Airtac ACE Compact Cylinder ACE50X150B
The AirTAC Airtac ACE Compact Cylinder ACE50X150B is a genuine double acting ISO 21287 compact air cylinder with a Ø50mm bore and 150mm 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 ACE50X150B
This AirTAC ACE50X150B is a double acting ISO 21287 compact cylinder that extends and retracts its 16 mm rod with air pressure on both strokes. Its 50 mm bore delivers 981.7 N of push force at 0.5 MPa, making it a solid mid-range workhorse for automated assembly cells.
The hard-anodized aluminum body is about 50% shorter than an ISO 15552 profile cylinder of the same stroke, which lets it fit inside guarding and tight machine frames. The male rod thread (B code) simplifies mounting to tooling, while the fixed TPU bumper at each end absorbs impact energy. For a real-world guideline, plan for roughly 60 kg of safe working load at 0.5 MPa, which is about 60% of the theoretical rating and leaves a margin for dynamic loads.

Where the Airtac ACE Compact Cylinder ACE50X150B Is Used
Machine Guard Door Actuator
With 981.7 N push force, this cylinder reliably opens and closes a 15 kg interlocked guard door on a CNC lathe, and the compact body fits within the machine's perimeter guarding.
Conveyor Stop Gate
Mount this ACE50X150B on a packaging line to raise and lower a stop gate that diverts 10 kg cartons. The 150 mm stroke provides enough lift to clear the product flow, and the fixed bumper prevents end-of-stroke shock.
Carton Tamping Unit
Use this cylinder in a carton-erecting machine to tamp folded boxes into shape. The 881.2 N retract force pulls the tamping plate back quickly, and the short body allows installation in a confined vertical space.
Is the Airtac ACE Compact Cylinder ACE50X150B the Right Cylinder?
The ACE50X150B sits between the ACE40 and ACE63 in the compact range. If your fixture needs less than 600 N, the ACE40 with 628.3 N push at 0.5 MPa saves space and cost. For heavier clamping or pressing tasks above 1200 N, step up to the ACE63, which pushes 1558.6 N at 0.5 MPa. This 150 mm stroke version suits medium-travel applications like part transfer arms or vertical lift gates.
This model has no magnet, so it cannot trigger CMSE or DMSE sensors. If you need position sensing, order the ACE50X150SB variant with the optional -S magnet. The 1/8" port and male rod thread are ready for standard fittings and rod-end accessories.
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 ACE50X150B FAQ
At 0.5 MPa, this cylinder produces 981.7 N push and 881.2 N pull. At 0.7 MPa, it produces 1374.4 N push and 1233.7 N pull. 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).
The ACE50X150B's body is about 50% shorter than an ISO 15552 profile cylinder, so it fits in tight spaces behind panels or inside machine frames. It uses a fixed TPU bumper for end-of-stroke deceleration, not an adjustable cushion. The optional -S magnet (not on this model) is required for CMSE or DMSE sensors.
