About the Airtac ACE Compact Cylinder ACE50X45S
This AirTAC ACE50X45S is a double acting compact cylinder that delivers a 981.7 N push force at 0.5 MPa, making it a solid choice for mid-range automation tasks. Its ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits into tight machine frames and guarding where a longer cylinder will not.
With the optional -S magnet already fitted, this model works with CMSE or DMSE reed and solid-state switches for reliable position sensing. At 0.5 MPa, the pull force is 881.2 N, and a practical rule of thumb is to plan for about 589 N of real work, which translates to lifting roughly 60 kg vertically with a 2:1 safety margin.

Where the Airtac ACE Compact Cylinder ACE50X45S Is Used
Jig Clamping on CNC
Mount this compact cylinder to a CNC fixture to clamp small aluminum parts during drilling. The 45 mm stroke is ideal for quick clamp release, and the short body keeps the fixture profile low.
Conveyor Stop Gate
Use the ACE50X45S as a stop gate on a packaging conveyor line. Its 981.7 N push at 0.5 MPa can gently halt cartons, and the optional magnet lets a sensor confirm the gate position.
Pallet Strap Tensioner
In a warehouse strapping station, this cylinder can tension a plastic strap around a pallet load. The 45 mm stroke provides enough travel to pull the strap tight before sealing.
Is the Airtac ACE Compact Cylinder ACE50X45S the Right Cylinder?
For a lighter duty, the ACE40X45 offers a 628.3 N push at 0.5 MPa, while stepping up to the ACE63X45 gives you 1558.6 N push at the same pressure. This 50 mm bore version balances force and size for applications like clamping or light pressing. The 1/8" port is standard for this bore, and the female rod thread is M10x1.5. Remember, this cylinder does not hold its position when air is lost; use a rod lock or pilot check valve if load holding is critical. Mounting options include FA/FB flange, LB foot, CA/CB clevis, and SDB pivot brackets.
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 ACE50X45S 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 at 1.0 MPa is 200.2 kgf.
The short body saves about 50% of the mounting length compared to an ISO 15552 profile cylinder, letting you fit it into tight spaces. It has a fixed TPU bumper at both ends to absorb impact, and the optional -S magnet allows CMSE or DMSE sensors to detect the piston position.
