About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX850-40
The AirTAC SAIJ160X850-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering robust performance for heavy-duty automation. It features a 160mm bore and an 850mm nominal stroke, generating a substantial 18095N pull force at 0.9 MPa. The built-in adjustment mechanism allows you to trim the effective travel back by up to 40mm, providing a usable window from 810 to 850mm for precise end-position calibration.
This model incorporates a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides. The rear adjuster functions strictly as a mechanical stop to set the travel end and relies on the integrated air cushions for deceleration; it does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX850-40 Is Used
Heavy Press Tuning
Dial in the exact 810-850mm travel window during press assembly commissioning to accommodate varying material thicknesses without external stopper blocks.
Size Changeover Systems
Adjust the retract end-position on the fly when switching a production line to handle different product lengths, minimizing mechanical retooling time.
Large Fixture Alignment
Fine-tune the stroke end on heavy-duty automated fixtures to ensure precise mating of large components during machine setup.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX850-40 the Right Cylinder?
Choose this 160mm bore cylinder when your application requires high thrust forces up to 10053N at 0.5 MPa, stepping up from a 125mm bore that provides 5734N. The adjustable stroke is ideal for machine setup and product changeovers, allowing you to fine-tune the end position at commissioning without swapping the cylinder or adding external stops. For holding loads without live air pressure, consider the SAIL or BSAI series instead, as the SAIJ adjuster is not a locking mechanism.
Because this model features an 850mm stroke, the long unsupported piston rod requires an external guide to prevent excessive side-loading and premature seal wear. It maintains dimensional interchangeability per ISO 15552 mounting interfaces and uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).
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 SAIJ160BX850-40 FAQ
This 160mm bore cylinder delivers a push force of 10053N and a pull force of 9425N at 0.5 MPa. The 40mm rear adjuster allows you to shorten the 850mm nominal stroke, providing an adjustable usable travel window of 810 to 850mm.
No, the rear adjuster acts only as a travel stop to set the end position and works with the air cushions for deceleration. It is not a locking mechanism; for load-holding without live air pressure, use an AirTAC SAIL or BSAI cylinder.
