About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX60-50S
The AirTAC SAIJ80X60-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the travel. With a nominal 60 mm stroke and a 50 mm adjustment range, it provides a highly versatile 10 to 60 mm usable travel window. This wide tuning band is perfect for prototyping or production lines where the exact end-position changes between product runs. At 0.5 MPa, this 80 mm bore generates 2513 N of push force and 2268 N of pull force.
This specific configuration uses a SUS304 stainless steel rod (code B) for superior corrosion resistance in harsher environments. The barrel is an extruded aluminum profile with sensor grooves on both sides, and because this is an -S model, it includes a magnet ready for AirTAC CMSE reed and DMSE electronic sensors. The rear adjuster acts purely as a mechanical stop to set the travel end, working alongside the variable air cushions at both ends to decelerate the load.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX60-50S Is Used
Machine Changeover
Dial in the exact end-stop for new product dimensions during line changeovers without disassembling the pneumatic setup.
Prototype Positioning
Fine-tune the 10 to 60 mm travel window during equipment commissioning to find the optimal operating distance.
Variable End Stops
Handle multiple product sizes on a single conveyor line by adjusting the rear stopper screw to the required travel distance.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX60-50S the Right Cylinder?
Choose this 80 mm bore if your application requires more force than the 63 mm class (which provides 1559 N push at 0.5 MPa) but you want to avoid the bulk of a 100 mm cylinder. The 50 mm adjustment range on a 60 mm stroke is particularly useful when you need to vary the end-stop for different product sizes without swapping out the entire cylinder or adding external stops. For load-holding without live air pressure, note that this adjuster is a stop and not a lock; you would need an external pilot-operated check valve or a related SAIL lock cylinder.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 60 mm stroke, PT tapered G3/8 port, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR mounts found on some other series.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ80 Adjustable Cylinder SAIJ80BX60-50S FAQ
The rear adjuster screw lets you mechanically shorten the stroke by up to 50 mm. This turns the 60 mm nominal stroke into a usable 10 to 60 mm travel window, allowing you to set the exact end-position without adding external stops.
It delivers 2513 N of push force and 2268 N of pull force at 0.5 MPa. The standard operating speed ranges from 30 to 800 mm/s, driven by a G3/8 port and a 25 mm rod.
