Airtac ACE Compact Cylinder ACE63X20S
The AirTAC Airtac ACE Compact Cylinder ACE63X20S is a genuine double acting ISO 21287 compact air cylinder with a Ø63mm bore and 20mm 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 ACE63X20S
This AirTAC ACE63X20S is a double acting ISO 21287 compact cylinder that extends and retracts its 16 mm rod with air pressure. The 63 mm bore generates 1558.6 N of push force and 1458.1 N of pull force at 0.5 MPa, so it suits medium-duty automation tasks.
The hard-anodized aluminium body is about 50% shorter than an ISO 15552 profile cylinder, saving valuable space in tight machine frames. A fixed TPU bumper at each end absorbs impact, and the optional -S magnet is fitted here, enabling CMSE or DMSE switches for position sensing. For a safe working load, plan for roughly 935 N of real work at 0.5 MPa, which equals lifting about 95 kg vertically with a 2:1 safety margin.

Where the Airtac ACE Compact Cylinder ACE63X20S Is Used
Fixture Clamping
Use the ACE63X20S to clamp a workpiece in a CNC milling fixture. Its 1558.6 N push force holds parts securely, while the short body fits under a machine guard.
Package Stops
Mount this cylinder on a packaging conveyor to raise a stop gate. The 20 mm stroke is enough to block cartons, and the 1458.1 N pull force retracts the gate quickly.
Press Ram
In a small assembly press, the ACE63X20S pushes a stamping die with 2182.1 N at 0.7 MPa. The compact body lets you install it in a benchtop frame with minimal clearance.
Is the Airtac ACE Compact Cylinder ACE63X20S the Right Cylinder?
Choose the ACE63X20S when you need a compact cylinder with a 20 mm stroke and a 63 mm bore. Compare it with the ACE50X20S, which pushes 981.7 N at 0.5 MPa, or the ACE80X20S, which pushes 2513.3 N, to match your force requirement. This model uses a 1/8" port and has a female M10x1.5 rod thread, fitting standard ISO 21287 mounts like FA, LB, or CA brackets.
Because the magnet is fitted, you can add CMSE or DMSE switches for end-of-stroke detection. Remember that a plain ACE does not hold its position when air is removed; use a rod lock or pilot check valve for load holding. The fixed TPU bumper only softens end-of-stroke impact, not a braking function.
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 ACE63X20S FAQ
At 0.5 MPa, the push force is 1558.6 N and the pull force is 1458.1 N. At 0.7 MPa, push is 2182.1 N and pull is 2041.3 N. The theoretical maximum force is 317.9 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa (22-145 psi).
It is an ISO 21287 compact cylinder with a hard-anodized aluminium body that is about 50% shorter than an ISO 15552 profile cylinder. It has a fixed TPU bumper at both ends to absorb impact, not an adjustable cushion. The bumper does not lock or hold a load; for that, use a rod lock or pilot check valve.
