About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X60-20
The ACEJ63X60-20 is a double acting AirTAC compact cylinder built to ISO 21287, with a 63 mm bore and a 60 mm stroke that an external stop screw trims by up to 20 mm, giving a usable extend range of 40-60 mm. At 0.5 MPa it pushes with 1558.6 N and pulls with 1458.1 N, rising to 2182.1 N at 0.7 MPa. In practice, plan on roughly 935 N of real work at 0.5 MPa, and expect it to lift about 79 kg vertically with a 2:1 margin.
The hard-anodized aluminium body with an S45C hard-chrome rod saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into presses and fixtures where a full-length body will not fit. A fixed TPU bumper at each end absorbs end-of-stroke energy, and the optional -S magnet code enables CMSE / DMSE switches; without -S there is no magnet. Ports are 1/8" PT, and the rod ends in a female M10x1.5 thread.

Where the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X60-20 Is Used
Pneumatic press fixture
The 1558.6 N push at 0.5 MPa stakes or swages aluminium terminals in an electronics assembly cell, with the 20 mm window letting the operator trim the 60 mm stroke to the die height.
Machine guard clamp
On a packaging machine, the short ISO 21287 body locks a sliding guard in tight space, lifting about 79 kg vertically with a 2:1 margin at 0.5 MPa.
Indexing table stop
A rotary indexing table uses the 40-60 mm adjustable extend range as a positive end stop, with the -S magnet option feeding a CMSE switch to the PLC for position confirmation.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X60-20 the Right Cylinder?
At this force class, bore 50 delivers 981.7 N push at 0.5 MPa and bore 80 reaches 2513.3 N, so the 63 mm bore sits between them for mid-duty clamping and lifting. If the load must stay put on air loss, add an external locking valve, because the stop screw is only an end stop and the piston will drift when pressure drops. FA flange or LB foot mounts bolt to the ISO 21287 face, and ordering the -S code adds the magnet for CMSE / DMSE 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 ACEJ63X60-20 FAQ
This 63 mm bore model pushes 1558.6 N and pulls 1458.1 N at 0.5 MPa, and 2182.1 N / 2041.3 N at 0.7 MPa, with a theoretical maximum of 317.9 kgf at 1.0 MPa. It is double acting with a 60 mm stroke adjustable down to 40 mm via the stop screw, runs on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um at 30-500 mm/s, and carries a 1/8" PT port with a female M10x1.5 rod thread.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a fixed TPU bumper at each end to absorb end-of-stroke impact. FA flange and LB foot brackets bolt straight to the standard face. Position sensing requires the optional -S magnet code, which allows CMSE / DMSE switches; the standard version without -S has no magnet fitted.
