About the Airtac ACE Compact Cylinder ACE50X175S
This AirTAC ACE50X175S is a double acting compact cylinder that delivers 981.7 N of push force at 0.5 MPa, with a pull force of 881.2 N on the retract stroke. Its ISO 21287 short body takes up about 50% less mounting length than an ISO 15552 profile cylinder, making it a strong fit for tight machine frames and guard enclosures.
The 50 mm bore version has a 16 mm hard-chrome plated S45C steel rod and a 1/8" port, with a fixed TPU bumper at both ends to absorb impact. The optional -S magnet is fitted on this model, so you can mount CMSE or DMSE reed or solid-state switches for position sensing. For a real-world load, plan on about 60 kg of safe vertical lift at 0.5 MPa, which is roughly 0.6 times the rated push force, giving you a comfortable margin for jigs or parts.

Where the Airtac ACE Compact Cylinder ACE50X175S Is Used
Fixture Clamping
Use the ACE50X175S to clamp sheet metal parts in a CNC milling fixture. The 981.7 N push force at 0.5 MPa holds the workpiece firmly, while the compact body fits between the machine table and the spindle guard.
Sorting Gate
Mount this cylinder on a packaging conveyor to operate a diverting gate. The 175 mm stroke moves the gate across the belt path, and the 881.2 N pull force retracts it quickly, keeping up with 30-500 mm/s cycle speeds.
Pallet Stops
In an automated warehouse, this cylinder can raise or lower a pallet stop on a roller conveyor. The 50 mm bore provides enough force to hold a loaded pallet, and the fixed TPU bumper reduces noise at the end of each stroke.
Is the Airtac ACE Compact Cylinder ACE50X175S the Right Cylinder?
When sizing, compare this 50 mm bore with the 40 mm bore that pushes 628.3 N at 0.5 MPa, or step up to the 63 mm bore that pushes 1558.6 N at the same pressure. The 175 mm stroke is within the 250 mm maximum standard stroke for this bore, so it ships as a standard unit without long lead times. Since this model has the -S magnet, you can add CMSE or DMSE switches for end-of-stroke detection; if you need a male rod thread, order the B option instead of the blank female M10x1.5 thread. Mounting options include FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, or FTC brackets, all of which bolt directly to the ISO 21287 face. Remember, this cylinder does not hold its position when air pressure is lost, so for a held load use 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 ACE50X175S 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 numbers assume a perfectly dry air supply filtered to 40 um.
The ACE50X175S has a short, hard-anodized aluminium body that saves about 50% of the mounting length compared to an ISO 15552 profile cylinder. This lets you fit it into machine guards, gantries, or tool changers where a longer cylinder would not fit. The fixed TPU bumper at both ends absorbs end-of-stroke impact, and the optional -S magnet allows CMSE or DMSE sensors to detect the piston position.
