Airtac ACE Compact Cylinder ACE63X70B
The AirTAC Airtac ACE Compact Cylinder ACE63X70B is a genuine double acting ISO 21287 compact air cylinder with a Ø63mm bore and 70mm 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 ACE63X70B
This AirTAC ACE63X70B is a double acting ISO 21287 compact cylinder with a 63 mm bore and a 70 mm stroke, delivering 1558.6 N of push force at 0.5 MPa. Its short body takes up about half the mounting length of an ISO 15552 profile cylinder, freeing space in tight machine frames and guarding. The male rod thread (B code) simplifies direct coupling to tooling without a rod-end adapter.
At 0.5 MPa, the usable working load is roughly 936 N (about 95 kg), so plan for that margin when sizing real parts. The fixed TPU bumper at each end absorbs impact at 30-500 mm/s, while the hard-anodized aluminium body and S45C hard-chrome rod resist wear in continuous cycling. This version has no magnet, so CMSE or DMSE sensors cannot be fitted unless you order the optional -S code.

Specifications follow the official AirTAC ACE-series (ISO 21287) datasheet. Body: hard-anodized aluminium alloy; piston rod: S45C carbon steel with hard-chrome plating. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G. A built-in magnet is OPTIONAL — add the -S code to fit CMSE / DMSE position sensors.
Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1458 N |
| 0.7 MPa | 2182 N | 2041 N |
| Max (@1.0 MPa) | 318 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac ACE Compact Cylinder ACE63X70B Is Used
Jig Clamping
Clamps sheet-metal fixtures in a stamping press with 1558.6 N push, holding parts firmly during drilling or riveting operations.
Conveyor Stop Gate
Raises a stop gate on a packaging line to divert cartons, cycling at 30-500 mm/s with the TPU bumper absorbing repeated impacts.
Machine Guard Interlock
Slides a safety guard on a CNC lathe, using the compact 70 mm stroke to fit within the machine's enclosure and the male rod for a simple bracket connection.
Is the Airtac ACE Compact Cylinder ACE63X70B the Right Cylinder?
For a lighter pick-and-place task, the ACE50X70 delivers 981.7 N push at 0.5 MPa, while stepping up to the ACE80X70 gives 2513.3 N push for heavier clamping. This 63 mm bore suits mid-range forces where a 50 mm unit is marginal but an 80 mm is oversized. Since the ACE is double acting, it extends and retracts with air, but it does not hold position if pressure drops; add a pilot check valve or rod lock for vertical loads. The 1/8" port matches common 6 mm tubing, and the male rod thread accepts standard clevis or rod-end accessories.
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 ACE63X70B FAQ
At 0.5 MPa, push is 1558.6 N and pull is 1458.1 N. At 0.7 MPa, push rises to 2182.1 N and pull to 2041.3 N. The theoretical maximum force is 317.9 kgf at 1.0 MPa.
No, this ACE63X70B has no magnet because the -S code was not ordered. CMSE or DMSE switches require the optional -S magnet, which is a separate ordering option. The fixed TPU bumper only absorbs end-of-stroke energy; it does not lock the rod in place.
