Airtac ACE Compact Cylinder ACE32X45SB
The AirTAC Airtac ACE Compact Cylinder ACE32X45SB is a genuine double acting ISO 21287 compact air cylinder with a Ø32mm bore and 45mm 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 ACE Compact Cylinder ACE32X45SB
This AirTAC ACE32X45SB is a double acting ISO 21287 compact cylinder that extends and retracts its 12 mm rod with air pressure. With a 32 mm bore it delivers 402.1 N of push force at 0.5 MPa, enough to drive a small clamp or a light indexing stop in a pick-and-place cell.
The ISO 21287 short body takes up about 50% less mounting length than an ISO 15552 profile cylinder, which lets you tuck it into a tight guard or between machine frames. The optional -S magnet is fitted here, so CMSE or DMSE reed and solid-state switches can bolt onto the body slots for position sensing. For a real-world load, plan on about 24.6 kg of usable force at 0.5 MPa (0.6 times the push rating), so it can safely lift a small fixture or press a light component.

Specifications follow the official AirTAC ACE-series (ISO 21287) datasheet. Body: hard-anodized aluminium alloy; piston rod: S45C carbon steel with hard-chrome plating. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G. A built-in magnet is OPTIONAL — add the -S code to fit CMSE / DMSE position sensors.
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 ACE Compact Cylinder ACE32X45SB Is Used
Fixture Clamping
Use the 402.1 N push at 0.5 MPa to clamp a small aluminum part in a CNC fixture, with the compact body fitting under a low-profile guard.
Light Indexing Stop
Actuate a stop pin on a conveyor line to separate small cartons, relying on the 45 mm stroke to clear the product path and the TPU bumper to handle quick cycles.
Gantry Pick-and-Place
Mount this cylinder on a gantry Z-axis to lift a 2 kg gripper, using the 345.6 N pull force at 0.5 MPa to retract the rod reliably against a light spring load.
Is the Airtac ACE Compact Cylinder ACE32X45SB the Right Cylinder?
For a lighter duty, the ACE25X45 offers 245.4 N push at 0.5 MPa, while stepping up to the ACE40X45 gives you 628.3 N push at the same pressure. This 32 mm bore sits in the middle, balancing force and size for medium automation tasks. The male rod thread (B code) simplifies mounting to a clevis or rod end, and the 1/8" port accepts standard fittings.
Since the magnet is fitted, you can add CMSE or DMSE switches for end-of-stroke detection. This cylinder is double acting, so it will not hold its position if air pressure is lost; for a held load, add a pilot check valve or a rod lock. The fixed TPU bumper absorbs energy at both ends, but it is not a brake.
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 ACE32X45SB FAQ
At 0.5 MPa, the push force is 402.1 N and the pull force is 345.6 N. At 0.7 MPa, push is 563 N and pull is 483.8 N. The theoretical maximum force at 1.0 MPa is 82 kgf. These figures are based on the 32 mm bore and 12 mm rod.
The ACE32X45SB has a hard-anodized aluminum body that is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight spaces like inside a machine guard or between vertical supports. The fixed TPU bumper at both ends absorbs end-of-stroke impact, and the optional -S magnet allows you to attach CMSE or DMSE sensors for position feedback.
