Airtac ACE Compact Cylinder ACE50X15BH
The AirTAC Airtac ACE Compact Cylinder ACE50X15BH is a genuine double acting ISO 21287 compact air cylinder with a Ø50mm bore and 15mm 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 ACE50X15BH
This compact double-acting cylinder delivers 981.7 N of push force at 0.5 MPa from its 50 mm bore, with a 15 mm stroke and a 16 mm hard-chrome plated rod. The ISO 21287 body is about 50% shorter than an ISO 15552 profile cylinder, letting it fit into tight guarding and tooling envelopes where a full-length unit will not.
The hard-anodized aluminium body and S45C steel rod resist wear in high-cycle automation. With a 2:1 safety margin, this unit lifts about 50 kg vertically at 0.5 MPa (981.7 N / 9.81 / 2), giving you a practical load target for real part weights. The fixed TPU bumper at both ends absorbs end-of-stroke energy, and the male rod thread (B code) simplifies direct coupling to your tooling.

Where the Airtac ACE Compact Cylinder ACE50X15BH Is Used
Jig Clamping
Mount this 50 mm bore unit on a CNC fixture to clamp thin workpieces with 981.7 N of force at 0.5 MPa. The short 15 mm stroke and compact body fit under a guard door, and the male rod thread connects directly to a swing clamp arm.
Carton Tabbing
Use in a carton-erecting machine to push a 15 mm tab into place on a folding box. The 881.2 N retract force at 0.5 MPa pulls the tab back cleanly, while the fixed TPU bumper prevents shock at the end of each cycle.
Stop Gate
Position this cylinder on a conveyor line as a stop gate for boxes weighing up to 50 kg. The 15 mm stroke lifts a stop finger into the product path, and the compact body mounts easily on a standard ISO 21287 bracket.
Is the Airtac ACE Compact Cylinder ACE50X15BH the Right Cylinder?
For lighter indexing tasks, the 40 mm bore ACE40 delivers 628.3 N push at 0.5 MPa, while stepping up to the 63 mm bore ACE63 provides 1558.6 N for heavier clamping. This 50 mm bore unit with a 15 mm stroke suits short-travel operations where space is tight but force is still needed.
Since this model has no -S code, it has no magnet, so CMSE or DMSE sensors cannot be mounted. Order the -S variant if you need position sensing. The 1/8" port and PT thread are standard for this bore size, and the male rod thread allows direct attachment without a rod-end accessory.
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 ACE50X15BH 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. Operating pressure range is 0.15-1.0 MPa (22-145 psi), with proof pressure at 1.5 MPa (215 psi).
The ACE50X15BH body is about 50% shorter than an ISO 15552 profile cylinder, so it fits in tight spaces like machine guarding or gantry carriages. The fixed TPU bumper at both ends absorbs end-of-stroke impact, and the hard-anodized aluminium body resists wear. Note that this model has no optional -S magnet, so CMSE/DMSE sensors cannot be fitted.
