About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X75-30B
The ACEJ63X75-30B is a double acting ISO 21287 compact cylinder with a 63 mm bore and a 75 mm stroke that an external stop screw trims on site. The -30 code gives a 30 mm adjustment window, so the extend stroke can be set anywhere from 45 mm to the full 75 mm without changing the cylinder. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N, and the male rod thread (B code) bolts straight to tooling.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight clamping fixtures and guarded machines. In practice, plan for roughly 935 N of real work at 0.5 MPa, which is about 95 kg - and it lifts around 79 kg vertically with a 2:1 margin. A fixed TPU bumper at each end absorbs end-of-stroke energy, and the hard-anodized aluminium body with an S45C hard-chrome 16 mm rod runs at 30-500 mm/s on air filtered to 40 um.

Where the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X75-30B Is Used
Clamping on CNC fixtures
The 45-75 mm adjustable extend stroke lets one cylinder serve several fixture heights, with 1558.6 N of push holding aluminium or steel workpieces during milling.
Pallet gate actuation
Around 79 kg of vertical lift capacity with a 2:1 margin suits raising and lowering pallet-line stop gates and diverters at 30-500 mm/s.
Baling and press-fit stations
The 63 mm bore's 2182.1 N push at 0.7 MPa handles light press-fit and compaction jobs where the short body must fit inside a machine frame.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X75-30B the Right Cylinder?
At 0.5 MPa this bore delivers 1558.6 N push and 1458.1 N pull. If your load needs under about 1374 N, the 50 mm bore (981.7 N push) is the smaller step; if you need over 2182 N, step up to the 80 mm bore (2513.3 N push). Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock - on air loss the piston still drifts, so add a separate holding valve for suspended loads.
Mount FA flange or LB foot plates plus I/Y rod knuckles on the standard ISO 21287 face. This unit has no magnet fitted; if you need position sensing, order the -S version to enable CMSE / DMSE switches. Port is 1/8" PT, and the maximum standard stroke for bore 63 is 250 mm.
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 ACEJ63X75-30B 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; the 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 75 mm extend stroke by up to 30 mm, giving a usable range of 45-75 mm. It cannot lengthen the stroke past 75 mm, and the stop is not a load-holding brake - on air loss the piston still drifts.
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 both ends. FA flange and LB foot mounts plus I/Y rod knuckles bolt to the standard face. This model has no magnet; order the optional -S code to enable CMSE / DMSE switches. Operating range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C, and the rod end is male thread with a 1/8" PT port.
