About the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X60-50B
The ACEJ63X60-50B is a double acting ISO 21287 compact cylinder with a 63 mm bore and a 60 mm stroke that can be trimmed on site by up to 50 mm, giving a usable extend range of 10-60 mm. An external stop screw sets the shorter stroke without swapping parts, and a fixed TPU bumper at each end absorbs end-of-stroke energy. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N, so as a rule of thumb plan on roughly 935 N (about 95 kg) of real working force rather than the full rating.
The hard-anodized aluminium body with an S45C hard-chrome plated 16 mm rod saves about 50% of the mounting length of an ISO 15552 profile cylinder, which makes this bore size practical inside press fixtures and weld jigs where a full-length body will not fit. The male (B code) rod thread suits external rod accessories, and the 1/8" port keeps plumbing simple. Note that this unit has no magnet fitted: order the optional -S code if you need CMSE or DMSE switch sensing.

Where the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X60-50B Is Used
Weld fixture clamping
Trimming the 60 mm stroke down to 10-30 mm lets one cylinder clamp varying sheet thicknesses on automotive weld jigs, with 1558.6 N of push at 0.5 MPa holding parts firmly.
Machining-center part ejection
The short ISO 21287 body drops into tight chip-guard spaces on CNC fixtures, and the 50 mm adjustment window lets you tune the eject position without re-plumbing.
Case reject pusher
On packaging lines the 60 mm stroke with adjustable stop pushes misaligned cartons off a conveyor, and the male rod thread accepts a standard pusher plate directly.
Is the Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X60-50B the Right Cylinder?
At 0.5 MPa this 63 mm bore delivers 1558.6 N push, which sits between the 50 mm bore (981.7 N) and the 80 mm bore (2513.3 N) - pick 50 mm if your load is under about 590 N of real work, or step up to 80 mm for heavier clamping. The 50 mm adjustment window lets one cylinder serve several jig depths, but remember the stop screw only shortens the extend stroke; it is a mechanical end stop, not a mid-stroke lock, so a load can still drift if air is lost. FA flange or LB foot mounts plus I/Y rod knuckles bolt to the ISO 21287 face, and the optional -S magnet enables CMSE / DMSE position switches.
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 ACEJ63X60-50B FAQ
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa push rises to 2182.1 N and pull to 2041.3 N, with a theoretical maximum of 317.9 kgf at 1.0 MPa. The -50 code is a 50 mm adjustment window: an external stop screw shortens the 60 mm extend stroke by up to 50 mm, so the usable range is 10-60 mm. It runs double acting on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, with a fixed TPU bumper at both ends.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits shallow jigs and gantries. FA flange and LB foot mounts plus I/Y rod knuckles bolt to the standard face. Sensing is not included: this model has no magnet, but ordering the optional -S version lets CMSE or DMSE switches detect end positions. The bumper only decelerates at the ends and never holds a load against air loss.
