Airtac ACE Compact Cylinder ACE20X90
The AirTAC Airtac ACE Compact Cylinder ACE20X90 is a genuine double acting ISO 21287 compact air cylinder with a Ø20mm bore and 90mm stroke, M5×0.8 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 ACE20X90
This AirTAC ACE20X90 is a double acting ISO 21287 compact cylinder with a 20 mm bore and 90 mm stroke. It delivers a 157.1 N push force at 0.5 MPa, enough for light assembly and clamping tasks where space is tight.
The hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder, so it fits inside machine guards and compact jigs. The rod is S45C carbon steel with hard-chrome plating, and a fixed TPU bumper absorbs energy at both stroke ends. For a safe working load, plan for about 94 N of real work at 0.5 MPa, which lifts roughly 9.6 kg vertically with a 2:1 safety margin.

Where the Airtac ACE Compact Cylinder ACE20X90 Is Used
Compact Jig Clamping
Use in a CNC fixture to clamp small parts with 157.1 N force at 0.5 MPa, fitting into a 90 mm stroke envelope where a full-length cylinder would not fit.
Light Conveyor Stop
Actuate a stop gate on a packaging line, pushing with 157.1 N to divert lightweight cartons without taking up extra mounting length.
Guard Door Interlock
Drive a safety interlock pin on a machine guard, using the 90 mm stroke to engage a lock while the compact body fits within the guard frame.
Is the Airtac ACE Compact Cylinder ACE20X90 the Right Cylinder?
For a lighter 16 mm bore, the ACE16X90 offers 100.5 N push at 0.5 MPa, while stepping up to a 25 mm bore gives 245.4 N push. This ACE20X90 suits applications needing moderate force in a compact envelope. Since this model has no -S code, it has no magnet, so CMSE or DMSE sensors cannot be mounted; order the -S version if you need position sensing. The M5x0.8 port and female M6x1.0 rod thread are standard for this bore.
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 ACE20X90 FAQ
At 0.5 MPa, push is 157.1 N and pull is 117.8 N. At 0.7 MPa, push rises to 219.9 N and pull to 164.9 N. The theoretical maximum force at 1.0 MPa is 32 kgf. Operating pressure range is 0.15-1.0 MPa (22-145 psi), with proof pressure at 1.5 MPa (215 psi).
The ISO 21287 design saves about 50% of the mounting length compared to an ISO 15552 profile cylinder, making it ideal for tight spaces. It uses a fixed TPU bumper at both ends to absorb impact, not an adjustable cushion. The bumper does not lock or hold a load; if you need position holding, add a rod lock or pilot check valve.
