About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X170-10
The AirTAC SAIJ80X170-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 160 to 170 mm, allowing you to dial in the retract end position precisely during commissioning without adding external stops. In the 80 mm bore class, it delivers 2513 N of push force and 2268 N of pull force at a 0.5 MPa operating pressure.
This unit uses a standard carbon steel piston rod and a PT tapered G3/8 port. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed and DMSE electronic sensors. The rear adjuster acts purely as a mechanical stop to set the travel limit and does not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X170-10 Is Used
End-Position Tuning
Dial in the exact 160 to 170 mm retract position during machine commissioning to perfect product handling without swapping cylinders.
Product Changeover
Quickly adjust the stroke stop on a packaging line when running a slightly shorter product format, minimizing downtime between batches.
Machining Clamps
Fine-tune the clamping reach on a machining fixture, using the 25 mm rod and M20x1.5 thread to handle high side loads securely.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X170-10 the Right Cylinder?
Choose this 80 mm bore cylinder when your application requires the 2513 N push force at 0.5 MPa, stepping up from the 63 mm bore which provides 1559 N. The 10 mm adjustment range is ideal for fine-tuning end positions during machine setup or product changeover, whereas a fixed-stroke SAI cylinder locks you into a single exact dimension. For strokes of 170 mm, side-load risks are moderate, but an external guide is recommended if the load is unsupported.
To match this ISO 15552 interchangeable cylinder, specify: 80 mm bore, 170 mm stroke, 10 mm adjustment, PT G3/8 port, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mountings. It does not use FB, CA, CB, or CR mounts. Since it lacks a lock, use SAIL or BSAI cylinders if you need fail-safe load holding without continuous air pressure.
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 SAIJ80X170-10 FAQ
At a 0.5 MPa operating pressure, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 513 kgf.
The rear adjuster screw acts as a mechanical stop, letting you shorten the 170 mm nominal stroke by up to 10 mm, creating a 160 to 170 mm usable travel window. It only sets the end position and does not lock the load without live air pressure.
