About the Airtac ACE Compact Cylinder ACE20X45SB
This AirTAC ACE20X45SB is a double acting compact cylinder built to ISO 21287, with a 20 mm bore and 45 mm stroke. It delivers 157.1 N push and 117.8 N pull at 0.5 MPa, and 219.9 N push at 0.7 MPa, with a theoretical maximum of 32 kgf at 1.0 MPa. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits into tight automation frames where a full-length cylinder will not.
This model includes the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be mounted for position sensing. The hard-anodized aluminium body and S45C hard-chrome plated rod resist wear, and the fixed TPU bumper absorbs end-of-stroke impact. For a real-world rule of thumb, plan for about 94 N of safe working force at 0.5 MPa, which lifts roughly 9.6 kg vertically with a 2:1 safety margin.

Where the Airtac ACE Compact Cylinder ACE20X45SB Is Used
Compact Jig Clamping
Use in a small pneumatic jig on a benchtop press to clamp thin metal parts during drilling. The 45 mm stroke and 157.1 N push at 0.5 MPa hold fixtures firmly, and the short body fits under a worktable guard.
Sorting Gate Actuator
Mount on a packaging conveyor to divert lightweight cartons onto a side lane. The 20 mm bore provides enough force to move a small flap, and the male rod thread connects directly to a linkage without extra adapters.
Guard Door Interlock
Actuate a safety interlock on a small machine guard in a food processing line. The compact body fits within the guard frame, and the optional -S magnet lets a CMSE switch confirm the guard is closed before the machine starts.
Is the Airtac ACE Compact Cylinder ACE20X45SB the Right Cylinder?
When sizing, compare this 20 mm bore to a 16 mm bore that pushes 100.5 N at 0.5 MPa, or step up to a 25 mm bore that pushes 245.4 N at 0.5 MPa. This 45 mm stroke is within the 100 mm maximum standard stroke for bore 20, so it ships as a standard item. The male rod thread (B code) simplifies mounting to a load, and the M5x0.8 port suits small-bore air circuits. Since this unit has the -S magnet, order CMSE or DMSE switches to confirm position; without the -S code, no magnet is present. For applications that must hold a load when air is lost, add a rod lock or pilot check valve, as this cylinder does not lock by itself.
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 ACE20X45SB FAQ
At 0.5 MPa, the push force is 157.1 N and the pull force is 117.8 N. At 0.7 MPa, push is 219.9 N and pull is 164.9 N. The theoretical maximum force is 32 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa (22-145 psi), and the speed range is 30-500 mm/s.
The ACE20X45SB has a short body that saves about 50% of the mounting length of an ISO 15552 profile cylinder, making it ideal for tight spaces. It has a fixed TPU bumper at both ends to absorb impact, and the hard-anodized aluminium body resists wear. This model includes the optional -S magnet, so you can add CMSE or DMSE sensors for position feedback.
