About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X75-20S
The ACEJ63X75-20S is a double acting ISO 21287 compact cylinder with an adjustable extend stroke. Its 63 mm bore delivers 1558.6 N push and 1458.1 N pull at 0.5 MPa, rising to 2182.1 N push at 0.7 MPa. The -20 code adds a stop screw that trims the 75 mm extend stroke by up to 20 mm on site, giving a usable range of 55-75 mm without changing the cylinder.
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 gantries. A hard-anodized aluminium body runs on an S45C hard-chrome rod, with fixed TPU bumpers at both ends. This -S model carries the optional magnet, so CMSE / DMSE switches can be fitted for end-of-stroke sensing. At 0.5 MPa, plan for roughly 935 N (about 95 kg) of real work, which lifts around 79 kg vertically with a 2:1 margin.

Specifications follow the official AirTAC ACE-series (ISO 21287) datasheet. Body: hard-anodized aluminium alloy; piston rod: S45C carbon steel with hard-chrome plating. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G. A built-in magnet is OPTIONAL — add the -S code to fit CMSE / DMSE position sensors.
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 ACEJ63X75-20S Is Used
Press-fit bushing insertion
The 1558.6 N push at 0.5 MPa seats automotive bushings into housings, while the 20 mm window lets the operator trim the 75 mm stroke to match each fixture depth.
Pallet lift-and-lower station
With about 79 kg of vertical lift capacity at a 2:1 margin, the bore 63 cylinder raises small pallets on packaging lines; CMSE switches on the fitted magnet confirm top and bottom positions.
Milling fixture clamping
The short ISO 21287 body fits under machine guards where a full-length profile cylinder cannot, holding workpieces on CNC milling jigs at up to 2182.1 N push at 0.7 MPa.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X75-20S the Right Cylinder?
Size by force: bore 50 gives 981.7 N push at 0.5 MPa and bore 80 gives 2513.3 N, so the 63 mm sits between them at 1558.6 N push and 1458.1 N pull. If your fixture needs a fixed stroke rather than a trimmed one, the plain ACE63X75 covers it; the TACE twin-guide variant suits jobs needing non-rotating rods. Mounting drops onto the ISO 21287 face with FA flange or LB foot brackets plus I/Y rod knuckles. Remember the stop screw is an end stop only: on air loss the piston still drifts, so it is not a mid-stroke lock.
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 ACEJ63X75-20S FAQ
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa push rises to 2182.1 N and pull to 2041.3 N. The theoretical maximum is 317.9 kgf at 1.0 MPa. It is double acting, runs at 30-500 mm/s on 0.15-1.0 MPa (22-145 psi) air, and the stop screw trims the extend stroke anywhere in a 55-75 mm range.
An external stop screw shortens the extend stroke by up to 20 mm, so the 75 mm stroke can be set anywhere from 55 to 75 mm; it never extends past the ordered stroke. Fixed TPU bumpers absorb end-of-stroke energy at both ends. Because this model carries the -S magnet, CMSE or DMSE reed or solid-state switches mount in the body slots for end-position detection. Mounting uses FA flange or LB foot options on the standard ISO 21287 face.
