Airtac ACE Compact Cylinder ACE50X55SB
The AirTAC Airtac ACE Compact Cylinder ACE50X55SB is a genuine double acting ISO 21287 compact air cylinder with a Ø50mm bore and 55mm 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 ACE50X55SB
This AirTAC ACE50X55SB is a double acting compact cylinder with a 50 mm bore and 55 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 where a full-length unit would not. The S45C steel rod is hard-chrome plated, and the fixed TPU bumper absorbs end-of-stroke impact without the need for adjustment.
With the optional -S magnet fitted, this model is ready for CMSE or DMSE reed and solid-state switches, giving you reliable position sensing. For a real-world load, plan on about 60 kg of usable vertical lift at 0.5 MPa, which is a safe working estimate based on the 981.7 N rating. The 1/8" port and male rod thread simplify integration into standard pneumatic circuits.

Where the Airtac ACE Compact Cylinder ACE50X55SB Is Used
Fixture Clamping
Use the ACE50X55SB to clamp a workpiece in a CNC milling fixture. Its 981.7 N push force holds parts securely, and the short body fits under the spindle guard.
Package Stopper
Mount this cylinder on a conveyor line to stop or divert boxes. The 55 mm stroke is enough to raise a stop gate, and the optional magnet confirms the gate position.
Press Ram
In a small bench press, the ACE50X55SB provides a consistent 981.7 N force for light stamping or forming operations. Its fixed TPU bumper reduces noise at the end of each cycle.
Is the Airtac ACE Compact Cylinder ACE50X55SB the Right Cylinder?
For lighter automation tasks, the ACE40X55 offers 628.3 N push at 0.5 MPa, while the ACE63X55 steps up to 1558.6 N push at the same pressure. Choose the ACE50X55SB when you need a balance of force and compact size, and ensure your air supply is filtered to 40 um and regulated within 0.15-1.0 MPa (22-145 psi). The male rod thread (B) is ideal for direct coupling to a load or tool, and the fitted magnet allows for position sensing with CMSE switches.
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 ACE50X55SB 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 operating pressure range is 0.15-1.0 MPa (22-145 psi).
The ACE50X55SB has a body that is about 50% shorter than an ISO 15552 profile cylinder, so it saves valuable mounting space. It uses a fixed TPU bumper at both ends to absorb impact, and the optional -S magnet allows CMSE or DMSE sensors to detect the piston position.
