Airtac SAIJ80 Adjustable Cylinder SAIJ80X170-30
The AirTAC Airtac SAIJ80 Adjustable Cylinder SAIJ80X170-30 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 170mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X170-30
The AirTAC SAIJ80X170-30 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers 2513 N of push force at 0.5 MPa and 4523 N at 0.9 MPa, making it suited for medium to heavy pneumatic tasks. The built-in adjustment screw provides a usable travel window of 140 to 170 mm, allowing you to dial back the nominal stroke by up to 30 mm during commissioning.
This adjustable stopper lets you fine-tune the retract end position on product changeovers without swapping the cylinder or adding external stops. It uses a carbon steel piston rod with an M20x1.5 thread, and the extruded aluminum barrel includes sensor grooves on both sides. The rear adjuster acts strictly as a travel stop and deceleration aid alongside the dual air cushions, not as a lock, so it will not hold a load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X170-30 Is Used
End-Position Tuning
Dial in the exact retract distance within a 140-170 mm window during machine setup without physically adding external spacers or stopper blocks.
Product Changeover
Quickly adjust the stroke end-stop on a conveyor line when product sizes change, saving downtime by avoiding cylinder removal.
Fixture Clamping
Provide up to 4523 N of clamping force at 0.9 MPa while fine-tuning the exact clamping depth to protect delicate workpieces.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X170-30 the Right Cylinder?
Choose this 80 mm bore cylinder when your application requires a 2513 N pull force at 0.5 MPa and a variable end-stop within a 140 to 170 mm travel range. If your force requirements are lower, stepping down to a 63 mm bore yields 1402 N of pull force, whereas moving up to a 100 mm bore provides 3681 N of pull force. The SAIJ80X170-30 is dimensionally interchangeable per ISO 15552, featuring a PT tapered G3/8 port, a carbon steel rod, and standard double-acting operation without a magnet.
Because the rear adjuster only sets the travel end and cannot hold a load without continuous air pressure, you should select the SAIL or BSAI series if your machine requires true fail-safe load holding. The SAIJ mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets. For this 170 mm stroke, the 25 mm rod handles standard side loads well, but long unsupported strokes still require an external guide.

- ✓ 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 SAIJ80X170-30 FAQ
At 0.5 MPa it provides 2513 N of push force and 2268 N of pull force. At 0.9 MPa, the push force increases to 4523 N.
The rear adjuster screw lets you shorten the effective travel from the nominal 170 mm down to 140 mm, giving a 140-170 mm usable window. It acts as a travel stop and does not lock the load without live air pressure.
