About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X50-30SB
The ACEJ63X50-30SB is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 50 mm stroke by up to 30 mm, giving a usable range of 20-50 mm without changing the order code. At 0.5 MPa the 63 mm bore delivers 1558.6 N on extend and 1458.1 N on retract, rising to 2182.1 N at 0.7 MPa, so it carries mid-size clamping and pressing work in a body that saves about 50% of the mounting length of an ISO 15552 profile cylinder.
For sizing, plan on roughly 935 N (about 95 kg) of real work at 0.5 MPa rather than the full rating, which corresponds to lifting about 79 kg vertically with a 2:1 margin. The male rod thread (B code) suits external rod accessories, the fitted -S magnet accepts CMSE / DMSE switches for end-position sensing, and FA flange or LB foot mounts bolt straight onto the ISO 21287 face.

Specifications follow the official AirTAC ACE-series (ISO 21287) datasheet. Body: hard-anodized aluminium alloy; piston rod: S45C carbon steel with hard-chrome plating. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G. A built-in magnet is OPTIONAL — add the -S code to fit CMSE / DMSE position sensors.
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 ACEJ63X50-30SB Is Used
Press-fit of bearing sleeves
The 1558.6 N extend force at 0.5 MPa presses bushings into pump housings, while the 20-50 mm adjustable window lets the operator dial in the exact seating depth per part.
Fixture clamping on CNC pallets
The short ISO 21287 body fits under low fixture guards where a full-length profile cylinder will not, and the male rod thread takes knuckle links for swing clamps.
Gated ejection on packaging lines
With the fitted -S magnet driving CMSE switches, the PLC confirms the 50 mm eject stroke completed before the conveyor index releases the next carton.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X50-30SB the Right Cylinder?
Choose this model when a 63 mm bore is right but the exact stroke will be set on the machine: the stop screw shortens the extend stroke anywhere in the 20-50 mm window. If you need less force, a 50 mm bore gives 981.7 N push at 0.5 MPa; if you need more, an 80 mm bore reaches 2513.3 N. 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. PT ports, male rod thread, and FA/LB mounting cover standard fixtures; the fitted -S magnet enables CMSE / DMSE position switches.
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 ACEJ63X50-30SB 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; theoretical maximum is 317.9 kgf at 1.0 MPa. The -30 code sets a 30 mm adjustment window: an external stop screw shortens the 50 mm extend stroke by up to 30 mm, so the working range is 20-50 mm. It runs double acting on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, with a fixed TPU bumper at both ends.
It is an ISO 21287 compact cylinder whose hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight gantries and jigs. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be clipped into the body slots for end-position signals. FA flange and LB foot mounts bolt to the standard ISO 21287 face, and the male rod thread accepts I or Y rod knuckles.
