About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X55-10B
The ACEJ63X55-10B 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 10 mm, giving a usable extend range of 45-55 mm. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa those figures rise to 2182.1 N and 2041.3 N, with a theoretical maximum of 317.9 kgf at 1.0 MPa. The male rod thread (B code) on the 16 mm rod bolts directly to tooling.
The short hard-anodized aluminium body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight clamping fixtures and machine frames. 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, or roughly 40 kg with a 2:1 margin. A fixed TPU bumper absorbs end-of-stroke shock at both ends, and the optional -S magnet enables CMSE / DMSE switches when ordered.

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 ACEJ63X55-10B Is Used
Press-fit clamping of aluminium housings
The 1558.6 N push at 0.5 MPa seats bearing sleeves in gearbox housings, and the 45-55 mm adjustable window lets one cylinder serve two housing depths.
Pallet-stacker lift assist
With about 79 kg of vertical lift equivalent at 0.5 MPa, the 63 mm bore raises fork-mounted trays in compact warehouse gates too short for a profile cylinder.
Bottling-line reject pusher
Running at 30-500 mm/s on 1/8" ports, the short body clears guard rails while the stop screw trims the stroke to match lane width exactly.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X55-10B the Right Cylinder?
Size between neighbours: the 50 mm bore delivers 981.7 N push at 0.5 MPa while the 80 mm bore reaches 2513.3 N, so the 63 mm bore at 1558.6 N sits squarely in the mid-heavy clamping and lifting class. If you need to hold a load through an air-loss event, note the stop screw is a mechanical end stop only, not a mid-stroke lock. Mount with FA flange or LB foot on the ISO 21287 face, add I or Y rod knuckles for the male thread, and order the -S code if CMSE / DMSE position sensing is required.
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 ACEJ63X55-10B 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. 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, fluid air filtered to 40 um. The 55 mm stroke is adjustable down to 45 mm via the stop screw, the rod is 16 mm with a male thread, and the port is 1/8".
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, S45C hard-chrome rod and fixed TPU bumpers at both ends. Sensing is available only when you order the optional -S magnet code, which then accepts CMSE / DMSE switches; this model without the S code carries no magnet.
