About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X60-40SB
A double acting ISO 21287 compact cylinder, the ACEJ63X60-40SB pairs a 63 mm bore with a 60 mm stroke and a 40 mm adjustment window: an external stop screw on the front cover lets you trim the extend stroke anywhere between 20 and 60 mm on site, no disassembly needed. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N, rising to 2182.1 N at 0.7 MPa, with a theoretical ceiling 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, so it slots into tight welding jigs and machine frames a full-length body cannot reach. The hard-anodized aluminium barrel carries a hard-chrome plated S45C rod with a male thread (B code), and because this model carries the optional -S magnet you can clip CMSE or DMSE switches straight onto the body for end-of-stroke sensing. A practical rule of thumb: plan for roughly 0.6 of the push force, about 935 N, and at 0.5 MPa that translates to lifting around 79 kg vertically, or about 40 kg with a 2:1 margin.

Where the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X60-40SB Is Used
Clamping welded brackets
The 1558.6 N push at 0.5 MPa holds steel brackets firmly in a welding fixture, and the 20-60 mm adjustable window lets one cylinder serve several bracket sizes.
Short-stroke press station
With 2182.1 N available at 0.7 MPa, this bore handles light press-fitting of bushings and bearings where a full-length profile cylinder would not fit the frame.
Packaging line diverters
The compact body plus CMSE switch feedback from the fitted -S magnet makes it a clean choice for pusher arms on bottling and carton divert stations.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X60-40SB the Right Cylinder?
Size against neighbours: a 50 mm bore gives 981.7 N push at 0.5 MPa, while stepping up to 80 mm buys 2513.3 N. If your press or clamp load sits between those, the 63 mm bore with its 1558.6 N push is the efficient middle choice. Remember the stop screw is a mechanical end stop for the extend stroke only - on air loss the piston still drifts, so add a separate valve or lock if the load must be held. FA flange and LB foot mountings bolt to the ISO 21287 face, and the -S magnet in this model works with CMSE / DMSE switches. Runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 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 ACEJ63X60-40SB FAQ
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa that rises to 2182.1 N push and 2041.3 N pull, with a theoretical maximum of 317.9 kgf at 1.0 MPa. The -40 code is a 40 mm adjustment window: an external stop screw shortens the 60 mm extend stroke by up to 40 mm, giving a usable range of 20-60 mm. It shortens the stroke only - it never extends it past 60 mm, and it is an end stop, not a mid-stroke lock.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits shallow jigs and guarded machines. A fixed TPU bumper at each end absorbs end-of-stroke impact. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches mount directly on the body slots. FA flange and LB foot mountings plus I and Y rod knuckles bolt to the standard ISO 21287 face, and the male-threaded rod (B code) suits clevis-style tooling.
