About the Airtac ACE Compact Cylinder ACE20X50B
This AirTAC ACE20X50B is a double acting ISO 21287 compact cylinder with a 20 mm bore and 50 mm stroke, delivering a 157.1 N push force at 0.5 MPa. Its short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, making it ideal for tight spaces.
The male rod thread (B code) simplifies mounting with rod-end accessories. With a fixed TPU bumper at both ends, it absorbs end-of-stroke energy; however, it does not lock or hold a load. For a 2:1 safety margin, plan to lift about 8 kg vertically with this cylinder at 0.5 MPa, not the full theoretical rating.

Where the Airtac ACE Compact Cylinder ACE20X50B Is Used
Compact Jig Clamping
Use in a small pneumatic jig for clamping thin metal parts during drilling, where the 157.1 N push force at 0.5 MPa secures parts without taking up much space.
Light Packaging Pusher
Ideal for pushing small cartons or blister packs off a conveyor into a chute, leveraging the 50 mm stroke and compact body to fit inside existing packaging machinery.
Guard Door Actuator
Mount on a machine guard or safety door to move a light interlock latch, using the short ISO 21287 body to fit within the guard frame and the male rod thread for simple linkage.
Is the Airtac ACE Compact Cylinder ACE20X50B the Right Cylinder?
For lighter applications, consider the ACE16X50 with a 100.5 N push at 0.5 MPa, or step up to the ACE25X50 for 245.4 N push. This 20 mm bore model with a 50 mm stroke suits compact automation where space is limited. Since this unit has no optional -S magnet, it cannot be used with CMSE or DMSE sensors; order the -S code if you need position sensing.
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 ACE20X50B FAQ
At 0.5 MPa, the push force is 157.1 N and the pull force is 117.8 N. At 0.7 MPa, push is 219.9 N and pull is 164.9 N. The theoretical maximum force is 32 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa (22-145 psi).
The ACE20X50B is an ISO 21287 compact cylinder, with a body about 50% shorter than an ISO 15552 profile cylinder, saving space in tight fixtures. This model has no magnet, so it cannot use CMSE or DMSE switches; you must order the -S option to get the built-in magnet for sensor mounting.
