About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X75-50SB
The ACEJ63X75-50SB is a double acting ISO 21287 compact cylinder with a 63 mm bore and a 75 mm stroke that an external stop screw trims on site: the -50 code gives a 50 mm adjustment window, so the extend stroke is set anywhere between 25 and 75 mm. 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 maximum of 317.9 kgf at 1.0 MPa. The male rod thread (B code) bolts straight to tooling, and the 1/8" port is fixed by the bore size.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight gantries and guarded stations. Because the stop screw is a mechanical end stop only, the piston still drifts if air is lost, so it is not a load lock. As a rule of thumb, plan on roughly 935 N of real work at 0.5 MPa, which lifts about 95 kg vertically with margin. The -S magnet is fitted on this model, so CMSE / DMSE switches can be mounted in the body slots.

Where the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X75-50SB Is Used
CNC fixture clamping
Trims its extend stroke between 25 and 75 mm to clamp varying aluminium forgings on a machining centre fixture, using about 935 N of usable force at 0.5 MPa.
Packaging line pusher
Pushes cartons off a conveyor at a guarded transfer point where the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder.
Pallet stamping station
Drives a code stamp into pallet blocks with 1558.6 N at 0.5 MPa, the male rod thread picking up the stamp head directly.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X75-50SB the Right Cylinder?
At 1558.6 N push at 0.5 MPa, the 63 mm bore sits between the 50 mm bore (981.7 N) and the 80 mm bore (2513.3 N); step up to 80 mm if your jig needs over 1500 N of continuous work, or down to 50 mm for lighter clamping. The 75 mm stroke is well inside the 250 mm maximum standard stroke for this bore, so no made-to-order length is needed. Choose FA flange or LB foot mounting to match the ISO 21287 face, and remember the stop screw shortens the extend stroke only - it never holds position against air loss. This unit carries the -S magnet and a male rod thread on a PT port thread.
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 ACEJ63X75-50SB FAQ
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa push is 2182.1 N and pull 2041.3 N; theoretical maximum is 317.9 kgf at 1.0 MPa. The -50 stop screw shortens the 75 mm extend stroke by up to 50 mm, giving a usable 25-75 mm range. It is a mechanical end stop, not a mid-stroke lock, so the rod still drifts on air loss. Operating pressure is 0.15-1.0 MPa (22-145 psi) and speed is 30-500 mm/s.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, S45C hard-chrome rod and fixed TPU bumpers at both ends. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches mount in the body slots for end-of-stroke detection. FA flange and LB foot mountings bolt to the standard face, and the 1/8" port is set by the 63 mm bore.
