About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-30
The AirTAC SAIJ160X140-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a massive 14074N push force at 0.7 MPa. It features a 40mm carbon steel rod and a G3/4 PT tapered port to handle high flow demands. By turning the rear screw, you achieve a precise 110-140mm usable travel window without swapping hardware.
This adjustable stopper lets you dial in the exact retract end-position during commissioning or product changeovers. The extruded aluminum barrel includes sensor grooves on both sides, and because no magnet is specified here, you can add an -S version later to support CMSE reed or DMSE electronic solid-state switches.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-30 Is Used
Heavy Press Tuning
Fine-tune the 110-140mm retract distance on heavy pressing equipment to accommodate different material thicknesses without external stops.
Product Changeover
Rapidly adjust the end-of-stroke position during production line format changes, saving downtime by using the built-in 30mm trim window.
Assembly Station Setup
Leverage the 14074N thrust for robust assembly operations while precisely setting the stroke limit during initial machine commissioning.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X140-30 the Right Cylinder?
Choose this 160mm bore when a 100mm bore (providing 5497N push at 0.7 MPa) lacks the necessary thrust, but step up to a 200mm bore if you need the maximum 21991N output. The -30mm adjustment code is ideal for machinery requiring variable end-stops between 110 and 140mm. It uses a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
Remember that the rear adjuster acts only as a travel stop, not a lock; this SAIJ will not hold a load without live air, so specify a SAIL or BSAI cylinder if load-holding is required. For a direct ISO 15552 replacement, match the 160mm bore, 140mm stroke, -30mm adjustment, G3/4 PT port, and carbon steel rod. Although the stroke is under 300mm, the heavy 40mm rod thread handles substantial side loads, yet an external guide remains best practice for rigid stability.
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 SAIJ160X140-30 FAQ
At 0.7 MPa operating pressure, this 160mm bore cylinder provides a push force of 14074N and a pull force of 9425N. It can reach a maximum push force of 18095N at 0.9 MPa.
The rear adjuster screw allows you to shorten the nominal 140mm stroke by up to 30mm, creating a usable travel window of 110-140mm. This stopper fine-tunes the end position but does not lock the load without continuous air pressure.
