About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X70-30
A double acting ISO 21287 compact cylinder with an adjustable extend stroke, the ACEJ63X70-30 pairs a 63 mm bore with a 70 mm stroke and a 30 mm adjustment window. An external stop screw trims the extend stroke on site anywhere from 40 mm to 70 mm, so one cylinder serves several jig positions. 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 short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which makes it easy to fit into tight clamping fixtures and machine guards. In practice, plan on roughly 935 N (about 95 kg) of usable push force at 0.5 MPa, or lift about 79 kg vertically with a 2:1 margin. The hard-anodized aluminium body carries an S45C hard-chrome-plated rod, a fixed TPU bumper sits at both ends, and FA flange or LB foot mounts bolt straight to the standard face. Speed range is 30-500 mm/s across 0.15-1.0 MPa (22-145 psi) of clean, 40 um filtered air.

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 ACEJ63X70-30 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 mm window letting one cylinder cover several housing depths.
Pallet clamp on a machining line
Clamps aluminium gearbox housings on a CNC fixture; the short body fits inside the guard where a full-length ISO 15552 profile cylinder would not.
Parts-ejector on a stamping die
Ejects stamped brackets off the die face at up to 500 mm/s, lifting parts of about 79 kg vertically with a 2:1 safety margin.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X70-30 the Right Cylinder?
Size against the load: a 50 mm bore gives 981.7 N push at 0.5 MPa, while the next size up, an 80 mm bore, delivers 2513.3 N. This 63 mm model at 1558.6 N push suits mid-range clamping and pressing where the 70 mm stroke can be trimmed down to 40 mm by the stop screw. Remember the adjuster is a mechanical end stop only - on air loss the piston still drifts, so it is not a load-holding brake. FA flange and LB foot mountings plus I/Y rod knuckles fit the ISO 21287 face. This version has no magnet; order the -S code if you need CMSE or DMSE switch position sensing.
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 ACEJ63X70-30 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, with a theoretical maximum of 317.9 kgf at 1.0 MPa. The -30 code is a 30 mm adjustment window: an external stop screw shortens the 70 mm extend stroke by up to 30 mm, giving a usable range of 40-70 mm. It is a mechanical end stop, not a mid-stroke lock - 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 to absorb end-of-stroke energy. This version has no magnet fitted; order the -S code to enable CMSE or DMSE reed or solid-state switches. Mounting options include FA flange and LB foot, and the 1/8" port suits bores 32-63.
