About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X70-10
A double acting ISO 21287 compact cylinder with an adjustable extend stroke, the ACEJ63X70-10 pairs a 63 mm bore with a 70 mm stroke and a 10 mm trim window. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N, 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 S45C hard-chrome plated 16 mm rod, and a fixed TPU bumper sits at each end.
Because the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, it slots into tight clamping stations and gantry frames. In practice, plan on roughly 935 N of real work at 0.5 MPa (about 0.6 of the push rating), which lifts around 95 kg vertically - halve that for a 2:1 margin and match parts up to about 47 kg. FA flange, LB foot and I/Y rod knuckles bolt straight to the ISO 21287 face.

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 ACEJ63X70-10 Is Used
CNC fixture clamping
The 1558.6 N push at 0.5 MPa secures aluminium housings in machining fixtures, and the 10 mm trim lets you dial the clamp point between 60 and 70 mm without shims.
Packaging line pushers
With a 70 mm stroke and speeds of 30-500 mm/s, the short body ejects cartons or trays on conveyor transfers where a full-length profile cylinder will not fit.
Assembly press stations
About 935 N of usable work force at 0.5 MPa suits light press-fit and staking operations on small electromechanical assemblies.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X70-10 the Right Cylinder?
At this force class the 63 mm bore 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) for heavy presses. The -10 stop screw trims the extend stroke anywhere in a 60-70 mm window on site - it is a mechanical end stop only, so the piston still drifts if air is lost and it never holds a load mid-stroke. Order the -S code if you need the optional magnet for CMSE / DMSE switches; this unit has no magnet fitted. Ports are 1/8" and the rod end is female M10x1.5.
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 ACEJ63X70-10 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 theoretical maximum force is 317.9 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, air filtered to 40 um. The extend stroke is adjustable within a 10 mm window (60-70 mm usable), and the maximum standard stroke for this bore is 250 mm.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body, threaded aluminium covers, a 16 mm S45C hard-chrome rod and fixed TPU bumpers at both ends - roughly 50% shorter in mounting length than an ISO 15552 profile cylinder. Sensing requires the optional -S magnet code; with it, CMSE / DMSE switches mount in the body slots. This model (no S code) has no magnet, so no switch can be read. FA flange, LB foot and I/Y knuckles fit the standard ISO 21287 face.
