About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X155-100S
The AirTAC SAIJ200X155-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive power with a 15708N push and 15080N pull force at 0.7 MPa. A built-in magnet enables position feedback via CMSE reed and DMSE electronic sensors. By turning the external rear screw, you can trim the nominal 155mm travel back by up to 100mm, creating a precise 55-155mm usable window for exact end-position tuning.
This adjustable-stroke design allows operators to fine-tune retract distances at commissioning or during product changeovers without swapping the cylinder or adding external stops. The robust 40mm carbon steel rod and M36x2 thread handle heavy loads well, while the extruded aluminum barrel features sensor grooves on both sides for flexible switch mounting. It uses a PT tapered port and includes variable air cushions at both ends to manage deceleration.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200X155-100S Is Used
Heavy Press Tuning
Dial in the exact 55-155mm pressing distance during machine commissioning to accommodate different material thicknesses without changing the cylinder.
Product Changeover Setup
Quickly adjust the retract end-stop on a packaging line when switching to a new product size, saving downtime on physical mechanical modifications.
Variable End-Stop Positioning
Use the rear screw to set precise lower limits for heavy-duty assembly stations, relying on the 40mm rod to handle high dynamic forces.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X155-100S the Right Cylinder?
Choose this 200mm bore when the 160mm class (14074N push at 0.7 MPa) is insufficient for your heavy machinery needs. An adjustable stroke is preferred over a fixed SAI cylinder when a machine requires variable end-stops or quick setup changes without mechanical retooling. To match this ISO 15552 footprint for a direct replacement, verify the 200mm bore, 155mm stroke, 100mm adjustment, PT port, and the -S magnet requirement.
The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure; for true load-holding without continuous supply, consider the SAIL or BSAI series. Because the 155mm stroke is relatively short for this large bore, side-loading is less of a concern than longer strokes, but external guides are still recommended for optimal rod bearing life.

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 SAIJ200 Adjustable Cylinder SAIJ200X155-100S FAQ
The rear adjuster screw lets you shorten the 155mm nominal stroke by up to 100mm, providing an effective 55-155mm travel window. It functions as a mechanical stop to set the end position and does not lock the load without continuous air pressure.
At 0.7 MPa, it provides a push force of 15708N and a pull force of 15080N. The maximum operating pressure is 1.0 MPa, and it operates at speeds of 30-500 mm/s.
