About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X170-30S
The AirTAC SAIJ80X170-30-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers 2513N of push force and 2268N of pull force at 0.5 MPa, utilizing a 25mm carbon steel rod and PT G3/8 tapered ports. An integrated magnet enables position sensing with CMSE reed or DMSE electronic switches.
The -30 adjustment code provides a usable travel window of 140 to 170mm, allowing you to dial back the end-of-stroke position by up to 30mm. This eliminates the need to swap cylinders during product changeovers. Unlike a true locking cylinder, this rear stopper only sets the travel end; for load-holding without live air pressure, consider the SAIL or BSAI series.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X170-30S Is Used
Product Changeover
Dial in the 140-170mm travel window during packaging line format changes to accommodate varying carton sizes without swapping hardware.
Commissioning Calibration
Fine-tune the retract end-stop during initial machine setup to perfect seating pressure without machining custom spacers.
Variable End Positioning
Adjust the stroke dynamically on automated assembly equipment to hit precise retracted positions for different tooling heights.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X170-30S the Right Cylinder?
Choose this 80mm bore when 50mm (982N push @0.5MPa) is too weak or 100mm (3927N push @0.5MPa) is oversized. The adjustable 140-170mm window is ideal for machines requiring exact end-position tuning at commissioning without adding external stops, unlike a fixed-stroke SAI cylinder. It supports mounting options Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Because the 170mm stroke exceeds 300mm? No, but for any setup approaching 300mm, the 25mm rod and M20x1.5 thread handle moderate side loads, yet an external guide is recommended for heavy lateral forces. This SAIJ configuration includes a magnet (-S) for sensors, PT threaded ports, and a standard carbon steel rod.
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 SAIJ80X170-30S FAQ
At 0.5 MPa, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. It operates at speeds between 30 and 800 mm/s.
The rear adjuster screw lets you shorten the nominal 170mm stroke by up to 30mm, creating a usable travel window of 140 to 170mm. This acts as a travel stop, not a lock, so it will not hold the load without live air pressure.
