About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X45-30SB
The ACEJ63X45-30SB is a double acting ISO 21287 compact cylinder with an adjustable extend stroke. Its 63 mm bore delivers 1558.6 N push and 1458.1 N pull at 0.5 MPa, rising to 2182.1 N push at 0.7 MPa, with a theoretical peak of 317.9 kgf at 1.0 MPa. An external stop screw trims the 45 mm stroke by up to 30 mm on site, giving a usable extend range of 15-45 mm without changing the cylinder.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight presses and gantries. In practice, plan for roughly 936 N (about 95 kg) of real work at 0.5 MPa, which corresponds to lifting around 79 kg vertically with a 2:1 margin. The hard-anodized aluminium body carries an S45C hard-chrome 16 mm rod, a fixed TPU bumper sits at both ends, and the -S magnet fitted to this model accepts CMSE / DMSE switches.

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 ACEJ63X45-30SB Is Used
Bench-top crimping press
A 63 mm bore pushing 1558.6 N at 0.5 MPa crimps terminals and small brackets; the 15-45 mm adjustable window lets the operator set the exact crimp depth per die.
Fixture clamping on a machining line
Clamps aluminium housings before milling with about 936 N of usable force at 0.5 MPa; the short ISO 21287 body fits inside the fixture envelope where a full-length profile cylinder cannot.
Position-verified ejection on a packaging line
The fitted -S magnet drives CMSE / DMSE switches so the PLC confirms each 45 mm eject stroke; speed runs 30-500 mm/s to match line rate.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X45-30SB the Right Cylinder?
At 63 mm bore this sits in the mid-heavy class: a 50 mm bore gives 981.7 N push at 0.5 MPa, while an 80 mm bore raises it to 2513.3 N. Choose this model when 1558.6 N at 0.5 MPa covers the job but the stroke must be set precisely between 15 and 45 mm. Note the stop screw is a mechanical end stop only - on air loss the piston still drifts, so it is not a mid-stroke lock. FA flange or LB foot mountings bolt to the ISO 21287 face, and the male rod thread (B code) suits external knuckles; PT ports are standard and G is available.
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 ACEJ63X45-30SB FAQ
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa it pushes 2182.1 N and pulls 2041.3 N; theoretical maximum is 317.9 kgf at 1.0 MPa. The -30 code is a 30 mm adjustment window: an external stop screw shortens the 45 mm extend stroke by up to 30 mm, so the usable range is 15-45 mm. It shortens the stroke only and acts as an end stop, not a load-holding brake.
It is an ISO 21287 compact cylinder whose short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at each end. FA flange and LB foot mountings plus I and Y rod knuckles bolt to the standard face. This -S version carries the optional magnet, so CMSE / DMSE reed or solid-state switches can be fitted; without the -S code there is no magnet. Operating range is 0.15-1.0 MPa (22-145 psi), air filtered to 40 um, -20 to +70 C, speed 30-500 mm/s, 1/8" PT ports.
