About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X600-30
The AirTAC SAIJ100X600-30 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 600 mm stroke that can be dialed back by up to 30 mm, giving you a precise 570-600 mm usable travel window for exact end-position tuning at commissioning. In the 100 mm bore class, it delivers 3927 N of push force and 3681 N of pull force at 0.5 MPa, making it well-suited for heavy-duty positioning tasks.
This extruded aluminum profile cylinder includes sensor grooves on both sides for flexible switch mounting. It features a 25 mm carbon steel piston rod with an M20x1.5 thread, providing robust resistance to side loads, though the extended 600 mm stroke length still necessitates an external guide to prevent rod deflection. The unit is equipped with adjustable air cushions at both ends to decelerate heavy masses smoothly.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X600-30 Is Used
Variable End-Stop Positioning
Dial in the exact 570 to 600 mm retract position during machine commissioning to accommodate varying material thicknesses without machining custom spacers.
Product Changeover Systems
Quickly adjust the stroke end-limit by up to 30 mm when switching production lines to a new product size, minimizing downtime and avoiding cylinder replacement.
Heavy-Duty Machine Setup
Leverage the 3927 N push force at 0.5 MPa to move heavy fixtures into place while using the rear screw to perfectly square the load against a hard stop.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X600-30 the Right Cylinder?
Choose this 100 mm bore adjustable-stroke cylinder when your application requires substantial thrust—3927 N at 0.5 MPa—and the ability to fine-tune the retract end-stop without swapping components or adding external stops during product changeover. If your process requires less force, stepping down to an 80 mm bore yields 2513 N of push force at 0.5 MPa, whereas moving up to a 125 mm bore provides 6133 N.
The SAIJ100X600-30 uses a G1/2 PT tapered port and supports a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because it lacks a -S magnet, it does not support CMSE reed or DMSE electronic sensors. Remember that the rear adjuster and air cushions act only as travel stops and deceleration; they do not hold the load without live air. For fail-safe load holding, consider an AirTAC SAIL pneumatic lock, a BSAI clamp-lock cylinder, or an external rod lock.

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 SAIJ100 Adjustable Cylinder SAIJ100X600-30 FAQ
The rear adjusting screw acts as an external stopper that mechanically limits the piston's travel. For this model, it shortens the effective stroke from the 600 mm nominal length down to a minimum of 570 mm, providing a 30 mm tuning window without changing the cylinder itself.
At a 0.5 MPa operating pressure, this 100 mm bore cylinder generates 3927 N of push force and 3681 N of pull force. If operated at 0.7 MPa, the push force increases to 5497 N.
