Airtac ACE Compact Cylinder ACE50X35SB
The AirTAC Airtac ACE Compact Cylinder ACE50X35SB 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 ACE50X35SB
This AirTAC ACE50X35SB is a double acting ISO 21287 compact cylinder with a 50 mm bore and 35 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, fitting into tight machine frames and guarding where a full-length unit won't go.
The S45C piston rod is hard-chrome plated and has a male thread end, while the fixed TPU bumper absorbs energy at both ends of the stroke. With the -S magnet fitted, this model accepts CMSE or DMSE reed and solid-state switches for position sensing, and it carries a 1/8" port for easy airline connection.

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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 881 N |
| 0.7 MPa | 1374 N | 1234 N |
| Max (@1.0 MPa) | 200 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 ACE50X35SB Is Used
Jig Clamping
Use in a CNC machine fixture to clamp a 50 mm thick workpiece with 981.7 N of force, where the short body fits under the spindle guard.
Carton Pusher
Mount on a packaging line to push a 35 mm tall carton into a sealing station, using the 881.2 N retract force to pull back quickly.
Parts Ejector
Install in a press tool to eject a stamped metal part after forming, relying on the fixed TPU bumper to stop the rod gently at the end of the 35 mm stroke.
Is the Airtac ACE Compact Cylinder ACE50X35SB the Right Cylinder?
For a lighter duty, the ACE40X35 offers 628.3 N push at 0.5 MPa, while stepping up to the ACE63X35 gives 1558.6 N push at 0.5 MPa. This 50 mm bore unit suits medium-force applications where you need to move a load of about 60 kg vertically with a 2:1 safety margin, based on its 981.7 N push force.
Choose FA or FB flange, LB foot, CA or CB clevis, CR, SDB pivot, or FTC mounting brackets that bolt directly to the ISO 21287 face. Since this model includes the optional -S magnet, you can add CMSE or DMSE switches for end-of-stroke detection, but remember the cylinder does not hold position if air pressure is lost.
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 ACE50X35SB FAQ
At 0.5 MPa, the push force is 981.7 N and the 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 is 200.2 kgf at 1.0 MPa.
The ACE50X35SB body is about 50% shorter than an ISO 15552 profile cylinder, so it mounts inside machine guards or between frame members where a full-length cylinder won't fit. The optional -S magnet lets you add CMSE or DMSE switches for position feedback, and the fixed TPU bumper absorbs end-of-stroke impact without needing adjustment.
