About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX850-100S
The AirTAC SAIJ160X850-100-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers substantial thrust, providing 14074N push force at 0.7 MPa and a maximum of 18095N at 0.9 MPa. Equipped with a SUS304 stainless steel rod and PT tapered ports, it is built for robust, corrosion-resistant performance.
This model provides a usable travel window of 750 to 850 mm, letting you dial back the nominal 850 mm stroke by up to 100 mm. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches for precise position feedback.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX850-100S Is Used
Large Press Diving
Fine-tune the 850 mm stroke down to 750 mm during setup to accommodate varying die heights without repositioning the entire fixture.
Pallet Positioning
Adjusts the retract stop on the fly to handle different pallet sizes on a packaging line, ensuring exact placement every time.
Heavy Material Handling
Leverages the 18095N push force to move heavy workpieces while allowing a 100 mm travel adjustment for machine changeover.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX850-100S the Right Cylinder?
Choose this 160 mm bore when an application demands higher force than a 125 mm cylinder (which offers 8590N push at 0.7 MPa) but does not require the extreme 21991N push of a 200 mm bore at 0.7 MPa. The adjustable stroke is selected over a fixed SAI cylinder when you need to fine-tune the end position during commissioning or product changeover without adding external stops. Note that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For true load-holding, consider the SAIL or BSAI series.
Because the 850 mm stroke is long and unsupported, an external guide is recommended to prevent rod sag and side-loading damage. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. It is dimensionally interchangeable per ISO 15552 with standard mounting interfaces. Operating speed is 30-500 mm/s.
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 SAIJ160BX850-100S FAQ
This 160 mm bore cylinder generates a maximum push force of 18095N at 0.9 MPa and a pull force of 9425N at 0.5 MPa.
The rear adjuster screw allows you to shorten the effective travel from the nominal 850 mm down to 750 mm, providing a 100 mm window for fine-tuning the retract end position without swapping the cylinder.
