Airtac ACE Compact Cylinder ACE50X80SB
The AirTAC Airtac ACE Compact Cylinder ACE50X80SB is a genuine double acting ISO 21287 compact air cylinder with a Ø50mm bore and 80mm 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 ACE50X80SB
This AirTAC ACE50X80SB is a double acting ISO 21287 compact cylinder, delivering 981.7 N of push force at 0.5 MPa. 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 16 mm hard-chrome plated rod and fixed TPU bumpers handle the 80 mm stroke with a speed range of 30-500 mm/s.
With the optional -S magnet already fitted, this model works with CMSE or DMSE reed and solid-state switches for reliable position sensing. For real-world sizing, plan for about 60 kg of safe working load at 0.5 MPa, which is roughly 0.6 times the push rating, leaving a margin for friction and acceleration. The male rod thread (B code) simplifies direct coupling to your tooling without extra adapters.

Where the Airtac ACE Compact Cylinder ACE50X80SB Is Used
Fixture Clamping in CNC
Use the 981.7 N push at 0.5 MPa to clamp a 50 mm thick steel workpiece in a CNC milling vise. The compact body fits under the spindle guard, and the 80 mm stroke retracts the clamp fully clear for part loading.
Pneumatic Stop on Conveyor
Mount this cylinder on a roller conveyor to raise a stop pin that halts totes weighing up to 60 kg. The 80 mm stroke lifts the pin high enough to clear the tote bottom, and the optional magnet signals the PLC when the pin is up.
Carton Tucking Station
In a packaging line, this cylinder pushes a folded carton flap into place before sealing. The 881.2 N pull retracts the tucker arm quickly, and the fixed TPU bumper prevents jarring at the end of the 80 mm stroke, protecting the carton.
Is the Airtac ACE Compact Cylinder ACE50X80SB the Right Cylinder?
Choose this ACE50X80SB when you need a compact 50 mm bore cylinder that pushes 981.7 N and pulls 881.2 N at 0.5 MPa. If your application requires less force, the ACE40X80 offers 628.3 N push, while stepping up to the ACE63X80 gives 1558.6 N push at the same pressure. The 80 mm stroke is within the 250 mm standard maximum for this bore, so no special order is needed.
Because this unit has the -S magnet, it is ready for CMSE or DMSE sensors, making it ideal for automated cycles that need end-position feedback. The male rod thread lets you bolt on a clevis or rod end directly. Remember, this cylinder does not hold its load if air pressure is lost, so for vertical lifting with a hanging load, add a rod lock or pilot check valve.
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 ACE50X80SB 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. These values assume clean, dry air at the rated pressure.
The ACE50X80SB body is about 50% shorter than an ISO 15552 profile cylinder of the same bore and stroke, so it fits into tight spaces like robotic end-of-arm tooling or inside machine guards. It uses a fixed TPU bumper at both ends for smooth deceleration, not an adjustable air cushion. The optional -S magnet enables CMSE or DMSE sensors for position feedback.
