About the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ40X10-10
The ACEJ40X10-10 is a double acting ISO 21287 compact cylinder with an adjustable extend stroke: an external stop screw trims the 10 mm stroke down within the ordered -10 window, giving a usable range of 0-10 mm. At 0.5 MPa it pushes 628.3 N and pulls 571.8 N, rising to 879.6 N at 0.7 MPa, with a theoretical maximum of 128.1 kgf at 1.0 MPa. As a rule of thumb, plan on roughly 377 N of real work at 0.5 MPa, which is about 38 kg of vertical lifting capacity with a 2:1 margin.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so this 40 mm bore unit slots into tight clamping fixtures and shallow machine pockets. A hard-anodized aluminium body carries an S45C hard-chrome plated 12 mm rod, fixed TPU bumpers absorb end-of-stroke energy at both ends, and FA flange or LB foot mounts bolt straight to the standard face. Note that this unit has no magnet fitted; order the optional -S code if you need CMSE / DMSE switch sensing.

Where the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ40X10-10 Is Used
Short-travel press fitting
The 0-10 mm adjustable range suits pressing bearings or bushings into housings on a small assembly bench, where 628.3 N at 0.5 MPa is enough for light interference fits.
Fixture clamping on CNC fixtures
Trim the stroke with the stop screw to clamp machined parts in jigs without over-squeezing, and the compact body fits inside fixture plates where a full-length cylinder cannot.
Carton hold-down on packing lines
A 10 mm stroke is ideal for holding carton flaps or trays under a sealing head, with fixed TPU bumpers softening every cycle at 30-500 mm/s.
Is the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ40X10-10 the Right Cylinder?
At 628.3 N push, the 40 mm bore sits between the 32 mm (402.1 N) and 50 mm (981.7 N) options at 0.5 MPa - pick 32 mm for lighter clamps, 50 mm when you need nearly double the force. The stop screw only shortens the extend stroke and is a mechanical end stop, not a mid-stroke lock, so the rod will still drift if air is lost. FA flange and LB foot mounts plus I/Y rod knuckles fit standard ISO 21287 fixtures, and the optional -S magnet enables CMSE / DMSE switches when position feedback is required.
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 ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ40X10-10 FAQ
At 0.5 MPa it pushes 628.3 N and pulls 571.8 N; at 0.7 MPa push is 879.6 N and pull 800.5 N; theoretical maximum is 128.1 kgf at 1.0 MPa. Operating pressure is 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, air filtered to 40 um. Port is 1/8" PT, rod thread M8x1.25 female, and the extend stroke is adjustable from 0-10 mm via the stop screw.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, making it easy to fit into shallow fixtures and guarded spaces. FA flange and LB foot mounts bolt to the standard face. Sensing requires the optional -S magnet code; this model has no magnet, so CMSE / DMSE switches cannot be mounted unless you order the -S version.
