About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X45-40SB
The ACEJ63X45-40SB 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 -40 code fits an external stop screw that trims the 45 mm stroke by up to 40 mm on site, giving a usable extend range of 5-45 mm without changing the cylinder.
The hard-anodized aluminium body and S45C hard-chrome rod keep the short frame rigid, and the body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight clamping fixtures and gantries. As an -S model the magnet is already fitted, so CMSE or DMSE reed and solid-state switches can be added for end-of-stroke sensing. The B code gives a male M10x1.5 rod thread. Plan for roughly 935 N of real work at 0.5 MPa, which lifts about 79 kg vertically 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 ACEJ63X45-40SB Is Used
Clamp-and-press fixture
A 45 mm stroke with 1558.6 N push at 0.5 MPa clinches brackets or swages terminals on an assembly bench, and the -40 window lets a technician dial the stop back to 5 mm for short parts.
Gantry pick-and-place head
The short ISO 21287 body fits under low gantry beams where an ISO 15552 profile cylinder will not, and the fitted magnet with CMSE switches confirms part release at each station.
Injection mold insert eject
About 79 kg of vertical lift with a 2:1 margin ejects heavy mold inserts from a small tool, with the male M10x1.5 rod thread taking a custom ejector nose.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X45-40SB the Right Cylinder?
At 63 mm bore this sits in the mid-heavy class: step down to a 50 mm bore (981.7 N push at 0.5 MPa) for lighter presses, or up to 80 mm (2513.3 N) when the job needs more force in the same short envelope. The stop screw only shortens the extend stroke and acts as an end stop, not a mid-stroke lock, so on air loss the piston still drifts and a separate holding valve is needed for suspended loads. FA flange or LB foot mounts bolt to the ISO 21287 face, and the fitted -S magnet pairs with CMSE / DMSE switches. Runs on 0.15-1.0 MPa (22-145 psi) filtered air at 30-500 mm/s.
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 ACEJ63X45-40SB FAQ
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa those rise to 2182.1 N and 2041.3 N, with a theoretical maximum of 317.9 kgf at 1.0 MPa. The ordered stroke is 45 mm and the -40 stop screw trims the extend stroke anywhere in a 5-45 mm range. It is double acting, runs at 30-500 mm/s on 0.15-1.0 MPa (22-145 psi) air, and the bore 63 port is 1/8" PT.
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body, threaded aluminium covers and a 16 mm hard-chrome-plated S45C rod, saving about 50% of the mounting length of an ISO 15552 profile cylinder. Fixed TPU bumpers absorb end-of-stroke energy at both ends but never hold or brake a load. Because this is an -S model the magnet is already fitted, so CMSE or DMSE reed and solid-state switches mount directly in the body slots; FA flange and LB foot mounts bolt to the standard ISO 21287 face.
