Airtac ACE Compact Cylinder ACE50X225SB
The AirTAC Airtac ACE Compact Cylinder ACE50X225SB is a genuine double acting ISO 21287 compact air cylinder with a Ø50mm bore and 225mm 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 ACE50X225SB
This AirTAC ACE50X225SB is a double acting compact cylinder that extends and retracts its 16 mm rod with air pressure. It delivers 981.7 N of push force and 881.2 N of pull force at 0.5 MPa, making it a solid mid-range workhorse for automated assembly. The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it slips into tight guarding and compact jigs where a full-length cylinder will not fit. A built-in TPU bumper at each end absorbs impact energy, and the hard-anodized aluminium body with a hard-chrome plated S45C steel rod resists wear in continuous cycling.
For real-world sizing, plan for about 60 kg of safe working load at 0.5 MPa (0.6 times the 981.7 N rating), which gives you a comfortable margin for dynamic loads and acceleration. This model carries the optional -S magnet, so you can mount CMSE or DMSE reed or solid-state switches directly on the body to confirm rod position. The male rod thread (B code) simplifies mounting to your tooling, and the 1/8" port matches common air prep components in this force class.

Where the Airtac ACE Compact Cylinder ACE50X225SB Is Used
Fixture Clamping on CNC
Mount this ACE50X225SB on a CNC fixture to clamp medium-sized workpieces with 981.7 N of force at 0.5 MPa. The compact body fits under guarding, and the male rod thread connects directly to a custom clamp arm.
Parcel Divert on Conveyor
Use the 225 mm stroke to push parcels off a conveyor line onto a sorting chute. The 881.2 N pull force retracts the rod quickly, and the optional -S magnet lets you confirm the paddle position with a CMSE switch.
Carton Ejection in Packaging
In a carton erecting machine, this cylinder ejects folded boxes from a magazine. The 50 mm bore delivers enough thrust to overcome friction, while the TPU bumper prevents end-of-stroke shock that could damage light packaging.
Is the Airtac ACE Compact Cylinder ACE50X225SB the Right Cylinder?
When selecting between bores, compare this 50 mm bore against a 40 mm bore that pushes 628.3 N at 0.5 MPa or a 63 mm bore that pushes 1558.6 N. The 50 mm bore offers a balanced middle ground for medium-duty pushes, while the 63 mm gives roughly 60% more force if your application demands it. For this 225 mm stroke, verify that the available mounting space accommodates the full extension, and remember that a plain ACE cylinder does not hold its position when air is lost - use a rod lock or pilot check valve if you need to hold a load in place. The optional -S magnet is already fitted here, so you can add CMSE or DMSE switches for position sensing without any modification.
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 ACE50X225SB 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 rises to 1374.4 N and pull to 1233.7 N. The theoretical maximum force is 200.2 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa (22-145 psi), and the proof pressure is 1.5 MPa (215 psi).
The ACE50X225SB has a short body that saves about 50% of the mounting length compared to an ISO 15552 profile cylinder, so it fits in tight spaces. It uses a fixed TPU bumper at both ends to absorb impact, and the optional -S magnet allows CMSE or DMSE switches for position sensing. The body is hard-anodized aluminium with a hard-chrome plated steel rod for durability.
