About the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-100B
The ACEJ32X100-100B is a double acting ISO 21287 compact cylinder with an adjustable extend stroke. Its 32 mm bore delivers 402.1 N push and 345.6 N pull at 0.5 MPa, rising to 563 N push at 0.7 MPa, with a theoretical maximum of 82 kgf at 1.0 MPa. An external stop screw trims the extend stroke anywhere within the ordered 100 mm window, so one cylinder can be tuned on the machine to travel anywhere from 0 to 100 mm. The male rod thread (B code) bolts straight to external tooling.
The hard-anodized aluminium body with an S45C hard-chrome-plated rod saves about 50% of the mounting length of an ISO 15552 profile cylinder, which makes it a strong fit for tight jigs, guarding and gantry frames. A fixed TPU bumper at each end absorbs end-of-stroke shock, and the stop screw is purely a mechanical end stop, not a mid-stroke lock, so the piston still drifts if air is lost. A practical sizing rule: at 0.5 MPa, plan roughly 240 N of real work, which is about 24 kg of vertical lift with a 2:1 margin. Note there is no magnet fitted; order the optional -S code if CMSE or DMSE switch sensing is needed.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-100B Is Used
Fixture clamp tuning
On a machining-centre jig, the stop screw sets the exact clamp travel for each part family within the 0-100 mm range, so one cylinder handles short and tall castings without re-plumbing.
Packaging pusher station
With 402.1 N push at 0.5 MPa, the cylinder kicks cartons off a conveyor into a lane; the male rod thread takes a formed pusher paddle directly.
Press ejection ram
In a small stamping or moulding cell, the 563 N push at 0.7 MPa ejects finished parts, and the 100 mm window lets maintenance trim the eject length to the die in use.
Is the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X100-100B the Right Cylinder?
At 402.1 N push at 0.5 MPa, this 32 mm bore suits clamping, pressing and positioning loads in the 20-25 kg class. Step down to the 25 mm bore (245.4 N push at 0.5 MPa) for lighter fixtures, or up to the 40 mm bore (628.3 N push at 0.5 MPa) when the load grows. The 100 mm adjustment window lets one part number serve several stroke points on the same line. FA flange or LB foot mounts plus I and Y rod knuckles attach to the ISO 21287 face, and the male rod thread suits clevis-style tooling. Remember the adjuster is an end stop only: it will not hold a load against gravity if air pressure drops.
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 ACEJ32X100-100B FAQ
At 0.5 MPa it pushes 402.1 N and pulls 345.6 N; at 0.7 MPa it pushes 563 N and pulls 483.8 N; theoretical maximum force is 82 kgf at 1.0 MPa. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C, speed 30-500 mm/s, with a 12 mm rod and 1/8" ports. The extend stroke is adjustable from 0 to 100 mm via the external stop screw.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into cramped guards and gantries. It carries a fixed TPU bumper at both ends to soften end-of-stroke impact. FA flange, LB foot and rod knuckle mounts bolt to the standard face. Sensing requires the optional -S magnet code; this model (no S) has no magnet, so CMSE or DMSE switches cannot be fitted unless that option is ordered.
