Airtac ACE Compact Cylinder ACE50X35S
The AirTAC Airtac ACE Compact Cylinder ACE50X35S is a genuine double acting ISO 21287 compact air cylinder with a Ø50mm bore and 35mm stroke, 1/8" 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 ACE50X35S
This AirTAC ACE50X35S is a double acting ISO 21287 compact cylinder that extends and retracts its 16 mm rod with air pressure on both strokes. It delivers 981.7 N of push force at 0.5 MPa, so a safe working load for real applications is about 589 N - enough to lift roughly 60 kg vertically with a 2:1 safety margin.
The hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder, letting it fit into tight jig fixtures and machine guards. The optional -S magnet is already fitted on this model, so you can mount CMSE or DMSE reed and solid-state switches directly on the body for position sensing.

Where the Airtac ACE Compact Cylinder ACE50X35S Is Used
Fixture Clamping
Use the 981.7 N push force to clamp sheet metal parts in a CNC milling fixture, where the compact body fits between vise jaws and the stroke is enough for quick part release.
Carton Tamping
In a packaging line, this cylinder can tamp folded cardboard boxes into a chute, using its 881.2 N pull stroke to retract the tamping plate after each cycle.
Stop Gate
Mount the ACE50X35S on a conveyor to raise and lower a stop gate for product spacing, with the optional magnet feeding position signals to a PLC via a CMSE switch.
Is the Airtac ACE Compact Cylinder ACE50X35S the Right Cylinder?
For lighter duty, the ACE40X35 offers 628.3 N push at 0.5 MPa, while the ACE63X35 steps up to 1558.6 N push. Since this cylinder is double acting, it will not hold its position if air pressure is lost - for a held load, add a rod lock or pilot check valve. The 1/8" port suits standard fittings, and the female M10x1.5 rod thread accepts common attachments.
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 ACE50X35S FAQ
At 0.5 MPa, push force is 981.7 N and pull force is 881.2 N. At 0.7 MPa, push is 1374.4 N and pull is 1233.7 N. The theoretical maximum force at 1.0 MPa is 200.2 kgf.
The magnet is an optional -S code, and this ACE50X35S includes it. With the magnet fitted, you can mount CMSE or DMSE reed and solid-state switches. Without the -S code, no magnet is present, so sensors cannot be used.
