Airtac ACE Compact Cylinder ACE50X90B
The AirTAC Airtac ACE Compact Cylinder ACE50X90B is a genuine double acting ISO 21287 compact air cylinder with a Ø50mm bore and 90mm 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 ACE50X90B
This AirTAC ACE50X90B is a double acting ISO 21287 compact cylinder with a 50 mm bore and 90 mm stroke, delivering 981.7 N of push force at 0.5 MPa. Its hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight machine guarding and compact jigs where a full-length cylinder would not. The fixed TPU bumper at both ends absorbs end-of-stroke impact, and the S45C hard-chrome rod resists wear in repetitive cycles.
With a 981.7 N push at 0.5 MPa, plan for about 589 N of usable force for real work, which lifts roughly 60 kg vertically with a 2:1 safety margin. The 1/8" port suits standard fittings, and the male rod thread (B code) allows direct coupling to linkages without a rod-end adapter. This model has no magnet, so CMSE or DMSE sensors cannot be mounted unless you order the optional -S version.

Where the Airtac ACE Compact Cylinder ACE50X90B Is Used
Fixture Clamping
Use the 981.7 N push to clamp sheet-metal parts in a welding fixture, where the compact body fits between locating pins and the 90 mm stroke clears the part for loading.
Carton Pusher
In a carton-erecting line, this cylinder pushes folded boxes into position with 881.2 N pull on the return, and the short body fits under the conveyor frame.
Guard Door Actuator
Mount this ACE50X90B to slide a machine guard door open and closed; the 90 mm stroke matches a compact guard panel, and the TPU bumper softens the stop.
Is the Airtac ACE Compact Cylinder ACE50X90B the Right Cylinder?
For a lighter duty, the ACE40X90 offers 628.3 N push at 0.5 MPa, while stepping up to the ACE63X90 gives 1558.6 N push for heavier loads. Since this ACE50X90B has a male rod thread, it is ready for clevis or fork mounts, and the FA/FB flange or LB foot brackets bolt directly to the ISO 21287 face. Remember, this plain cylinder does not hold its position when air is lost, so add a rod lock or pilot check valve if the load must stay put.
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 ACE50X90B FAQ
At 0.5 MPa, push is 981.7 N and pull is 881.2 N. At 0.7 MPa, push is 1374.4 N and pull is 1233.7 N. The theoretical maximum force is 200.2 kgf at 1.0 MPa.
No, this model has no magnet, so CMSE or DMSE switches cannot be mounted. You need the optional -S code (e.g., ACE50X90SB) to get the built-in magnet for sensor feedback.
