About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX200-75S
The AirTAC SAIJ160X200-75-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a substantial 10053N push force at 0.5MPa and features a robust 40mm SUS304 stainless steel rod. The integrated magnet allows for direct position sensing using AirTAC CMSE reed or DMSE electronic switches. With PT tapered port threads, this unit is built for demanding industrial environments.
This specific SKU provides a 125-200mm usable travel window, allowing you to dial back the nominal 200mm stroke by up to 75mm. This built-in adjuster acts purely as a mechanical stop for end-position tuning during commissioning; it does not lock or hold the load without live air pressure. For applications requiring true load-holding without continuous air supply, an external pilot-operated check valve or a dedicated SAIL locking cylinder is required.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX200-75S Is Used
Heavy Press Fine-Tuning
Dial in the exact 125-200mm end-stop during heavy press commissioning to ensure perfect crimping depth without machining custom external spacers.
Variable Product Changeover
Quickly adapt the retract position for different sized parts on a single line by adjusting the rear screw up to 75mm, drastically reducing setup time.
High Force Positioning
Leverage the 10053N pull force at 0.5MPa to shift heavy pallets, using the rear stopper to guarantee precise mechanical positioning at the end of travel.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX200-75S the Right Cylinder?
Choose this 160mm bore when you need heavy thrust that exceeds the 6136N push force of the 125mm bore, but want to avoid the massive 15708N output of the 200mm series. The 75mm adjustment range is particularly valuable on production lines running mixed product sizes, as it allows operators to fine-tune the retract end-stop without swapping the physical cylinder or adding external stops.
When integrating this cylinder, note that the SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets, intentionally omitting the FB, CA, CB, and CR options. Because the stroke is 200mm, the 40mm SUS304 rod handles high side loads well, but any lengthy unsupported travel still necessitates an external guide to prevent binding. To replace an existing ISO 15552 cylinder, match the 160mm bore, 200mm stroke, 75mm adjuster, PT G3/4 ports, the chosen mounting bracket, and the -S magnet requirement.

- ✓ 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 SAIJ160BX200-75S FAQ
At 0.5MPa, this 160mm bore cylinder generates 10053N of push force and 9425N of pull force. The maximum operating speed is 30-500mm/s, and it features a 50mm air cushion at both ends to decelerate the heavy load.
The rear adjuster screw lets you shorten the effective stroke from 200mm down to 125mm. This creates a 125-200mm travel window for precise end-position tuning during setup, but the adjuster functions only as a travel stop and does not lock the load without live air.
