About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX200-100
The AirTAC SAIJ160X200-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust for heavy-duty automation. Based on a 160mm bore, it generates 14074N of push force at 0.7 MPa. The integrated rear stopper allows you to dial back the 200mm nominal stroke by up to 100mm, providing a highly flexible 100-200mm usable travel window for precise end-position tuning during commissioning.
This unit features a SUS304 stainless steel rod (option B) for superior corrosion resistance and carries a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. Because the rear adjuster acts only as a mechanical stop and the standard air cushions manage deceleration, neither component will hold a load without live air pressure—external locking mechanisms are required for static holding.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX200-100 Is Used
Heavy Machinery Setup
Fine-tune the 100-200mm travel window during heavy equipment commissioning to achieve precise mechanical positioning without machining new spacer blocks.
Product Size Changeovers
Rapidly adjust the rear stopper on a packaging line to accommodate different product heights, leveraging the 100mm trim range to switch formats quickly.
Corrosive Press Operations
Utilize the SUS304 stainless steel rod in damp or chemically exposed pressing stations where a standard carbon steel rod would degrade.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX200-100 the Right Cylinder?
Selecting this 160mm bore model provides 14074N push force at 0.7 MPa; if your application requires less force, stepping down to a 125mm bore yields 8590N, whereas moving up to a 200mm bore offers 21991N. The 100mm adjustment range is ideal for product changeovers on a line, allowing you to shift the end-stop without physically swapping the cylinder or adding external stops. For load-holding without continuous air supply, you must integrate an external rod lock or look at the SAIL or BSAI series, as the SAIJ adjuster is strictly a travel stop.
When replacing an ISO 15552 cylinder, match the 160mm bore, 200mm nominal stroke, 100mm adjustment range, PT port thread, and your required mounting style. The SAIJ series supports a specific mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Although the 200mm stroke is under the 300mm side-load warning threshold, the 40mm rod and M36x2 thread provide excellent rigidity, but heavy loads should still be properly guided.
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 SAIJ160BX200-100 FAQ
At 0.7 MPa operating pressure, this 160mm bore cylinder provides 14074N of push force and 9425N of pull force. At 0.5 MPa, the push force is 10053N.
The rear adjuster acts as a mechanical stop, allowing you to shorten the effective travel from the 200mm nominal stroke down to 100mm. This creates a 100-200mm usable window for fine-tuning end positions without altering the cylinder mount.
