Airtac ACE Compact Cylinder ACE63X250SCB
The AirTAC Airtac ACE Compact Cylinder ACE63X250SCB is a genuine double acting ISO 21287 compact air cylinder with a Ø63mm bore and 250mm 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 ACE63X250SCB
This AirTAC ACE63X250SCB is a double acting compact cylinder built to ISO 21287, with a 63 mm bore and a 250 mm stroke. 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 unit will not. The S45C piston rod is hard-chrome plated for wear resistance, and the fixed TPU bumper at each end absorbs end-of-stroke impact.
At 0.5 MPa this unit delivers 1558.6 N of push force and 1458.1 N of pull force. For a real-world estimate, plan on about 935 N of usable work at that pressure, which translates to lifting roughly 95 kg vertically with a 2:1 safety margin. The optional -S magnet is fitted on this model, so you can mount CMSE or DMSE reed and solid-state switches directly to the body for position sensing.

Where the Airtac ACE Compact Cylinder ACE63X250SCB Is Used
Press Ram for Small Stamping Dies
Use the 1558.6 N push force at 0.5 MPa to drive a small stamping or piercing die in a benchtop press. The compact body fits under a die set where a profile cylinder would not clear, and the fixed TPU bumper protects the tooling at the end of each stroke.
Carton Tamping on a Packing Line
Mount this cylinder with a CB clevis to tamp or square cardboard cartons before taping. The 250 mm stroke covers a range of box heights, and the 1458.1 N pull force retracts the tamping plate quickly to keep the line moving at speeds up to 500 mm/s.
Fixture Clamp for Machining Center
In a CNC machining center, use this cylinder to clamp a workpiece against a fixed stop. The 63 mm bore provides enough force to hold a mid-size part securely, while the short body leaves room for chip guards and coolant nozzles. The optional -S magnet lets a CMSE switch confirm the clamp is engaged.
Is the Airtac ACE Compact Cylinder ACE63X250SCB the Right Cylinder?
When sizing an ACE63X250SCB, compare it against the ACE50X250, which produces 981.7 N push at 0.5 MPa, or the ACE80X250, which pushes 2513.3 N at the same pressure. This 63 mm bore sits in the middle, offering a strong balance of force and compactness. The 250 mm stroke is the maximum standard for this bore, so it is a made-to-order option if you need longer travel. Since this is a double acting cylinder, it will not hold its position if air pressure is lost; for a held load, add a rod lock or pilot check valve. The 1/8" port and M10x1.5 female rod thread match standard ISO 21287 accessories, and the CB clevis mounting bracket bolts directly to the body face.
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 ACE63X250SCB 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 rises to 2182.1 N and pull to 2041.3 N. The theoretical maximum force at 1.0 MPa is 317.9 kgf. The operating pressure range is 0.15-1.0 MPa (22-145 psi), and the proof pressure is 1.5 MPa (215 psi).
The ACE63X250SCB has a hard-anodized aluminium body that is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight spaces like machine guarding or gantries. It has a fixed TPU bumper at both ends to absorb impact, and the optional -S magnet on this model allows CMSE or DMSE switches to detect the piston position. The 1/8" port and M10x1.5 rod thread are standard for this bore size.
