About the Airtac ACE Compact Cylinder ACE50X55B
This AirTAC ACE50X55B is a double acting ISO 21287 compact cylinder that delivers a 981.7 N push and 881.2 N pull at 0.5 MPa, with a theoretical maximum of 200.2 kgf at 1.0 MPa. Its short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, making it a space-saving choice for tight machine frames and guarding.
The hard-anodized aluminium body and S45C hard-chrome plated rod resist wear in continuous cycling. This model has a male rod thread (B code) and no magnet, so it cannot accept CMSE or DMSE sensors unless you order the optional -S version. For a 2:1 safety margin, plan to lift about 30 kg vertically at 0.5 MPa, not the full rated force.

Where the Airtac ACE Compact Cylinder ACE50X55B Is Used
Fixture Clamping
Use the 981.7 N push force to clamp sheet metal parts in a CNC machining fixture, holding them securely during drilling operations.
Package Stops
Mount this cylinder on a packaging line to raise a stop gate that diverts boxes weighing up to 30 kg, with the 55 mm stroke providing quick clearance.
Press Ram
In a small benchtop press, this cylinder's 881.2 N pull force retracts a forming die after each cycle, enabling semi-automated assembly of electronic components.
Is the Airtac ACE Compact Cylinder ACE50X55B the Right Cylinder?
For lighter duty, 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 this 50 mm bore when you need a balance of force and compactness for medium-sized automation tasks. Since this unit has no magnet, order the -S code if you need position sensing with CMSE or DMSE 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 ACE50X55B 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.
It follows ISO 21287, so its body is about 50% shorter than an ISO 15552 profile cylinder. This saves mounting space in tight fixtures. It has a fixed TPU bumper at both ends to absorb impact, but it does not lock or hold a load; use a rod lock or pilot check valve for that.
