About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX375-75
The AirTAC SAIJ160X375-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a robust 10053N pull force at 0.5 MPa and incorporates a 50mm variable air cushion at both ends. The integrated rear stopper allows you to trim the effective travel, creating a 300-375mm usable stroke window for precise positioning without changing the entire unit.
This specific SKU is configured with a SUS304 stainless steel rod (option B) for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches. Because the rear adjuster acts only as a travel stop and does not lock the load, an external guide is recommended for this 375mm stroke to manage side loads.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX375-75 Is Used
Press Fit Tuning
Dial in the exact 300-375mm travel window during machine commissioning to perfect press depths without adding external mechanical stops.
Product Changeover
Quickly adjust the end-of-stroke position on automated lines when switching between different product sizes or tooling profiles.
Heavy-Duty Forming
Leverage the 14074N push force at 0.7 MPa for heavy bending or forming tasks, using the rear screw to fine-tune the material deformation limit.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX375-75 the Right Cylinder?
Selecting this 160mm bore over a smaller 125mm bore jumps the thrust from 6136N to 10053N of pull force at 0.5 MPa, providing the extra power needed for heavy pressing or clamping. The 75mm adjustment range is ideal for product changeovers on a production line, letting operators dial in the exact end position without swapping hardware or adding external stops.
When ordering, match the bore, stroke, adjustment, PT port, and SUS304 rod material. Note that this SAIJ model supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. For applications requiring true load-holding without live air pressure, consider the AirTAC SAIL or BSAI clamp-lock series instead.
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 SAIJ160BX375-75 FAQ
The rear adjusting screw acts as an external stopper that lets you shorten the nominal 375mm stroke by up to 75mm, giving a usable travel window of 300-375mm. It functions as a travel limit, not a lock, and does not hold the load without live air pressure.
At 0.5 MPa it provides 10053N of push force and 9425N of pull force. At 0.7 MPa, the push force increases to 14074N, making it suitable for heavy-duty industrial applications.
