About the Airtac ACE Compact Cylinder ACE20X75B
This AirTAC ACE20X75B is a double acting ISO 21287 compact cylinder with a 20 mm bore and a 75 mm stroke. Its short, hard-anodized aluminum body takes up about 50% less mounting length than an ISO 15552 profile cylinder, making it a fit for tight machine guarding and compact jigs. The male rod end (B code) simplifies linkage to your tooling.
At 0.5 MPa, this unit pushes with 157.1 N and pulls with 117.8 N, so plan for roughly 9.6 kg of safe vertical lifting capacity with a 2:1 safety margin. The fixed TPU bumper absorbs end-of-stroke impact, and the M5x0.8 port accepts standard fittings. This version has no magnet, so CMSE or DMSE sensors are not an option unless you order the -S variant.

Theoretical Output Force (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 118 N |
| 0.7 MPa | 220 N | 165 N |
| Max (@1.0 MPa) | 32 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 ACE20X75B Is Used
Fixture Clamping
Use the ACE20X75B to clamp small parts in a CNC vise or a custom jig, where its 157.1 N push at 0.5 MPa holds components securely without taking up excessive space.
Label Applicator
Drive a label applicator head in a packaging line. The 75 mm stroke provides enough travel to reach and press labels onto cartons, while the compact body fits within the machine frame.
Guard Door Stop
Actuate a small safety guard door stop on a semi-automatic assembly machine. The 117.8 N pull force at 0.5 MPa is enough to move a lightweight interlock pin, and the short body mounts easily behind the guard.
Is the Airtac ACE Compact Cylinder ACE20X75B the Right Cylinder?
For a lighter push, the ACE16X75 produces 100.5 N at 0.5 MPa, while stepping up to the ACE25X75 delivers 245.4 N. Choose the ACE20X75B when you need a balance of force and compact size. Since this model lacks the optional -S magnet, it cannot be used with magnetic switches; order ACE20X75SB if you need that capability. The male rod thread (B) is suited for direct coupling to a load or fixture.
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 ACE20X75B 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).
No, this specific model does not have the optional -S magnet, so CMSE or DMSE switches cannot be mounted. If you need sensor capability, you must order the ACE20X75SB version, which includes the magnet. The cylinder itself features a fixed TPU bumper at both ends for deceleration.
