About the Airtac ACE Compact Cylinder ACE20X20SB
This AirTAC ACE20X20SB is a double acting ISO 21287 compact cylinder with a 20 mm bore and 20 mm stroke, delivering 157.1 N push and 117.8 N pull at 0.5 MPa. Its short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits into tight jigs and guards where a full-length cylinder will not. The optional -S magnet is fitted on this model, enabling CMSE or DMSE reed and solid-state switches for position sensing.
For real work at 0.5 MPa, plan for about 94 N of usable force, which lifts roughly 9.6 kg vertically with a 2:1 safety margin. The hard-anodized aluminium body and S45C hard-chrome rod resist wear, while the fixed TPU bumper at both ends absorbs end-of-stroke impact. This model has a male rod thread (B code) and an M5x0.8 port, operating from 0.15-1.0 MPa (22-145 psi) at speeds of 30-500 mm/s.

Where the Airtac ACE Compact Cylinder ACE20X20SB Is Used
Tight Jig Clamping
Use in a compact clamping fixture on a CNC machine where space is limited; the 20 mm stroke and 157.1 N push securely hold small parts during drilling.
Label Applicator
Drive a label applicator head in a packaging line; the short body fits between guide rails, and the 20 mm stroke precisely advances the label for each cycle.
Sorting Gate
Actuate a small diverter gate in a parts sorting conveyor; the fitted magnet works with CMSE switches to confirm gate position at 30-500 mm/s.
Is the Airtac ACE Compact Cylinder ACE20X20SB the Right Cylinder?
Choose this ACE20X20SB for compact automation tasks needing a 20 mm stroke and moderate force. If you need more thrust, step up to the ACE25X20 with 245.4 N push at 0.5 MPa; for lighter duty, the ACE16X20 offers 100.5 N push. The male rod thread simplifies mounting with rod-end accessories, and the fitted magnet allows direct attachment of CMSE or DMSE switches for position feedback. Since this is a plain double acting cylinder, it does not hold position when air is lost - use a rod lock or pilot check valve for load holding.
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 ACE20X20SB 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. The bore is 20 mm, rod is 10 mm, and the port is M5x0.8.
The body is about 50% shorter than an ISO 15552 profile cylinder, saving mounting space in tight fixtures. It has a fixed TPU bumper at both ends to absorb impact, and the optional -S magnet (fitted here) allows CMSE or DMSE sensors. The operating pressure is 0.15-1.0 MPa (22-145 psi) with a speed range of 30-500 mm/s.
