About the Airtac ACE Compact Cylinder ACE20X30SB
This AirTAC ACE20X30SB is a double acting ISO 21287 compact cylinder with a 20 mm bore and 30 mm stroke. It delivers 157.1 N push and 117.8 N pull at 0.5 MPa, with a theoretical maximum of 32 kgf at 1.0 MPa, making it a solid choice for light assembly tasks.
The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, fitting into tight jigs and guards. The optional -S magnet is fitted here, enabling CMSE or DMSE switches for position sensing. For a 2:1 safety margin, plan to lift about 8 kg vertically (157.1 N / 9.81 / 2), so match it to real part weights in your fixture.

Where the Airtac ACE Compact Cylinder ACE20X30SB Is Used
Small Part Clamping
Use in a jig to clamp small plastic or aluminum parts during drilling or light milling, where the 157.1 N push secures the workpiece without deformation.
Label Applicator
Drive a label applicator head in a packaging line, using the 30 mm stroke to press labels onto boxes or bottles with consistent force and speed.
Test Probe Actuator
Actuate a test probe in an electronics QC station, where the compact body fits under a conveyor and the 117.8 N pull retracts the probe after contact.
Is the Airtac ACE Compact Cylinder ACE20X30SB the Right Cylinder?
For lighter loads, consider the 16 mm bore with 100.5 N push, while the 25 mm bore offers 245.4 N push if you need more force. This 20 mm bore with a 30 mm stroke suits compact spaces where a shorter stroke is adequate. The male rod thread (B code) simplifies mounting with rod-end accessories, and the M5x0.8 port is standard for this bore size. Since the magnet is fitted, you can add CMSE or DMSE sensors for position feedback, but remember this cylinder does not hold position without air pressure.
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 ACE20X30SB 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), with a proof pressure of 1.5 MPa (215 psi).
The ACE20X30SB has a short body that saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits in tight spaces like machine guards or gantries. It uses a fixed TPU bumper at both ends to absorb impact, and the hard-anodized aluminum body resists wear. The optional -S magnet is fitted here, allowing CMSE or DMSE switches for position sensing.
