About the Airtac ACE Compact Cylinder ACE100X50SB
This AirTAC ACE100X50SB is a double acting compact cylinder that uses air to both extend and retract its 20 mm rod, delivering a robust 3927 N push force at 0.5 MPa. Its hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder, making it ideal for tight automation cells where space is at a premium. The S code means a magnet is fitted, so you can add CMSE or DMSE switches for reliable position sensing.
With a 3769.9 N pull force at 0.5 MPa, this unit can handle substantial loads in both directions. A practical rule of thumb is to plan for about 2356 N of real work at 0.5 MPa, which translates to lifting roughly 240 kg vertically with a 2:1 safety margin. The fixed TPU bumper at each end absorbs kinetic energy, protecting the cylinder and your tooling from harsh impacts at speeds up to 500 mm/s.

Where the Airtac ACE Compact Cylinder ACE100X50SB Is Used
CNC Door Actuator
Mount this 100 mm bore cylinder to open and close the safety door on a CNC milling machine. The 3927 N push force easily overcomes door inertia, while the compact body fits within the machine's frame enclosure.
Carton Compression Test
Use the ACE100X50SB in a packaging lab to apply a controlled 3927 N force to a corrugated carton, testing its stacking strength. The fixed TPU bumper prevents jarring at the end of the stroke, ensuring consistent test results.
Press Ram for Small Parts
In a stamping or assembly line, this cylinder can act as a small press ram to insert bearings or bushings into housings. Its 50 mm stroke is enough for short press movements, and the male rod thread allows quick attachment of a custom press die.
Is the Airtac ACE Compact Cylinder ACE100X50SB the Right Cylinder?
For lighter duty in the same 100 mm bore family, consider the ACE100X25 with a shorter stroke, or step down to the ACE80X50 which offers 2513 N push at 0.5 MPa. If you need more force, the ACE125X50 provides 6135.9 N push at 0.5 MPa. This model's male rod thread (B) simplifies attachment of custom tooling, and the 1/4" port ensures adequate flow for fast cycling. Remember that this cylinder does not hold its position when air pressure is lost, so use a rod lock or pilot check valve for vertical lifting applications.
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 ACE100X50SB FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3769.9 N. At 0.7 MPa, push is 5497.8 N and pull is 5277.9 N. The theoretical maximum force is 800.9 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa (22-145 psi).
The magnet is part of the optional -S code, which this model includes. It is not standard on all ACE cylinders. With the magnet fitted, you can mount CMSE or DMSE reed or solid-state switches to detect the piston position. The compact ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder.
