Airtac ACE Compact Cylinder ACE50X5SB
The AirTAC Airtac ACE Compact Cylinder ACE50X5SB is a genuine double acting ISO 21287 compact air cylinder with a Ø50mm bore and 5mm 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 ACE50X5SB
This AirTAC ACE50X5SB is a double acting ISO 21287 compact cylinder that extends and retracts its 16 mm rod with air pressure on both strokes. At 0.5 MPa it delivers 981.7 N of push force, enough to drive a small press or clamp a fixture firmly, and its 5 mm stroke suits short indexing moves.
The body is hard-anodized aluminium and about 50% shorter than an ISO 15552 profile cylinder, so it fits inside tight machine guards where a full-length unit will not. The -S code means the optional magnet is fitted, so CMSE or DMSE reed and solid-state switches can sense the piston position. For a real workload, plan on about 60 kg of usable force at 0.5 MPa, which is roughly 0.6 times the rated push, giving a safe margin for friction and side loads.

Where the Airtac ACE Compact Cylinder ACE50X5SB Is Used
Short-Stroke Press
Use the ACE50X5SB in a benchtop arbor press to stamp small metal tags or emboss plastic parts, with the 5 mm stroke providing precise, repeatable depth control.
Part Ejector
Mount it on a packaging conveyor to push finished cartons off the line at a right angle. The 981.7 N push at 0.5 MPa clears even heavy boxes, and the compact body fits under the belt frame.
Clamping Fixture
In a CNC machining cell, this cylinder can clamp a workpiece against a stop during drilling. The short stroke reduces cycle time, and the optional magnet lets a CMSE switch confirm the clamp is engaged.
Is the Airtac ACE Compact Cylinder ACE50X5SB the Right Cylinder?
For a lighter duty, the ACE32X25 offers 402.1 N push at 0.5 MPa, while the ACE63X10 steps up to 1558.6 N push. This 50 mm bore with a 5 mm stroke is ideal for short, repetitive actions like part ejection or valve actuation, and the male rod thread (B) lets you bolt on a custom tool directly. The fixed TPU bumper absorbs end-of-stroke impact, but it does not hold a load if air pressure drops, so add a rod lock or pilot check valve if you need position holding. 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 ACE50X5SB FAQ
At 0.5 MPa, push force is 981.7 N and 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 are for the 50 mm bore with a 16 mm rod.
It follows ISO 21287, so its body is about 50% shorter than an ISO 15552 profile cylinder, saving space in tight machinery. The fixed TPU bumper at each end absorbs impact at stroke end, but it is not an adjustable cushion and does not lock the rod in place. For holding a load, use a separate rod lock or pilot check valve.
