About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X80-50SB
A double acting ISO 21287 compact cylinder with an adjustable extend stroke, the ACEJ63X80-50SB pairs a 63 mm bore with an 80 mm stroke that an external stop screw trims by up to 50 mm, giving a usable range of 30-80 mm on site. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N, rising to 2182.1 N at 0.7 MPa, with a theoretical ceiling of 317.9 kgf at 1.0 MPa. The male rod thread (B code) and the fitted -S magnet make it ready for CMSE / DMSE switch mounting straight out of the box.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight clamping fixtures and guarded gantries. A hard-anodized aluminium body carries an S45C hard-chrome rod, a fixed TPU bumper sits at both ends, and the 1/8" port feeds speeds of 30-500 mm/s across 0.15-1.0 MPa (22-145 psi). As a rule of thumb, plan on roughly 935 N (about 95 kg) of real vertical work at 0.5 MPa, which means this bore lifts about 79 kg vertically even with a 2:1 margin.

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 ACEJ63X80-50SB Is Used
Press-fit bushing insertion
The 1558.6 N push at 0.5 MPa seats automotive bushings into control-arm housings, with the 30-80 mm adjustable range tuned per fixture.
Pallet clamp on a CNC fixture
Roughly 95 kg of usable vertical force at 0.5 MPa clamps machined pallets firmly, and the short body fits inside the fixture footprint.
Case ejector on a packing line
The 80 mm stroke, trimmed down by the stop screw, kicks filled cartons off a conveyor lane at up to 500 mm/s, with CMSE switches confirming eject.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X80-50SB the Right Cylinder?
Size against neighbours: the 50 mm bore delivers 981.7 N push at 0.5 MPa, while stepping up to 80 mm gives 2513.3 N, so the 63 mm bore sits squarely in the mid-force band for clamping and pressing. 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 valve or lock for load holding. FA flange, LB foot and FTC brackets plus I/Y rod knuckles bolt to the ISO 21287 face; the -S magnet on this model lets CMSE / DMSE switches report end positions.
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 ACEJ63X80-50SB 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, with a theoretical maximum of 317.9 kgf at 1.0 MPa. The -50 code gives a 50 mm adjustment window, so the extend stroke can be trimmed anywhere between 30 and 80 mm with the external stop screw. Operating pressure is 0.15-1.0 MPa (22-145 psi) and speed runs 30-500 mm/s.
It is an ISO 21287 compact cylinder - about 50% shorter in mounting length than an ISO 15552 profile cylinder - with a hard-anodized aluminium body, S45C hard-chrome rod, threaded covers and a fixed TPU bumper at each end. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be clipped into the body slots to signal extend and retract positions. FA flange, LB foot and FTC brackets mount on the standard face.
