylinder?
At this force class the 63 mm bore sits between the 50 mm (981.7 N push at 0.5 MPa) and the 80 mm (2513.3 N push at 0.5 MPa); pick 50 mm for lighter clamping, 80 mm when the load approaches 1500 N. The stop screw only shortens the extend stroke and is a mechanical end stop, not a mid-stroke lock, so the rod will drift if air is lost. Mounting bolts straight onto the ISO 21287 face: FA flange, LB foot or FTC bracket, with I/Y rod knuckles. If position feedback is needed, order the -S variant so CMSE / DMSE switches can be fitted; this model has 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 ACEJ63X70-50 FAQ
Push is 1558.6 N and pull 1458.1 N at 0.5 MPa; 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 70 mm extend stroke to any value from 20 mm up, so one cylinder covers multiple product sizes. 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.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, S45C hard-chrome rod and fixed TPU bumpers at both ends. FA flange, LB foot and FTC brackets plus I and Y rod knuckles bolt to the standard face. Position sensing requires the optional -S magnet, which enables CMSE / DMSE switches; this model without the S code has no magnet, so no sensor can be mounted.
