About the Airtac ACEJ125 Adjustable Compact Cylinder ACEJ125X160-10S
The ACEJ125X160-10S is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: a stop screw on the head trims the 160 mm stroke down by up to 10 mm, giving a usable range of 150-160 mm without changing the hardware. At 0.5 MPa it pushes 6135.9 N and pulls 5890.5 N, so it belongs in the heaviest force class of the ACEJ range - clamping and pressing work that smaller bores cannot reach.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters when a 125 mm bore must fit inside a press frame or weld fixture. A practical sizing rule: keep real work to roughly 3680 N (about 375 kg) of the 0.5 MPa push rating, or plan vertical lifts of about 312 kg with a 2:1 margin. The hard-anodized aluminium body carries a 25 mm S45C hard-chrome rod, a fixed TPU bumper sits at each end, and the -S magnet fitted on this model accepts CMSE / DMSE switches for end-position sensing.

Where the Airtac ACEJ125 Adjustable Compact Cylinder ACEJ125X160-10S Is Used
Heavy press-frame clamping
The 6135.9 N push at 0.5 MPa clamps large automotive stamping dies or press fixtures, and the 10 mm window lets the setter dial the extend stroke to 150-160 mm to match die height.
Weld fixture gantry actuation
A body about 50% shorter in mounting length than an ISO 15552 profile cylinder fits the 125 mm bore inside tight robot weld gantries, with the -S magnet feeding CMSE switches to the PLC.
Pallet-stacker lift assist
With about 312 kg of vertical lift at a 2:1 margin, the cylinder raises heavy pallet or drum fixtures in warehouse handling rigs, using the LB foot mount on the standard ISO 21287 face.
Is the Airtac ACEJ125 Adjustable Compact Cylinder ACEJ125X160-10S the Right Cylinder?
Compare by force at 0.5 MPa: the bore 100 ACEJ pushes 3927.0 N, while this 125 mm bore delivers 6135.9 N push and 5890.5 N pull - step up only when the extra 2200 N is genuinely needed, since the larger body needs more room and air. If 160 mm exceeds your travel, the -10 window lets you trim the extend stroke to 150-160 mm on site; remember the stop screw is a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost. Mount with FA flange or LB foot on the ISO 21287 face, add I or Y rod knuckles for side misalignment, and order PT or G ports; this unit already carries the optional -S magnet for CMSE / DMSE 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 ACEJ125 Adjustable Compact Cylinder ACEJ125X160-10S FAQ
At 0.5 MPa it pushes 6135.9 N and pulls 5890.5 N; at 0.7 MPa push rises to 8590.3 N and pull to 8246.7 N, with a theoretical maximum of 1251.4 kgf at 1.0 MPa. The -10 code is a 10 mm adjustment window: an external stop screw shortens the 160 mm extend stroke on site, so the working range is 150-160 mm. It runs double acting on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, with a 1/4" port and M16x2.0 female rod thread.
It is an ISO 21287 compact cylinder: hard-anodized aluminium body with a roller-burnished bore, 25 mm S45C hard-chrome rod, threaded aluminium covers, and a fixed TPU bumper at each end that decelerates the piston at stroke ends only - it never locks or holds a load. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder. This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be clipped into the body slots; FA flange and LB foot mounts plus I/Y knuckles bolt to the standard face.
