About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X30-30B
The ACEJ63X30-30B 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 at 0.7 MPa, with a theoretical peak of 317.9 kgf at 1.0 MPa. The male-threaded rod (B code) is 16 mm S45C steel with hard-chrome plating, running in a hard-anodized aluminium body.
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 machine frames. For sizing, plan on roughly 935 N of real work at 0.5 MPa (about 60% of the push rating), which lifts about 79 kg vertically with a 2:1 margin. The -30 stop screw trims the 30 mm extend stroke anywhere in a 0-30 mm window; fixed TPU bumpers absorb end-of-stroke shock at both ends. Note: no magnet is fitted on this version, so position switches cannot be used unless you order the optional -S magnet code.

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 ACEJ63X30-30B Is Used
Clamping of machined housings
The 1558.6 N push at 0.5 MPa clamps aluminium gearbox housings in a CNC fixture, with the 0-30 mm trim letting one cylinder serve different part heights.
Short-stroke press station
A bench-top marking or staking press uses the 30 mm stroke and about 79 kg vertical lift equivalent to seat bushings in small pump bodies.
Gate pusher on a compact line
Tight gantry spacing on a packaging line accepts the short ISO 21287 body where a full-length profile cylinder would not fit, pushing totes between stops.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X30-30B the Right Cylinder?
At 63 mm bore this sits in the mid-heavy force class: 1558.6 N push at 0.5 MPa versus 981.7 N for a 50 mm bore and 2513.3 N for an 80 mm bore, so step down or up depending on your clamp or press load. The stop screw is a mechanical end stop for the extend stroke only - on air loss the piston still drifts, so do not rely on it to hold a load mid-stroke. Mounting: FA flange or LB foot bolt to the ISO 21287 face, with I/Y rod knuckles for the male thread. If you need CMSE or DMSE switch feedback, order the -S variant instead, since this unit has no magnet.
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 ACEJ63X30-30B 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; theoretical maximum is 317.9 kgf at 1.0 MPa. The -30 code gives a 30 mm adjustment window: an external stop screw shortens the 30 mm extend stroke to any value from 0 to 30 mm. It runs double acting on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, with a 1/8" PT port and a 16 mm male-thread rod.
The hard-anodized aluminium ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with fixed TPU bumpers at both ends absorbing end-of-stroke shock. FA flange and LB foot mounts plus I/Y rod knuckles bolt straight to the standard face. This version has no magnet, so CMSE or DMSE switches only work if you order the optional -S magnet code; the stroke is also available up to 250 mm standard on this bore.
