About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X75-30SB
The ACEJ63X75-30SB is a double acting AirTAC compact cylinder built to ISO 21287, with a 63 mm bore and a 75 mm stroke that an external stop screw can trim anywhere in a 30 mm window, giving a usable extend range of 45-75 mm. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N, rising to 2182.1 N on the extend stroke at 0.7 MPa. The hard-anodized aluminium body with an S45C hard-chrome plated 16 mm rod runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), at speeds of 30-500 mm/s.
Because the short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, this 63 mm bore slots into tight jigs and gantries where a full-length cylinder cannot. In practice, plan for roughly 935 N (about 95 kg of force) of real work at 0.5 MPa rather than the full rating, and expect it to lift about 79 kg vertically with a 2:1 margin. The male rod thread (B code) bolts straight to I or Y rod knuckles, and the fitted -S magnet accepts CMSE / DMSE switches for end-of-stroke sensing.

Where the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X75-30SB Is Used
Clamping welded steel brackets
The 1558.6 N push at 0.5 MPa holds automotive subframe brackets in a machining fixture, with the 45-75 mm adjustable range absorbing bracket tolerance.
Short-stamp marking press
Roughly 95 kg of usable working force at 0.5 MPa is enough for date-code stamping on aluminium housings, and the compact body fits inside the press guard.
Pallet gate actuation
Lifts about 79 kg vertically with a 2:1 margin, ideal for raising safety gates on warehouse conveyor lines, with CMSE switches confirming open and closed positions.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X75-30SB the Right Cylinder?
At 63 mm bore this sits in the upper mid-force band: a 50 mm ACEJ delivers 981.7 N push at 0.5 MPa while an 80 mm bore reaches 2513.3 N, so pick the 63 mm when your clamp or press load falls between roughly 950 and 1550 N. 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 - add a separate valve or lock for load holding. FA flange or LB foot mounts bolt to the ISO 21287 face; this unit already carries the -S magnet and male rod thread, and PT ports are standard.
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 ACEJ63X75-30SB FAQ
Push is 1558.6 N and pull 1458.1 N at 0.5 MPa; at 0.7 MPa push rises to 2182.1 N. Theoretical maximum is 317.9 kgf at 1.0 MPa. It is double acting with a 75 mm stroke adjustable down to 45 mm via the -30 stop screw, runs at 30-500 mm/s on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um, and has a 16 mm male-threaded rod with 1/8" PT ports.
An external stop screw on the front cover shortens the extend stroke by up to 30 mm on site; it never lengthens the stroke past 75 mm. The fitted TPU bumper at each end absorbs end-of-stroke energy but does not hold a load. Because this model carries the optional -S magnet, CMSE or DMSE reed or solid-state switches mount directly in the body slots. FA flange and LB foot mounts bolt to the ISO 21287 face, and the short body saves about 50% of the mounting length of an ISO 15552 profile cylinder.
