About the Airtac ACE Compact Cylinder ACE50X150SB
This AirTAC ACE50X150SB is a double acting compact cylinder that delivers 981.7 N of push force and 881.2 N of pull force at 0.5 MPa, with a theoretical maximum of 200.2 kgf at 1.0 MPa. Its ISO 21287 short body takes up about 50% less mounting length than an ISO 15552 profile cylinder, making it a smart fit for tight automation cells and guarding where space is at a premium.
The hard-anodized aluminium body and S45C hard-chrome plated rod are built for repeated cycling in dusty shop-floor air. The fixed TPU bumper at each end absorbs impact energy, and the optional -S magnet is fitted here, so you can add CMSE or DMSE reed or solid-state switches for position sensing. As a sizing rule, plan for a safe working load of about 589 N at 0.5 MPa, which means it can lift roughly 60 kg vertically with a 2:1 safety margin.

Where the Airtac ACE Compact Cylinder ACE50X150SB Is Used
Fixture Clamping
Use the 981.7 N push force to clamp sheet metal parts in a welding jig, where the short body fits between locating pins and the 150 mm stroke clears the part for loading.
Sorting Pusher
On a packaging conveyor, this cylinder can push cartons off a side rail. The 881.2 N pull retracts quickly to handle cycle rates up to 500 mm/s.
Guard Door Actuator
In a CNC machine enclosure, the compact body mounts behind a safety guard, using the 150 mm stroke to slide the door open and closed with a firm 981.7 N push.
Is the Airtac ACE Compact Cylinder ACE50X150SB the Right Cylinder?
When sizing this ACE50X150SB, compare it against the ACE40X150 which pushes 628.3 N at 0.5 MPa for lighter duty, or step up to the ACE63X150 that delivers 1558.6 N at 0.5 MPa if your fixture needs more force. At 0.5 MPa, the 50 mm bore provides a good balance of thrust and compactness for medium-sized clamping or pushing tasks.
Because this model carries the -S magnet, you can mount CMSE or DMSE sensors directly to track the rod position. The male rod thread (B) simplifies attaching custom tooling. Remember, this cylinder does not hold its position if air pressure is lost, so for vertical lifting or load holding, add a rod lock or a pilot check valve in your circuit.
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 ACE50X150SB 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 port size is 1/8 inch, and the rod is 16 mm with a male thread.
The ACE50X150SB has a short body that saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits into tight spaces like guard panels or between machine frames. It uses a fixed TPU bumper at both ends to absorb impact, and the optional -S magnet allows CMSE or DMSE sensors to detect the piston position.
