Airtac ACE Compact Cylinder ACE50X150BH
The AirTAC Airtac ACE Compact Cylinder ACE50X150BH is a genuine double acting ISO 21287 compact air cylinder with a Ø50mm bore and 150mm 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 ACE50X150BH
This AirTAC ACE50X150BH is a double acting ISO 21287 compact cylinder with a 50 mm bore and a 150 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, so it fits into tight machine frames and guarding where a full-length cylinder would not. The 16 mm hard-chrome plated S45C steel rod handles the thrust, and the fixed TPU bumper at each end absorbs end-of-stroke impact without needing adjustment.
For real-world sizing, plan for roughly 60 kg of usable vertical lift at 0.5 MPa (0.6 x 981.7 N divided by 9.81), which gives a safe margin for a 2:1 safety factor. This model has a male rod thread (B code) and a PT port thread, with no magnet fitted, so it cannot accept CMSE or DMSE sensors unless you order the optional -S magnet version. The operating pressure range is 0.15-1.0 MPa (22-145 psi), and the speed range is 30-500 mm/s, making it suitable for moderate-speed automation tasks.

Where the Airtac ACE Compact Cylinder ACE50X150BH Is Used
Jig Clamping on CNC Fixtures
Use the 981.7 N push force to clamp small to medium workpieces in a CNC milling fixture, where the compact body fits under the spindle guard and the male rod thread connects directly to a toggle clamp.
Pneumatic Stop on Assembly Line
Mount this cylinder vertically to act as a stop pin on a conveyor line, using the 881.2 N pull force to retract the rod quickly and allow parts to pass, with the TPU bumper preventing damage at high cycle rates.
Carton Ejector in Packaging Machine
In a carton erector, this cylinder pushes formed boxes out of the forming station with a 150 mm stroke, clearing the area for the next cycle, while the short body saves space in the compact packaging cell.
Is the Airtac ACE Compact Cylinder ACE50X150BH the Right Cylinder?
When selecting this ACE50X150BH, compare it with the ACE40X150 (628.3 N push at 0.5 MPa) for lighter loads or the ACE63X150 (1558.6 N push at 0.5 MPa) for heavier applications. The 150 mm stroke is within the standard 250 mm maximum for this bore, so no custom order is needed. Since this unit has no magnet, if you need position sensing, choose the ACE50X150S version with the optional -S magnet to work with CMSE or DMSE switches. For mounting, the ISO 21287 face accepts FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, or FTC brackets, and the male rod thread simplifies attachment to linkages. Remember that this cylinder does not hold its position when air pressure is lost, so for a held load, add a rod lock or pilot check valve.
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 ACE50X150BH FAQ
At 0.5 MPa, the push force is 981.7 N and the pull force is 881.2 N. At 0.7 MPa, the push force is 1374.4 N and the pull force is 1233.7 N. The theoretical maximum force is 200.2 kgf at 1.0 MPa. These figures are based on the 50 mm bore and 16 mm rod, and assume clean, filtered air.
No, this specific model (without the -S suffix) has no magnet built into the piston, so CMSE or DMSE reed or solid-state switches cannot be mounted. To use sensors, you must order the ACE50X150S version, which includes the optional -S magnet. The cylinder body has slots for the switches, but the magnet is required for them to function.
