About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X200-100
The AirTAC SAIJ80X200-100 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 2513N pull force at 0.5 MPa, paired with a generous 100mm adjustment range that creates a 100-200mm usable travel window. This wide tuning band is ideal for machines processing varying product sizes without requiring physical cylinder swaps.
The extruded aluminum barrel features sensor grooves on both sides for flexible switch mounting. It uses a PT tapered port thread and a 25mm carbon steel rod with an M20x1.5 thread, providing strong resistance against side loads. The rear adjuster acts purely as a mechanical stop to fine-tune the retract position and does not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X200-100 Is Used
Variable End-Stop Positioning
Dial in the retract stroke anywhere from 100mm to 200mm during machine setup to accommodate different material lengths without adding external mechanical stops.
Product Changeover Systems
Quickly adjust the travel window on packaging or sorting lines when switching between different package sizes, minimizing downtime between production runs.
High-Force Clamping Fixtures
Leverage the 2513N pull force to secure heavy workpieces, using the 100mm adjustment range to fine-tune the clamp's retracted clearance.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X200-100 the Right Cylinder?
Select this 80mm bore when an application requires high thrust (2513N pull at 0.5 MPa) alongside extreme flexibility in end-position tuning. If your setup needs less force, stepping down to a 63mm bore yields 1402N pull; stepping up to 100mm provides 3681N. Choose this adjustable SAIJ variant over a fixed-stroke SAI when you need to dial in the retract end-stop during commissioning or product changeovers.
For an exact ISO 15552 replacement, match the 80mm bore, 200mm nominal stroke, 100mm adjustment code, PT port thread, and carbon steel rod. Note that SAIJ supports a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. Because the nominal stroke is 200mm, ensure adequate external guiding if the load is heavy or unsupported. The rear screw stopper only sets the travel end; for load-holding without live air, use an external rod lock or consider the SAIL or BSAI series.

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 SAIJ80X200-100 FAQ
At 0.5 MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. At 0.9 MPa, the push force increases to 4523N.
The rear adjuster screw allows you to shorten the effective stroke by up to 100mm from the nominal 200mm, creating a 100-200mm usable travel window. It functions as a mechanical stop and does not lock the load without continuous air pressure.
