About the Airtac ACE Compact Cylinder ACE20X35B
This ACE20X35B is a double acting ISO 21287 compact cylinder with a 20 mm bore and a 35 mm stroke. Its hard-anodized aluminium body is about half the mounting length of an ISO 15552 profile cylinder, making it a fit for tight fixtures. The male rod thread (B code) simplifies mounting to linkages or tooling.
At 0.5 MPa it pushes with 157.1 N and pulls with 117.8 N, so it suits light assembly tasks. As a guide, plan for about 9.6 kg of real vertical work at 0.5 MPa (0.6 x 157.1 N divided by 9.81) to keep a safety margin. The fixed TPU bumper absorbs end-of-stroke impact, and the M5x0.8 port keeps plumbing compact.

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 (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 ACE20X35B Is Used
Light Assembly Jig
Use the 157.1 N push to actuate a small locating pin or clamp in a benchtop assembly fixture for electronics or small parts.
Label Applicator
Drive a label tamp head with the 35 mm stroke and 117.8 N pull to press labels onto small cartons or bottles on a packaging line.
Guard Door Actuator
Open a small plexiglass guard door on a machine with the compact body, saving space compared to a longer profile cylinder.
Is the Airtac ACE Compact Cylinder ACE20X35B the Right Cylinder?
For a smaller option, the ACE16X35 offers 100.5 N push at 0.5 MPa, while the ACE25X35 steps up to 245.4 N push. This 20 mm bore unit is a middle ground for light pick-and-place or clamping. Since this model has no -S code, it lacks a magnet, so CMSE or DMSE sensors cannot be fitted; order the -S version if you need position sensing. The male rod thread (B) suits direct coupling to a clevis or rod end.
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 ACE20X35B FAQ
At 0.5 MPa, push is 157.1 N and pull 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.
No, this ACE20X35B has no magnet because the -S code is absent. To use CMSE or DMSE switches, you must order the -S variant. The fixed TPU bumper at both ends only absorbs impact, not a locking mechanism.
