About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-75S
The AirTAC SAIJ160X135-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 60-135 mm from its 135 mm nominal stroke. Built to handle heavy loads, it generates 14074 N of push force and 9425 N of pull force at 0.7 MPa. The integrated -S magnet enables position feedback via CMSE reed and DMSE electronic sensors housed in the dual-side barrel grooves.
This model features a robust 40 mm carbon steel rod and M36x2 thread, paired with 50 mm variable air cushions at both ends to manage high kinetic energy. The rear mechanical stopper allows precise end-position tuning during commissioning without adding external stops, though it functions purely as a travel deceleration point and does not lock the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-75S Is Used
Heavy-Duty Press Tuning
Dial in the exact 60-135 mm travel window during press setup to accommodate varying material thicknesses without physically swapping the actuator.
Product-Size Changeovers
Adjust the rear stopper on the fly to handle different package dimensions on a packaging line, ensuring precise end-of-stroke positioning.
Automated Assembly Stops
Fine-tune the end-stop position during commissioning of heavy assembly machinery, leveraging the 14074 N push force to move substantial masses.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-75S the Right Cylinder?
Choose this 160 mm bore when the 100 mm bore class (5497 N push at 0.7 MPa) is insufficient for your heavy-duty tooling or clamping demands. The 75 mm adjustment range is ideal for product-size changeovers on a line, letting operators dial in the exact end-stop distance on the fly rather than swapping out a fixed-stroke SAI cylinder. Remember that the rear adjuster and air cushions only set the travel end; for fail-safe load holding without live air, an external rod lock or a SAIL/BSAI locking cylinder is required.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 135 mm stroke, 75 mm adjustment, PT tapered port thread, and the -S magnet requirement. Supported SAIJ mounting interfaces include Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Because the 135 mm stroke is relatively short for this heavy bore, side-load risks are minimal, but external guides are still recommended if the load is cantilevered.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 SAIJ160 Adjustable Cylinder SAIJ160X135-75S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force. The maximum allowable operating pressure is 1.0 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from 135 mm down to a minimum of 60 mm. This provides a 75 mm tuning window for commissioning and changeovers, but it does not lock the load without continuous air pressure.
