About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX160-40S
The AirTAC SAIJ100X160-40-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 5497 N of push force at 0.7 MPa and features a 25 mm piston rod with an M20x1.5 thread. The built-in rear stopper allows you to trim the effective travel, providing a usable stroke window of 120-160 mm for precise end-position tuning during commissioning.
This variant includes a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and carries the -S magnet option for seamless integration with AirTAC CMSE reed and DMSE electronic sensors. It utilizes PT tapered ports and includes variable air cushions at both ends to decelerate heavy loads smoothly.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX160-40S Is Used
Product Changeovers
Quickly dial the stroke back by up to 40 mm when switching between product sizes on the line, avoiding the need to physically swap out cylinders or reposition hard stops.
End-Position Tuning
Fine-tune the exact retracted position during machine commissioning to perfect seating or clamping forces without altering the fixed mechanical framework.
Heavy Forming Operations
Leverage the 5497 N push force at 0.7 MPa for pressing or forming tasks, using the adjustable window to control the precise depth of travel.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX160-40S the Right Cylinder?
Choose this 100 mm bore cylinder when an application requires substantial thrust—such as 5497 N at 0.7 MPa—that exceeds the 2182 N push force of the smaller 63 mm bore. The adjustable stroke is ideal for product changeovers on a line, allowing you to dial in the end-stop from 160 mm down to 120 mm without swapping the cylinder or adding external stops. If you need to step down force, the 80 mm bore offers 3518 N at 0.7 MPa.
For any stroke at or above 300 mm, an external guide is recommended to support the rod and prevent excessive side-loading, though this 160 mm unit is well within standard unsupported limits. Remember that the rear adjuster acts only as a travel stop, not a lock; the SAIJ100X160-40-S cannot hold a load without live air. For true load-holding, consider the SAIL or BSAI series. This model is dimensionally interchangeable per ISO 15552 and uses the standard SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ100AX160-40S FAQ
At 0.7 MPa, this 100 mm bore cylinder provides 5497 N of push force and 3681 N of pull force. At maximum 1.0 MPa pressure, it achieves 801 kgf. The operational speed range is 30-800 mm/s.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from its 160 mm nominal length down to 120 mm. This creates a 120-160 mm usable travel window for fine-tuning the end position without changing the cylinder itself.
