Airtac ACE Compact Cylinder ACE50X25SB
The AirTAC Airtac ACE Compact Cylinder ACE50X25SB is a genuine double acting ISO 21287 compact air cylinder with a Ø50mm bore and 25mm 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 ACE50X25SB
This AirTAC ACE50X25SB is a double acting ISO 21287 compact cylinder with a 50 mm bore and a 25 mm stroke. It delivers a push force of 981.7 N and a pull force of 881.2 N at 0.5 MPa, with a theoretical maximum of 200.2 kgf at 1.0 MPa. The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, fitting into tight machine frames and guarding where a full-length cylinder will not go.
This model carries the optional -S magnet, so CMSE or DMSE reed and solid-state switches can be mounted for position sensing. For real work, plan on about 589 N of usable force at 0.5 MPa, which lifts roughly 60 kg vertically with a 2:1 safety margin. The fixed TPU bumper at both ends absorbs end-of-stroke energy, and the hard-anodized aluminium body with a hard-chrome S45C rod resists wear in continuous cycling.

Where the Airtac ACE Compact Cylinder ACE50X25SB Is Used
Jig Clamping
Clamp a 60 kg fixture in a CNC milling vise with 981.7 N push force at 0.5 MPa, using the compact body to fit under the spindle guard.
Sorting Gate
Divert boxes on a packaging line with a 25 mm stroke, pushing at 881.2 N pull to retract the gate quickly between cycles.
Press Ram
Drive a small arbor press for stamping metal tags, using the 1374.4 N push at 0.7 MPa to form parts up to 2 mm thick.
Is the Airtac ACE Compact Cylinder ACE50X25SB the Right Cylinder?
For lighter duty, the ACE40X25 offers 628.3 N push at 0.5 MPa, while the ACE63X25 steps up to 1558.6 N push. This 50 mm bore is a balanced choice for medium-force automation. The male rod thread (B code) simplifies mounting of rod-end accessories without a separate adapter. The 1/8" port suits standard pneumatic fittings, and the optional magnet is already fitted, so you can wire CMSE switches directly. Remember, without air pressure the rod will drift if a load is applied; use a rod lock or pilot check valve for 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 ACE50X25SB 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. Operating pressure is 0.15-1.0 MPa (22-145 psi).
This ACE50X25SB includes the optional -S magnet, so you can mount CMSE or DMSE reed or solid-state switches. Without the -S code, no magnet is present. The fixed TPU bumper absorbs end-of-stroke impact but does not lock or hold a load.
