Airtac ACE Compact Cylinder ACE50X75SB
The AirTAC Airtac ACE Compact Cylinder ACE50X75SB is a genuine double acting ISO 21287 compact air cylinder with a Ø50mm bore and 75mm 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 ACE50X75SB
This AirTAC ACE50X75SB is a double acting compact cylinder built to ISO 21287, with a hard-anodized aluminium body that is about 50% shorter than an ISO 15552 profile cylinder. It delivers 981.7 N of push force at 0.5 MPa, so it fits into tight automation cells where a full-length cylinder would not.
With the optional -S magnet already fitted, this model works with CMSE or DMSE reed and solid-state switches for reliable position sensing. The S45C hard-chrome rod and fixed TPU bumpers handle the 75 mm stroke at speeds from 30 to 500 mm/s, and the 1/8" port keeps plumbing simple. For real work, plan on about 589 N of usable force at 0.5 MPa, which lifts roughly 60 kg vertically with a 2:1 safety margin.

Where the Airtac ACE Compact Cylinder ACE50X75SB Is Used
Fixture Clamping
Use the 981.7 N push at 0.5 MPa to clamp sheet-metal parts in a welding jig, where the short ISO 21287 body clears the robot arm path.
Carton Pusher
Push 75 mm stroke to index cartons on a packaging conveyor, with the 881.2 N pull retracting the rod for the next cycle.
Sorting Gate
Divert products on a sorting line with the fitted -S magnet triggering a CMSE switch at each end, confirming gate position.
Is the Airtac ACE Compact Cylinder ACE50X75SB the Right Cylinder?
Choose this 50 mm bore when you need a mid-range force of 981.7 N push and 881.2 N pull at 0.5 MPa. If your load is lighter, a 40 mm bore gives 628.3 N push, while stepping up to a 63 mm bore provides 1558.6 N push for heavier tasks.
The male rod thread (B) simplifies mounting with rod-end accessories, and the ISO 21287 face accepts FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, or FTC brackets. Since the magnet is fitted, you can add CMSE or DMSE switches for end-of-stroke detection, but note this cylinder does not hold position when air is lost - use a rod lock or pilot check valve for that.
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 ACE50X75SB FAQ
At 0.5 MPa, push is 981.7 N and pull is 881.2 N. At 0.7 MPa, push is 1374.4 N and pull is 1233.7 N. The theoretical maximum force is 200.2 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi).
It follows ISO 21287, so the body is about 50% shorter than an ISO 15552 profile cylinder, saving space in tight machines. It has a fixed TPU bumper at both ends for deceleration, and the optional -S magnet enables CMSE or DMSE switches for position sensing.
