About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX450-50
The AirTAC SAIJ160X450-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 450 mm travel to create a precise 400-450 mm usable window. Delivering a massive 18095 N of push force at 0.9 MPa, it handles heavy-duty positioning with ease. The extruded aluminum barrel features sensor grooves on both sides for flexible switch placement.
This unit features a SUS304 stainless steel rod for superior corrosion resistance and comes with PT tapered port threads. The rear adjuster acts purely as a mechanical stop to fine-tune the end position during commissioning; it does not lock the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX450-50 Is Used
Heavy Machinery Setup
Fine-tune the 400-450 mm travel window during heavy machinery commissioning to achieve exact end positions without machining new hard stops.
Product Line Changeover
Quickly adjust the rear stopper to accommodate different product sizes on a high-force assembly line, reducing downtime between production runs.
Press Positioning
Leverage the 18095 N push force and SUS304 stainless steel rod for robust, corrosion-resistant actuation in precision pressing applications.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX450-50 the Right Cylinder?
Choose this 160 mm bore cylinder when an application demands high thrust—such as 14074 N at 0.7 MPa—and requires exact end-position tuning without swapping physical components. If your force requirements are lower, stepping down to a 125 mm bore yields 8590 N at 0.7 MPa, whereas moving up to a 200 mm bore provides 21991 N. The adjustable stroke is perfect for product changeovers, letting you shift the 400-450 mm travel window on the fly rather than adding external stops.
Because this cylinder features a 450 mm stroke, the 40 mm rod diameter should be paired with an external guide to prevent excessive side-loading on the piston. This model uses PT tapered ports and supports the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). It is dimensionally interchangeable per ISO 15552. As no magnet is specified, position sensing via CMSE or DMSE switches is not enabled on this SKU.
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 SAIJ160BX450-50 FAQ
At 0.9 MPa, this 160 mm bore cylinder provides a push force of 18095 N and a pull force of 9425 N. At 0.5 MPa, the push force is 10053 N.
The rear mechanical adjuster allows you to shorten the effective stroke from its nominal 450 mm down to 400 mm. This creates a 400-450 mm adjustable travel window for fine-tuning end positions at commissioning, but it acts only as a stop and does not hold the load without air pressure.
