About the Airtac ACE Compact Cylinder ACE32X25SB
This AirTAC ACE32X25SB is a double acting compact cylinder that uses air to both extend and retract its 12 mm rod. With a 32 mm bore it delivers 402.1 N of push force at 0.5 MPa, making it a solid choice for light assembly tasks. The short ISO 21287 body takes up about 50% less mounting length than an ISO 15552 profile cylinder, so it slips into tight machine frames and guarding where a longer unit will not fit.
The hard-anodized aluminium body and S45C hard-chrome plated rod resist wear in continuous cycling. This model carries the optional -S magnet, so you can mount CMSE or DMSE reed and solid-state switches directly on the body for position sensing. A fixed TPU bumper at each end absorbs impact energy, and for a real-world rule of thumb, plan to use about 241 N of the rated force for safe work at 0.5 MPa, which equals lifting roughly 25 kg vertically with a 2:1 margin.

Where the Airtac ACE Compact Cylinder ACE32X25SB Is Used
Small Part Press
Use this 32 mm bore cylinder to press small bushings or bearings into plastic housings. The 402.1 N push at 0.5 MPa provides enough force for light interference fits, and the compact body fits under a bench-mounted press frame.
Conveyor Stop Gate
Mount this cylinder on a packaging line to raise a stop gate that diverts boxes. With a 25 mm stroke, it quickly lifts a lightweight aluminum gate, and the optional -S magnet lets you confirm the gate position with a CMSE switch.
Fixture Clamp
In a CNC machining cell, use this cylinder to clamp a small workpiece against a locating pin. The short ISO 21287 body fits within the machine's work envelope, and the male rod thread allows a custom clamp arm to be bolted directly.
Is the Airtac ACE Compact Cylinder ACE32X25SB the Right Cylinder?
For a lighter duty, the ACE25X25 with a 25 mm bore gives 245.4 N push at 0.5 MPa, while stepping up to the ACE40X25 with a 40 mm bore provides 628.3 N push at the same pressure. This 32 mm bore version balances compact size with useful force for small jigs and fixtures. Since the stroke is 25 mm, well under the 200 mm maximum standard for this bore, you get a standard off-the-shelf unit. The male rod thread (B code) simplifies attaching custom tooling, and the 1/8" port matches common air line sizes. Remember, this cylinder does not hold its position if air pressure is lost, so for a held load add a rod lock or pilot check valve.
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 ACE Compact Cylinder ACE32X25SB FAQ
At 0.5 MPa, this cylinder provides 402.1 N push and 345.6 N pull. At 0.7 MPa, it provides 563 N push and 483.8 N pull. The theoretical maximum force is 82 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa (22-145 psi), and the proof pressure is 1.5 MPa (215 psi).
The ACE32X25SB has a short body that saves about 50% of the mounting length compared to an ISO 15552 profile cylinder. This makes it ideal for tight spaces inside machine guards or on moving gantries. It also features a fixed TPU bumper at both ends to absorb impact, and the optional -S magnet allows for CMSE or DMSE switch mounting for position feedback.
