About the Airtac ACE Compact Cylinder ACE50X15SB
This AirTAC ACE50X15SB is a double acting ISO 21287 compact cylinder that extends and retracts its rod with air pressure, delivering a 981.7 N push force at 0.5 MPa. Its short body cuts about 50% of the mounting length compared to an ISO 15552 profile cylinder, letting it fit into tight machine guards and jigs where a full-length unit will not.
The hard-anodized aluminium body and S45C hard-chrome plated rod resist wear in continuous cycling, while the fixed TPU bumper at each end absorbs impact energy. Because this model carries the optional -S magnet, you can mount CMSE or DMSE reed or solid-state switches directly on the body for position sensing. For a real-world load, plan on roughly 60 kg of safe vertical lift at 0.5 MPa, which is about 0.6 times the rated push force, leaving a margin for friction and acceleration.

Where the Airtac ACE Compact Cylinder ACE50X15SB Is Used
Fixture Clamping
Use the ACE50X15SB to clamp a small aluminum part in a CNC fixture. The 981.7 N push at 0.5 MPa holds the workpiece firmly, and the short 15 mm stroke cycles quickly for fast part changes.
Conveyor Stop Gate
Mount this cylinder on a packaging conveyor to raise a stop gate for diverting boxes. The 50 mm bore provides enough force to move the gate, and the compact body fits under the conveyor frame without protruding.
Press Plunger
In a small bench press, the ACE50X15SB can drive a plunger to insert a bushing into a housing. The 15 mm stroke delivers a controlled push, and the male rod thread lets you attach a custom press tool directly.
Is the Airtac ACE Compact Cylinder ACE50X15SB the Right Cylinder?
When sizing for a 50 mm bore, compare it with the 40 mm bore that pushes 628.3 N at 0.5 MPa if you need a lighter option, or step up to the 63 mm bore that pushes 1558.6 N for heavier work. This 15 mm stroke suits short indexing moves, and the male rod thread (B code) simplifies mounting a custom tool or fixture directly.
Since the ACE is double acting, it does not hold its position when air pressure is lost or the valve centers - the piston drifts. For a load that must stay put, add a rod lock or a pilot check valve. The 1/8" port matches standard fittings, and the optional -S magnet on this model enables CMSE / DMSE sensors for reliable end-of-stroke detection.
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 ACE50X15SB 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. These values are for the 50 mm bore with a 16 mm rod.
The ACE50X15SB has a short body that saves about 50% of the mounting length compared to an ISO 15552 profile cylinder, so it fits in tight spaces. This model includes the optional -S magnet, which allows you to mount CMSE or DMSE reed or solid-state switches for position sensing. The fixed TPU bumper at both ends absorbs end-of-stroke impact, but it does not lock or hold a load.
