About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X55-30B
The ACEJ63X55-30B is a double acting AirTAC compact cylinder built to ISO 21287, with a 63 mm bore and a 55 mm stroke that an external stop screw trims by up to 30 mm on site, giving a usable extend range of 25-55 mm. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N, rising to 2182.1 N at 0.7 MPa. The hard-anodized aluminium body with an S45C hard-chrome plated 16 mm rod runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s.
Because the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, this 63 mm bore drops into tight clamping fixtures and gantry frames that a full-length cylinder cannot reach. In practice, plan on roughly 935 N of usable push at 0.5 MPa, which lifts about 79 kg vertically with a 2:1 margin. The male (B) rod thread and PT ports suit direct tooling attachment, and FA flange or LB foot mounts bolt to the standard 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 ACEJ63X55-30B Is Used
Press-fit clamping fixture
The 1558.6 N push at 0.5 MPa seats bearing sleeves into aluminium housings on a small assembly cell, with the 30 mm window letting the setter dial the 55 mm stroke down to match each part family.
Gantry pick-and-place stop
Mounted under a gantry frame where length is limited, the compact body positions a stop plate for cartons on a packaging line, lifting about 79 kg vertically with margin.
Mould changeover clamp
On an injection mould tool, the male rod thread bolts straight to a clamp arm and the 25-55 mm adjustable range accommodates different mould heights without swapping cylinders.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X55-30B the Right Cylinder?
Size between the 50 mm bore (981.7 N push at 0.5 MPa) and the 80 mm bore (2513.3 N push at 0.5 MPa) when 63 mm output is more than the job needs. The 55 mm stroke with a 30 mm trim window covers fixture variations without re-ordering; the stop screw is a mechanical end stop only, so on air loss the piston drifts and it must not be relied on to hold a load. This unit has no magnet fitted - order the -S code if CMSE / DMSE switch position sensing is needed later.
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 ACEJ63X55-30B 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 55 mm extend stroke by up to 30 mm, so the working range is 25-55 mm. It is double acting, runs 30-500 mm/s on 0.15-1.0 MPa (22-145 psi) air, and the stroke trim is an end stop, not a load-holding brake.
It is an ISO 21287 compact cylinder: hard-anodized aluminium body, S45C hard-chrome plated 16 mm rod, threaded aluminium covers, 1/8" PT ports and a fixed TPU bumper at both ends that absorbs end-of-stroke energy. The body is about 50% shorter in mounting length than an ISO 15552 profile cylinder. This unit has no magnet, so no CMSE / DMSE switch can be read - order the -S version to enable sensing. FA flange and LB foot mounts fit the standard face.
