Airtac SAIJ80 Adjustable Cylinder SAIJ80X170-75
The AirTAC Airtac SAIJ80 Adjustable Cylinder SAIJ80X170-75 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 SAIJ80X170-75
The AirTAC SAIJ80X170-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a robust 2513N push force at 0.5 MPa. By integrating a 75mm adjustment mechanism at the rear, this unit allows operators to dial back the 170mm nominal stroke, creating a usable travel window between 95mm and 170mm without needing external stops. It features a 25mm carbon steel piston rod and a PT tapered G3/8 port for reliable pneumatic flow.
This adjustable-stroke design is ideal for fine end-position tuning during commissioning or product changeovers. The rear screw acts purely as a mechanical stop to set the travel end and relies on the integrated variable air cushion for deceleration; it does not hold the load without live air pressure. For position-holding requirements without continuous air, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X170-75 Is Used
Machine Changeovers
Quickly adapt the cylinder's 95-170mm travel window during product size transitions on a packaging line without swapping out the entire actuator.
End-Position Tuning
Fine-tune the retract stroke during initial commissioning to achieve precise mechanical stops for high-accuracy assembly tasks.
Variable End Stops
Dial in the exact 170mm nominal stroke reduction needed for multi-stage processes, using the rear adjuster to set distinct operational depths.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X170-75 the Right Cylinder?
Choose this 80mm bore when you need higher thrust than the 50mm option (which provides 982N at 0.5 MPa) but do not require the full 3927N push force of the 100mm variant. The SAIJ80X170-75 is selected specifically when a 95-170mm variable end-stop is required, offering greater setup flexibility than a fixed-stroke SAI cylinder. It maintains dimensional interchangeability per ISO 15552 and uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.

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 SAIJ80X170-75 FAQ
At 0.5 MPa, this 80mm bore cylinder provides a push force of 2513N and a pull force of 2268N. At 0.7 MPa, the push force increases to 3518N.
The rear adjuster allows you to shorten the 170mm nominal stroke by up to 75mm, creating a usable travel window of 95-170mm. It functions as a mechanical stop and does not lock the load without live air pressure.
