Airtac ACE Compact Cylinder ACE50X70
The AirTAC Airtac ACE Compact Cylinder ACE50X70 is a genuine double acting ISO 21287 compact air cylinder with a Ø50mm 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 ACE50X70
This AirTAC ACE50X70 is a double acting compact cylinder built to ISO 21287, with a 50 mm bore and a 70 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 cylinder will not. The S45C steel rod is hard-chrome plated for wear resistance, and a fixed TPU bumper at each end absorbs end-of-stroke energy.
At 0.5 MPa this unit pushes with 981.7 N and pulls with 881.2 N, so a practical safe working load is about 589 N - enough to lift roughly 60 kg vertically with a 2:1 safety margin. The 1/8" port keeps installation simple, and the optional -S magnet (not fitted here) is required before any CMSE or DMSE sensor can be mounted. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a proof pressure of 1.5 MPa (215 psi), and speed ranges from 30 to 500 mm/s.

Where the Airtac ACE Compact Cylinder ACE50X70 Is Used
Jig Clamping on Machining Center
Clamp a 50 mm fixture plate in a CNC machining center with a 70 mm stroke, using the 981.7 N push to hold parts firmly during drilling or milling operations.
Package Stop on Conveyor Line
Act as a stop gate on a packaging conveyor, extending 70 mm to block cartons weighing up to 60 kg, with the compact body fitting under the conveyor frame.
Carton Ejector in Palletizer
Push finished cartons off a palletizing station with a 70 mm stroke, using the 881.2 N pull force to retract quickly and clear the next cycle.
Is the Airtac ACE Compact Cylinder ACE50X70 the Right Cylinder?
For lighter indexing or clamping tasks, the ACE40X70 offers 628.3 N push at 0.5 MPa, while the ACE63X70 steps up to 1558.6 N push if you need more force. This ACE50X70 with 981.7 N push suits medium-duty applications where a 70 mm stroke is enough. Remember that this plain double acting cylinder does not hold position when air is removed - for a held load, add a rod lock or pilot check valve. The body has magnet slots, but since this model has no -S code, there is no magnet fitted; order the -S version to enable CMSE or DMSE switches. Mounting options include FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, and FTC brackets, all matching the ISO 21287 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 ACE50X70 FAQ
At 0.5 MPa, push is 981.7 N and pull 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 rod is 16 mm with an M10x1.5 female thread, and the port is 1/8" PT.
The ACE50X70 follows ISO 21287, a compact standard that saves about 50% of the mounting length compared to an ISO 15552 profile cylinder. This lets it fit into tight spaces. It uses a fixed TPU bumper at both ends to absorb impact, not an adjustable cushion. The optional -S magnet is needed for CMSE or DMSE sensors, and it is not fitted on this model.
