Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X175-40S
The AirTAC Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X175-40S is a genuine double acting, adjustable stroke ISO 21287 compact air cylinder with a Ø32mm bore and 175mm stroke, 1/8" air ports and a hard-anodized aluminium body. Its short compact envelope saves about 50% of the mounting length of an ISO 15552 profile cylinder.

About the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X175-40S
A double acting ISO 21287 compact cylinder with an adjustable extend stroke, the ACEJ32X175-40S delivers 402.1 N push and 345.6 N pull at 0.5 MPa (563 N and 483.8 N at 0.7 MPa) from a 32 mm bore. Its hard-anodized aluminium body and S45C hard-chrome plated rod suit 0.15-1.0 MPa (22-145 psi) air circuits running 30-500 mm/s. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs, guards and gantry frames.
The -40 code is the adjustable window: an external stop screw trims the 175 mm extend stroke down to 135 mm on site, so one cylinder covers a 135-175 mm range without re-plumbing. In practice, plan on roughly 241 N of usable push at 0.5 MPa, which lifts about 20 kg vertically with a 2:1 margin. A fixed TPU bumper at each end absorbs end-of-stroke energy, and the fitted -S magnet lets CMSE / DMSE switches report position along the body's magnet slots.

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 ACEJ32X175-40S Is Used
Fixture clamping on CNC pallets
The 135-175 mm adjustable window lets one cylinder serve several pallet heights, with about 241 N of working push at 0.5 MPa holding steel parts in milling fixtures.
Packaging line pushers
A 175 mm stroke ejects cartons from a conveyor lane, and the compact body fits under low guarding where an ISO 15552 profile cylinder would not.
Gantry pick stations with position feedback
The fitted -S magnet accepts CMSE / DMSE switches at both ends of the 135-175 mm range, confirming part presence on automated assembly gantries.
Is the Airtac ACEJ32~40 Adjustable Cushion Compact Cylinder ACEJ32X175-40S the Right Cylinder?
At 402.1 N push (0.5 MPa) this bore sits between the 25 mm (245.4 N) and 40 mm (628.3 N) options, so pick it for mid-range clamping or transfer loads around 240 N working force. Remember the stop screw is a mechanical end stop only: on air loss the piston drifts, so add a separate valve or lock if the load must be held. FA flange, LB foot and I/Y rod knuckles bolt to the ISO 21287 face; the female M8x1.25 rod thread takes standard tooling plates. The 1/8" port matches bores 32-63.
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 ACEJ32X175-40S FAQ
At 0.5 MPa it pushes 402.1 N and pulls 345.6 N; at 0.7 MPa, 563 N push and 483.8 N pull; theoretical maximum is 82 kgf at 1.0 MPa. The -40 code means an external stop screw shortens the 175 mm extend stroke by up to 40 mm, giving a usable 135-175 mm range. It is double acting, runs 30-500 mm/s on 0.15-1.0 MPa (22-145 psi) air, and the stop is an end stop, not a mid-stroke lock.
This model carries the optional -S magnet, so CMSE reed or DMSE solid-state switches can be clipped into the body slots for end-of-stroke signals. FA flange, LB foot, FTC brackets and I/Y rod knuckles bolt to the ISO 21287 mounting face, and the female M8x1.25 rod thread accepts standard tooling. The body is hard-anodized aluminium with a fixed TPU bumper at each end; outline dimensions should be confirmed from the datasheet.
