About the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X80-50S
The ACEJ32X80-50S 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 at 0.7 MPa, with a theoretical peak of 82 kgf at 1.0 MPa. The -50 code gives a 50 mm adjustment window: an external stop screw trims the 80 mm stroke down to as little as 30 mm on site, so one cylinder covers a 30-80 mm working range without reordering. This model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be fitted for end-of-stroke sensing.
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 rule of thumb for real work: plan on roughly 241 N (about 24.6 kg of vertical lift at 0.5 MPa) rather than the full rating, and halve that again for a 2:1 margin, so it comfortably lifts about 12 kg vertically. Fixed TPU bumpers absorb end-of-stroke energy, speed spans 30-500 mm/s, and operating pressure is 0.15-1.0 MPa (22-145 psi).

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 ACEJ32X80-50S Is Used
Jig clamping on CNC fixtures
The 30-80 mm trim range lets a machinist dial the clamp stroke to each fixture, with 402.1 N push at 0.5 MPa holding parts against the locators.
Packaging line product stops
A short-body stop that saves about 50% of the mounting length of an ISO 15552 profile cylinder, ideal where guarding leaves little depth, with CMSE switches confirming the extended position.
Lab sample press station
About 12 kg of vertical lift with a 2:1 margin suits pressing caps or sample trays, and the 50 mm window absorbs fixture variations without swapping cylinders.
Is the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X80-50S the Right Cylinder?
At 32 mm bore this sits between the 25 mm (245.4 N push at 0.5 MPa) and the 40 mm (628.3 N push at 0.5 MPa) sizes: choose the 25 mm if your load is under about 15 kg equivalent, step up to 40 mm if you need more than roughly 24 kg of usable force. Remember the stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock, so the rod can still drift if air is lost. FA flange or LB foot mounting bolts to the ISO 21287 face, the rod end is female M8x1.25, and the fitted -S magnet lets you add CMSE / DMSE switches whenever position feedback is needed.
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 ACEJ32X80-50S FAQ
At 0.5 MPa it pushes 402.1 N and pulls 345.6 N; at 0.7 MPa those rise to 563 N and 483.8 N; theoretical maximum is 82 kgf at 1.0 MPa. The 32 mm bore 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 1/8" port and female M8x1.25 rod thread.
The -50 code means an external stop screw shortens the 80 mm extend stroke by up to 50 mm, giving a usable 30-80 mm range; it is an end stop only and never holds a load if air is lost. Because this unit carries the optional -S magnet, CMSE / DMSE reed or solid-state switches can be mounted on the body slots. Fixed TPU bumpers at both ends absorb end-of-stroke energy, and FA flange or LB foot brackets bolt straight to the ISO 21287 mounting face.
